In order to utilize P0.21 as a hardware reset, the user information configuration registers, (UICR) PSELRESET[0] and PSELRESET[1], must both be set to the value of 0x7FFFFF15. When P0.21 is programmed as RESET, the internal pull-up is automatically enabled. Nordic Semiconductor example applications and development kits program P0.21 as RESET_N. Debug and programming The BMD-350 series supports the two pin Serial Wire Debug (SWD) interface and offers flexible and powerful mechanism for non-intrusive debugging of program code. Breakpoints, single stepping, and instruction trace capture of code execution flow are part of this support. BMD-350 also supports ETM and ITM trace. Trace data from the ETM and the ITM is sent to an external debugger via a 4-bit wide parallel trace port. In addition to parallel trace, the TPIU supports serial trace via the Serial Wire Output (SWO) trace protocol. Clocks BMD-350 requires two clocks, a high frequency clock and a low frequency clock. The high frequency clock is provided on-module by a high-accuracy 32 MHz crystal as required by the nRF52832 for radio operation. The low frequency clock can be provided internally by an RC oscillator or synthesized from the fast clock, or externally by a 32.768 kHz crystal. An external crystal provides the lowest power consumption and greatest accuracy. Using the internal RC oscillator with calibration provides acceptable performance for Bluetooth low energy applications at a reduced cost and slight increase in power consumption. ☞ The ANT protocol requires the use of an external crystal.

These resources give access to the very latest Bluetooth support from Nordic Semiconductor and provide an ongoing development path as new features are released. ☞ For legacy applications, source code is provided through our GitHub repositories for RigDFU, BMDware, Rigablue, developer tools, and mobile apps. The code allows customers to customize and extend their own development applications. Factory image The factory programmed firmware version is indicated on the label. Programming of the factory image is maintained solely for legacy applications. New development should use the latest Nordic Semiconductor SDK and examples. 4.1.1 • • • • Firmware version “AA” RigDFU v3.2.0 (42) Nordic Semiconductor S132 SoftDevice v2.0.0 BMDware v3.1.0 (50) Read-back protection enabled.

Module programming and read-back protection For legacy applications, RigDFU allows for UART and OTA updates to RigDFU, the SoftDevice and application firmware. In order to utilize the SWD port on “AA” and “AB” marked modules, the nRF52832 must be erased and recovered. Without this step, the module will not be recognized by most programmers. This is accomplished through nrfjprog, which is provided with the Nordic Semiconductor command line utilities: nrfjprog -f nrf52 ––recover ☞ A full chip erase is performed, so all components must be reloaded (Bootloader, SoftDevice and application firmware). The BMD-350 module may be restored to the factory firmware versions noted above with the utilities available at our GitHub repositories. SoftDevices Nordic Semiconductor protocol stacks are known as SoftDevices. SoftDevices are pre-compiled, pre-linked binary files. SoftDevices can be programmed in nRF52 series SoCs and are downloadable from the Nordic Semiconductor website.

The area under and extending out from the antenna portion of the module should be kept clear of copper and other metal on all layers. The module should be placed at the edge of the PCB with the antenna edge facing out. Reducing the ground plane from that shown in Figure 7 will reduce the effective radiated power. Figure 7: Recommended RF layout and ground plane Mechanical enclosure Care should be taken when designing and placing the BMD-350 into an enclosure. Metal should be kept clear from the antenna area, both above and below. Any metal around the module can negatively impact RF performance. The module is designed and tuned for the antenna and RF components to be in free air. Any potting, epoxy fill, plastic over-molding, or conformal coating can negatively impact RF performance and must be evaluated by the customer.
