The N5 ANT SoC module series starts with the M8 model in a 14.0mm x 9.8mm x 2.0mm LGA (Land Array Grid) package. A compact design meeting the market requirements for small, light and wearable, the M8 model is a turnkey system hardware solution including antenna, onboard 32 kHz and 16 MHz crystal clocks, DC/DC converter and 24 GPIOs with 6 analogue inputs. The N5 modules are pre-programmed with the following software components: • • • S210 SoftDevice (scalable ANT protocol stack with max. 15 channels) ANT network processor application ANT-WP (Wireless Programming) bootloader SoftDevices are protocol stack solutions from Nordic Semiconductor for the nRF51 SoCs. There are multiple SoftDevice choices available from the Nordic Semiconductor’s web site. The ANT network processor application provides the standard ANT serial interface front-end that is connectable to an external application controller. The ANT-WP bootloader allows over-the-air updates of any software components on the N5 module. The N5 module’s pre-programmed image can be easily replaced via the onboard SWD interface pins using off-theshelf ARM programming tools or over the air using the pre-loaded ANT-WP bootloader. Pin compatible options for the 20mm x 20mm AP2 or C7 modules from Garmin Canada Inc. (formerly Dynastream) are also available. In these M4 and M5 model options, N5 M8 models are soldered on carrier boards that are pin compatible to the previous modules. Current AP2 or C7 module customers can easily use these models to evaluate the hardware and upgrade their products. The N5 module series, if loaded with the ANT and/or BLUETOOTH low energy stack has been certified to comply with radio regulation or standards covering major markets include North America, Europe, Australia, New Zealand and Japan. The N5 ANT SoC modules series has also been qualified by the BLUETOOTH SIG. 1.1 Nomenclature Figure 1: N5 ANT SoC Module Series Nomenclature thisisant.com N5 ANT SoC Module Series, Rev 2.2 1.2 Page 9 of 37 Production Tracking Code For technical support and customer service purposes, a production code of three characters is laser marked on the RF shield as illustrated below.

Depending on the module revision, the preloaded code varies. Please refer to Appendix C: N5 Module Pre-Loaded Software Versions. • S210 SoftDevice - Refer to nRF51422 S210 SoftDevice Specification • ANT-WP Bootloader - Refer to Appendix B: Using the ANT Bootloader for OTA Firmware Update • ANT Network Processor Application - Refer to Appendix A: Using the ANT Network Processor Configuration Figure 7: Memory Map of the Preloaded Software 2.4 N5 Module Programming The N5 ANT SoC module series supports two programming methods: • Standard Serial Wire Debug (SWD) interface • Over-The-Air (OTA) updates using the preloaded ANT-WP bootloader (Not available for N548 Rev A) These two programming methods are complementary. While the ANT-WP bootloader offers the convenience of programming wirelessly, it does consume some of the available application space. In case the space for the bootloader must be reclaimed for a large application, programming via SWD interface would be the option. The three software components (the SoftDevice, the bootloader and the application code) must be version compatible to operate properly. Because each individual component can be reprogrammed, it is not safe to always assume the default factory image on a module by reading the module revision mark and referring to the history of thisisant.com Page 14 of 37 N5 ANT SoC Module Series, Rev 2.2 preloaded images as summarized in Appendix C: N5 Module Pre-Loaded Software Versions. When versions of the software components are unclear, to ensure proper operation after reprogramming, it is recommended that the module undergoes a full erasure (e.g. using the erase-all option in nrfjprog.exe/nRFgo Studio) and all desired software components be explicitly programmed onto the module. Some reference application code is provided on https://www.thisisant.com/developer/components/n5/. 2.4.1 Programming via SWD Interface The N5 ANT SoC Module series supports the Serial Wire Debug (SWD) interface SWDCLK and SWDIO (refer to Table 3). Programming and debugging of the module only require common available tools, such as the Keil software development environment and the Segger J-Link programmer. Please refer to “nRF51422 Evaluation Kit - Developing with the MDK-ARM Microcontroller Development Kit” from Nordic Semiconductor for a specific reference on using the Keil software and J-Link programmer. It is important to note that the BOOTLOADERADDR field in the UICR is set to the starting bootloader address location by default. If the desired programmed application needs to reclaim the bootloader region and/or if bootloader support is not required, then the BOOTLOADERADDR field in the UICR must be set to 0xFFFFFFFF. The erase-all command via nrfjprog.exe/nRFgo Studio should reset this field. Please refer to Figure 7: Memory Map of the Preloaded Software. 