Other Parts Discussed in Thread: CC3200, CC3100, CC3135
We are using Wi-Fi module CC3135MOD (https://www.ti.com/product/CC3135MOD#product-details) to develop a medical device and we need to perform SAR measurements.
We are trying to use the Radio Tool GUI to connect to the module on our board but, since we do not have direct access to the module (the board is closed in its case during the tests), we are using a microcontroller as bridge between the USB and the UART of the module.
The USB is configured as CDC, so it is seen as a COM port from the PC. In the microcontroller, we de-assert the RESET and the hibernate PIN, then we just wait to USB and UART messages to arrive.
At the power on, we see that the module sends 148 bytes, where the only readable part is the name of the SSID previously configured, and the first part matches the bytes reported here: BOOSTXL-CC3135: CC3135 UART porting issues - How to reset device in host initialization - Wi-Fi forum - Wi-Fi - TI E2E support forums.
Following this thread, we tried to send the specified packet with Docklight, but the module is not responding. Does it mean that our bridge is not working well? The additional bytes reporting the SSID name are expected?
Then we tried to connect with the Radio Tool GUI but setting the device as CC3100 UART, the tool fails at the connect step, while setting it to CC3200 UART the connect is successful, but then the device information are not retrieved (the module is not replying to the 4 bytes sent from the tool, that are 0x77 0x00 0x99 0x4E, so there is no trace about the sync word mentioned in the linked thread..).
Which is the right device to set?
Thank you, regards
