1 GENERAL DESCRIPTION
The Inventek ISM4334x-M4G-L44 is an embedded wireless internet connectivity
module that operates in the 2.4 & 5.0 GHz spectrum. The Wi-Fi module’s hardware
consists of an ARM Cortex M4 host processor, Broadcom BCM43341/0 Dual-Band (2.4
GHz / 5 GHz) 802.11 a/b/g/n MAC/Baseband/Radio with Integrated Bluetooth 4.0 and
NFC support. The module has two antenna options, an on board dual band chip 2.4 & 5
GHz or an U.FL connector for external 2.4 & 5 GHz antenna.
There are two versions of the module offered, one that supports NFC (ISM43341-M4GL44) and one that does not (ISM43340-M4G-L44).
The module provides UART and SPI interfaces enabling connection to an embedded
design. The Wi-Fi module requires no operating system and has a completely integrated
TCP/IP Stack. The module hardware can be used with Inventek’s AT Command set
(IWIN) or with Broadcom’s WICEDTM SDK3.1.2 or later.
Inventek’s IWIN, AT command set, allows you to quickly establish connectivity for your
wireless product, minimizing development time, testing routines and certification. The low
cost, small foot print (14.5 mm x 34 mm) and ease of design-in make it ideal for a range
of embedded applications.

8 FIRMWARE UPGRADES DURING DEVELOPMENT
We recommend using a JTAG 10 pin header or directly connecting to the JTAG pins
on the module for updating. Use the ST-Link to flash the ST micro.
Below are links to the ST-Link and JTAG header at Digikey:
STLink:
http://www.digikey.com/product-detail/en/ST-LINK%2FV2/497-10484-ND/2214535

*JTAG Firmware Update Note can be found at www.inventeksys.com
9 SERIAL HOST INTERFACES AVAILABLE
UART, and SPI host interfaces are supported and unique firmware is required for each interface.
9.1 UART
A universal asynchronous receiver / transmitter (UART) with 3.3v logic levels is available.
Data Mode
When the eS-WiFi module is interfaced serially, the serial interface needs to be configured
for 8 bit data, no parity, and one stop bit -- (8-n-1).
Flow Control
The eS-WiFi module doesn’t require or support Flow Control, so Flow Control should be
implemented.
Supported Baud Rates
The eS-WiFi module uses USART1 (PA9 and PA10 of the STM32F405) and the following
serial baud rates are supported: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200,
230400, 460800, 921600, 1152000, 1382400, 1612800, 1834200, 2073600, 2304000,
2764800, 3686400, 3910800. Please note that higher baud read does not always correlate to
higher throughput.
Default Serial Configuration
The eS-WiFi module is shipped with the default serial configuration of 115200 baud, 8 data bits, no
party, and 1 stop bits.

Note: All commands to the eS-WiFi module must be post-padded with 0x0A (Line Feed) to an

All data from eS-WiFi module will be post-padded with 0x15(NAK) to an even number of bytes.
SPI Communication Overview:
With the exception of initial cursor, all communication with the module happens synchronously.
In other words, the SPI Master must always poll for every asynchronous event.
A typical command flow is provided flow. This is an example using the Direct Connect Soft AP
with a TCP communication server.

Note: [SOMA] - Start of Message Asynchronous, [EOMA] - End Of Message Asynchronous
The SPI communication is always 16-bit and can be sustained up to 20MHz. The eS-WiFi
module after power up or reset will raise CMD/DATA READY pin to signal that the first Data
Phase has started. In this mode, the SPI Host must fetch the cursor. As provided by the example
above, this is the only time host needs fetch data from slave without issuing a command.
The Host will initiate a SPI cycle (lower SSN) and clock out 0x0A (Line Feed) until the
CMD/DATA READY pin lowers signaling the end of the Data Phase. The data received will be
0x0d (CR) 0x0A (LF) 0x3E (>) 0x20 (SP).
The next rising edge of the CMD/DATA READY pin signals the Command Phase.
SPI Command Phase:
The Command Phase indicates the eS-WiFi module is ready to accept an AT Command. The
command must include all delimiters and data for the command.
Ex.
S3=0010\r0123456789
The command must also be sent as one continuous SPI cycle, that is SSN must stay low for the
complete command, delimiters, and data.
The Host will initiate a SPI cycle (lower SSN) and clock out the command, delimiters and
associated data and raise the NSS signal to indicated that the all data has be sent. As result of the
NNS raising the eS-WiFi module will lower the CMD/DATA READY pin to signal the end
Command Phase.
The data that will be clocked back to the Host will be 0x15 (NAK).

SPI Endian Example:
The data is in little endian (0x15 0x15 0x0A 0x0D 0x20 0x3E) and needs to be converted back to
big endian with the leading 0x15’s removed. Please remember that this is a 16-bit interface so
the endian conversion is done one 16-bit at a time.
The endian requirement extends to the command being sent to the module. So a “I?\r\x0A”
command would be sent as 0x3F 0x49 0x0A 0x0D.

SPI Data Phase:
The Data Phase indicates the eS-WiFi module has data ready for the Host to read. The eS-WiFi
module will raise CMD/DATA READY and the Host will initiate a SPI cycle (lower SSN) and
clock out 0x0A (Line Feed) until the CMD/DATA READY pin lowers signaling the end of the
Data Phase.
SPI Asynchronous Messages:
There are certain situations in which the eS-WiFi will issue asynchronous messages:
Soft AP (AO/AD Commands), when a device connects to the Soft AP a DHCP assigned
message will issued.
Ex. [DHCP ] Assigned 00:00:00:00:00:00 has 192.168.10.100
TCP/UDP Communication Servers (P5=1), when a client connects to the server a
connected message will be issued.
Ex. [TCP SVR] Waiting on connection...
[TCP SVR] Accepted 192.168.10.100:2000
[UDP SVR] Accepted 192.168.10.100:2000
With the SPI host interface being synchronous the Host must poll for these messages. This can
be done by using the MR (Message Read) command or when a Communication connection the
issuing of a R0 command will read all asynchronous message and the result of the R0 command.
The asynchronous messages are delineated by the Start Of Message Asynchronous ([SOMA])
and End Of Message Asynchronous ([EOMA]) markers.

11 ANTENNA
11.1 External Antenna
The Inventek U.FL PCB antenna is certified for FCC, IC and CE. The part number is W2.4-5PU. It is a dual band 2.4/5 GHz PCB antenna with a U.FL connector.
The Inventek W2.4-5P-U PCB antenna datasheet can be found on the Inventek Website.
11.2 Mechanical Specifications
Figure 2: Chip Antenna Keep out Area
”Keep out” area should ideally have the antenna hanging off the side of the PCB for
best performance. If you do not hang the antenna off the PCB, ensure no ground planes
or traces are placed under the antenna (keep out area). Surrounding metal will affect
the antenna performance. The external antenna does not require “keep out” area
12 ON BOARD PROCESSOR