2.4.2 Programming Over the Air The pre-programmed SoftDevice and ANT-WP bootloader in the N5 ANT SoC Module provides over-the-air firmware update capability. The pre-programmed ANT Network Processor Application provides two methods of entry into the bootloader mode in order to perform the software updates. SoftDevice, bootloader and application code in the module can be changed or updated in this manner. Please refer to Appendix B: Using the ANT Bootloader for OTA Firmware Update. 2.4.3 Initializing the SoftDevice The N5 module comes with 50ppm onboard 32 kHz crystal. When initializing the SoftDevice, it is important to set the crystal accuracy to be 50ppm. In the preloaded ANT Network Processor code, this line is used: sd_softdevice_enable(NRF_CLOCK_LFCLKSRC_XTAL_50_PPM, softdevice_assert_callback) 2.4.4 Configuring the DC/DC Converter The N5 module can make use of the DC/DC Converter on supported nRF51422 chip revisions. This can improve power consumption under certain conditions. sd_softdevice_enable(NRF_CLOCK_LFCLKSRC_XTAL_50_PPM, softdevice_assert_callback) 2.5 Design Considerations RF performance is always affected by the environment. Good design makes a product less susceptive. Guidelines provided in this section are for recommendations only. Users should thoroughly test their products in the intended use cases and make necessary modifications and trade-offs. For design assistance purpose, a STEP model package of all the three module types and an Altium library of the M8 module are provided online. 2.5.1 M8 Module Mounting Best RF performance is achieved by using 0.032" thickness FR4 under the module antenna and following the guideline on Figure 8. thisisant.com N5 ANT SoC Module Series, Rev 2.2 Page 15 of 37 Figure 8: N5 M8 Module Mounting (all dimensions in mm) 2.5.2 M4 Module Mounting Best possible RF performance is achieved when the module is placed such that the module antenna is protruding out from the mating PCB into free space as Figure 9. Place no exposed copper underneath the M4 module. If possible, place continuous ground plane under the module. Figure 9: N5 M4 Module Mounting 2.5.3 M5 Module Mounting The mating socket is Molex 52991-0208. Note: The M5 module is provided for application prototyping and lab use. The M5 module should not be used to evaluate the RF performance of the N5 module family. 2.6 Assembly Considerations 2.6.1 Moisture Control The moisture control of the module is rated at level 1 defined by IPC/JEDEC J-STD-020. The modules do not require special storage conditions provided: • They are maintained at conditions equal to or less than 30 °C/85 % RH, and • They are solder reflowed at a peak body temperature which does not exceed 260 °C thisisant.com Page 16 of 37 N5 ANT SoC Module Series, Rev 2.2 To ensure good solderability of the PCB pads, it is highly recommended to always have the modules intended for reflow well sealed when in storage. 2.6.2 Solder Stencil Design of M8 Module The following reference stencil design is used to produce N5 M4 and M5 models. Figure 10: Solder Stencil Reference 2.6.3 Cleaning Process The module is made using no-clean solder paste. No-clean process is recommended. thisisant.com N5 ANT SoC Module Series, Rev 2.2 3 Page 17 of 37 Regulatory Approvals and Compliances The N5 ANT SoC module series, when loaded with ANT and/or BLUETOOTH low energy stack, has received regulatory approvals in the United States (FCC) and Canada (IC), and has been verified to conform to the appropriate regulations in Europe, Australia and New Zealand, and Japan. The module series has been qualified by BLUETOOTH SIG. Such approvals and qualification allow the user to place the module inside a finished product and, in most cases, not require regulatory testing for an intentional radiator, provided no changes or modifications are made to the module circuitry. This does not preclude the possibility that some other form of authorization or testing may be required for the finished product. Changes or modifications could void the user’s authority to operate the equipment. The end user must comply with all of the instructions provided by the Grantee, which indicate installation and/or operating conditions necessary for compliance. 3.1 United States The N5 ANT SoC module series has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: - Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. The N5 module series complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. The N5 module series does not contain any user-serviceable parts. Unauthorized repairs or modifications could result in permanent damage to the equipment, and void your warranty and your authority to operate this device under Part 15 regulations. The N5 module series is labelled with its own FCC ID, O6R2398 (note: First Character is the letter O, not the # 0.)

