”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.

Power Save mode does not work when in Access mode. In order to save power, AT
Commands, ZP=2 and ZP=6, can be used to allow the MCU to sleep and reduce the beacon intervals by turning the radio on/off at a duty cycle.
The eS-WiFi modules support multiple power saving modes. Please see the power savings application note for more detailed information. For power critical applications
please contact Inventek for alternative low power modes.
7.1.2 Stop Mode
Stop Mode is initiated by software and exited by the an input on the Wakeup pin.
(Wakeup pin is 3.3 volt tolerant). The wakeup pin is an external interrupt pin that on the rising edge will cause the module to exit stop mode. It is an edge trigged input. It is critical to have no glitch on this line.

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:

SERIAL HOST INTERFACES AVAILABLE
UART, SPI and USB-HID host interfaces are supported and unique firmware is required for each interface.
10.1 UART
A universal asynchronous receiver / transmitter (UART) with 3.3v logic levels is available.

ISM43362-M3X Product Specification
10.1.1 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).
10.1.2 Flow Control
The eS-WiFi module doesn’t require or support Flow Control, so Flow Control should be
‘None’
10.1.3 Supported Baud Rates
The eS-WiFi module uses USART1 (PA9 and PA10 of the STM32F205) and the following serial baud rates are supported: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200,
230400, 460800, 921600, 1152000, 1382400, 1612800, 1834200, 2073600. USART1 can be run at higher rates but have not been tested with the AT command set.
10.1.4 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.
10.2 SPI (Serial Peripheral Interface Bus)
The eS-WiFi module supports SPI (Contact Inventek for specific firmware.)

10.2.1 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.
SPI Master
“AS=0,ABC\r\x0A”
“AD\r\ x0A”

Read Messages
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.
10.2.2 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.
DOC-DS-20071-3.3.1
Page 18
Inventek Systems
Ex. S3=0010\r0123456789
ISM43362-M3X Product Specification
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).
10.2.3 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.
DOC-DS-20071-3.3.1
Page 19
Inventek Systems
ISM43362-M3X Product Specification
10.2.4 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.
10.2.5 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.

PRODUCT COMPLIANCE CONSIDERATIONS
RoHS: Restriction of Hazardous Substances (RoHS) directive has come into force since
1st July 2006 all electronic products sold in the EU must be free of hazardous materials, such as lead. Inventek is fully committed to being one of the first to introduce lead-free products while maintaining backwards compatibility and focusing on a continuously high level of product and manufacturing quality.
EMI/EMC: The Inventek module design embeds EMI/EMC suppression features and accommodations to allow for higher operational reliability in noisier (RF) environments and easier integration compliance in host (OEM) applications.
FCC/CE: The module will be in compliance test for FCC/CE

18.2 Device baking requirements prior to assembly
Boards must be baked prior to rework or assembly to avoid damaging moisture sensitive
components during localized reflow. The default bake cycles is 24 hours at 125C.
Maintaining proper control of moisture uptake in components is critical.
Before opening the shipping bag and attempting solder reflow, you should maintain a minimal out-of-bag time and ensure the highest possible package reliability for the final product.
Module’s Assembly Instructions
Board Placement: The ISM43362-M3G-L44 has an optional on board Wi-Fi antenna.
The board is designed to be a stuffing option. If you elect to use the on-board antenna, then board placement is critical in your system. Several key items to consider when placing the module are:
Ensure that the antenna portion of the design is placed so that the antenna has no ground plane under, above or near the antenna. Ideally, the antenna requires clear sky for optimal performance. If you have shields or other material around the antenna, please test for interference and loss of signal strength.