ANT-WP Bootloader Activation The pre-programmed ANT Network Processor Application provides two methods of entry into the ANT-WP bootloader mode. The methods are described in the following sections. thisisant.com Page 30 of 37 N5 ANT SoC Module Series, Rev 2.2 Once the ANT-WP bootloader has been activated, the N5 module will remain in bootloader mode until one of the following conditions are met: • The existing network processor application is successfully replaced using the ANT-WP bootloader and the new application is activated. • The existing network processor application is not replaced. The ANT-WP bootloader successfully disconnected from ANT PC OTA updater tool. • The existing network processor application is not replaced. The ANT-WP bootloader reaches 2 min inactivity timeout. For more details on the ANT-WP bootloader functionality, please refer to Appendix B: Using the ANT Bootloader for OTA Firmware Update. Using BOOT Pin A dedicated BOOT pin is assigned in the network processor application in order to activate the ANT-WP bootloader code. If BOOT is held high upon power-up or start-up, the operation of the network processor code is bypassed and the ANT-WP bootloader code is started. The intent of this functionality is to assist in updating/replacing the default images on the N5 modules using the OTA firmware update capability of the ANT-WP bootloader without requiring host microcontroller intervention. This mode of operation is not intended to be used to upgrade the existing network processor application on the N5 module. Using Serial Command The following serial command message has been defined in the ANT network processor code. A host microcontroller can issue this command to the ANT network processor application to put the N5 module into the ANT-WP bootloader mode. Sync Length MsgID 0x02 0xE4 Payload 0x00 Chksum 0x00 Table 11: ANT OTA Update Enable Command After issuing the command, the following response is generated prior to activation of the ANT-WP bootloader. Sync Length MsgID 0x04 0xE0 Response 0x00 0xE4 0x00 Chksum 0x00 Table 12: ANT OTA Update Enable Response Note: Sync and Chksum values are defined in the document “Interfacing with ANT General Purpose Chipsets and Modules”. A response of 0x00 indicates successful pending ANT-WP bootloader activation. The N5 module enters the ANTWP bootloader mode shortly after sending the response. Serial communication to the module is not available when the bootloader is active. This mode of operation can be used to upgrade the existing ANT network processor application on the N5 module. When exiting the ANT-WP bootloader mode, an ANT startup message will be generated by the network processor application code. Refer to Start-up Message in the document “ANT Message Protocol and Usage”. thisisant.com N5 ANT SoC Module Series, Rev 2.2 Page 31 of 37 5. DC/DC Configuration Note: this feature is not provided on the N548 models. The pre-programmed ANT Network Processor Application provides a method of configuring the DC/DC converter on the module via Serial Command. This allows modules featuring compatible ICs to use the DC/DC features of the nRF51422. Please refer to the nRF51422 Product Specification v3.1 for details on the DC/DC (Sections 3.4 and 8.5 particularly). DC/DC should only be used on appropriate modules. The following serial command message has been defined in the ANT network processor code. A host microcontroller can issue this command to the ANT network processor application to configure the DC/DC operation on the N5 module. Sync Length MsgID 0x02 0xE4 Payload 0x01 Chksum 0x00 – DC/DC Disable 0x01 – DC/DC Enable Table 13: ANT DC/DC Configuration Command After issuing the command, the following response is generated.

A response of 0x00 indicates successful configuration of the DC/DC. thisisant.com Page 32 of 37 N5 ANT SoC Module Series, Rev 2.2 Appendix B: Using the ANT Bootloader for OTA Firmware Update The ANT bootloader supports over-the-air firmware update using ANT File Share (ANT-FS) technology. The following features are supported: • Application updates with or without existing application on the device • Bootloader updates • SoftDevice updates, including swaps from S210 to S310 and vice-versa • Combined SoftDevice and bootloader updates A primary ANT bootloader demo and reference code is provided in the nRF51 SDK. The N5 module (except for N548 Rev A) is preloaded with the ANT-WP (Wireless Programming) bootloader that is specially made to work with the ANT Network Processer code. 1. Operational Memory Layout The UICR BOOTLOADERADDR is set to the starting address of the bootloader image. The operational memory layout is shown in the figure below: 0x040000 ANT-WP Bootloader 0x03B800 Bank 1 Application Bank 0 Code Region 1 Free App Size SD Size 0x001000 0x000000 Code Region 0 SoftDevice MBR Figure 18: ANT-WP Bootloader Operational Memory Layout • ANT-WP Bootloader: Occupies the reserved flash region between 0x3B800 – 0x40000.

Responsible for receiving, processing, storing and activating received images in banked regions Bank0/Bank1. • Master Boot Record (MBR): Occupies region 0x0000 – 0x1000. Manages system startup and interrupt forwarding to the bootloader and the SoftDevice. Used by the ANT-WP bootloader in order to execute the SoftDevice and bootloader image swaps and verification. The MBR is non-updateable and is initially programmed in along with the SoftDevice. • SoftDevice: Occupies flash region starting at address 0x1000, with size depending on the specific SoftDevice (S210/S310) used. Contains ANT protocol stack and SoC interface components used by the ANT-WP bootloader and the ANT Network Processor application code. • Application Code/Swap Region (Bank0/Bank1): The remaining space is divided into two memory banks of equal size, BANK0 (starting after the SoftDevice) and BANK1 (ending before the bootloader). If an application is present in the device, it is placed in the space right after the SoftDevice, and depending on its size, may occupy part or the entirety of BANK0, and none, part or the entirety of BANK1. During image reception, the ANT-WP bootloader uses the banked region(s) as storage space for the incoming image. The memory region allocation is summarized in the table below: Usage Memory ranges (Using S210 V4.0.1 or V5.0.0) Memory ranges (Using S310 V2.0.0 or V3.0.0) ANT-WP Bootloader 0x3B800 – 0x40000 0x3B800 – 0x40000 Application Code / Swap Space 0xD000 – 0x3B800 0x1D000 – 0x3B800 SoftDevice 0x1000 – 0xD000 0x1000 – 0x1D000 Master Boot Record (MBR) 0x0000 – 0x1000 0x0000 – 0x1000 Table 15: Summary of the ANT-WP Bootloader Operational Memory Layout 2. Entering Bootloader Mode If there is no existing application on the device, the device will always start in bootloader mode. In the case of an existing application being present, to enter bootloader mode, the application must request bootloader entry by writing to a shared memory block field in the bootloader code region. Application Programming Interfaces (APIs) used to request bootloader entry are provided in the example N5 ANT Bootloader Demo code mentioned in the document “N5 Module Starter Kit User Manual”. The following files provide the interface. • ant_boot_settings.h • ant_boot_settings_api.h • ant_boot_settings_api.c For more information regarding the shared memory block field between the bootloader code and the application, please refer to the aforementioned “N5 Module Starter Kit User Manual”, under Passing Information between Application and Bootloader. 3. Bootloader ANT-FS Functionality Upon entering bootloader state, the ANT-FS-client code is initiated. ANT-FS is a session based transport mechanism designed to handle data file transfers between two ANT enabled devices. A detailed description of ANT-FS is available in the document “ANT-FS Technical Specification”. The specific details of the over-the-air message exchange used for the update process as defined by ANT-FS are outlined in the application note “ANT AN Over the Air Firmware Updates Using ANT-FS”, including the format of files exchanged. thisisant.com Page 34 of 37 N5 ANT SoC Module Series, Rev 2.2 As indicated in the “N5 Module Starter Kit User Manual”, a customized PC implementation of an ANT-FS host used to perform OTA updates (OTA Updater Tool) is provided.

Pairing or passkey authentication methods are not supported in the current version. 4. OTA Firmware Update Procedure Before updating any image component of the N5 module, it is important to review the release notes and test all image components for compatibility. Example Usage The following procedure is a basic example of how to use the provided ANT-WP bootloader code and OTA Updater Tool PC application to perform an OTA firmware update. thisisant.com N5 ANT SoC Module Series, Rev 2.2 Page 35 of 37 Figure 20: OTA Updater to PC Application 1. Connect an ANT USB stick to the PC 2. Start the OTA Updater application. The status bar at the bottom should indicate “Ready” 3. Configure the Connection Settings. Use the configuration specified in Table 17: ANT-WP Bootloader ANT-FS Device Identification Parameters. a. Specifying the ANTFS_CLIENT_SERIAL_NUMBER (obtained by reading the DEVICE[0] FICR field of the module) will allow the OTA Updater application to connect only to the specified module. b. Specifying 0 (wildcarding) will allow the OTA Updater application to connect to any module in the bootloader state. 4. Configure the Authentication Settings. The ANT-WP bootloader uses pass-thru authentication by default. Passkey authentication is not supported in this version. 5. Browse for the image to update, and make sure the corresponding checkbox is checked. Both binary and hex formats are supported. 6. Initiate the bootloader mode on the target N5 module. Use the bootloader entry methods described in Entering Bootloader Mode section or Bootloader Activation of Appendix A: Using the ANT Network Processor Configuration. 7. Click on “Connect to Device”. Once the bootloader is discovered, the Device Information panel will show information about the current device, e.g., manufacturer ID, product ID, serial number and versions of the images currently installed on it. thisisant.com Page 36 of 37 N5 ANT SoC Module Series, Rev 2.2 8. Click on “Start Update”. The update process will begin. 9. When the update is complete, the status bar will indicate “Image upload complete. Image will be activated, do not power down device”. Image Activation N5 module will remain in the bootloader mode if there is no valid existing application. Preservation of an existing application code may not be guaranteed and can be overwritten by temporary banked data during ANT-FS file transfer. Therefore, it is important to understand the conditions where this can occur. • Attempting to update the SoftDevice will always invalidate an existing application image • Attempting to update the bootloader or application, by default, will invalidate an existing application image unless the current application notifies its current usage size using the shared memory block field as described in the “N5 Module Starter Kit User Manual” under Passing information between Application and Bootloader. However, if the passed in size value exceeds the size of a single bank region (see Operational Memory Layout), the existing application image cannot be preserved across firmware update. • If the size of the image update file being transferred during the ANT-FS session exceeds the size of a single bank region, the existing application image will be invalidated. thisisant.com N5 ANT SoC Module Series, Rev 2.2 Page 37 of 37 Appendix C: N5 Module Pre-Loaded Software Versions Module Version S210 Softv5.0.0Device ANT-WP Bootloader ANT Network Processor Code N550 and N5150 V5.0.0 (AXX5.00B00) BFD2.00B00 BAW4.00B00 N548 rev B V4.0.1 (AXX4.00B00) BFD1.00B00 BAW3.00B00 N548 rev A V3.0.0 (AXX3.02B00) None BAW2.02B00 Table 18: N5 Module Versions and Factory Loaded Software 1.
