ST67W611M1 Module Firmware Update

Dear all,

 

ST67W611M1 is a wonderful module that STM could fulfil the gap for wireless connectivity compared to ESP32, while performing design for the prototype board, I found that the WIKI page did not mention any future update capability and requirements for update. Can any ST member answer this question for me? 

1. Do I required perform USART connectivity for runtime firmware update?

2. Can I update the module via BLE same as stm32wb/stm32wba series?

3. Please advise all methods to update the module.

 

Thank you all in advance.

Hi JowyC,

1. UART is needed for wired binary update. UART connection should be provisioned on your PCB board for wired update in your factory. This however shouldn't be necessary in the field if you plan to rely on OTA updates alone.

2. Currently the module's firmware can be updated OTA via Wi-Fi only. OTA update via BLE will be possible in a next software release.

3. As you must have figured, "wired" update over UART, OTA over Wi-Fi and in the future over BLE are the update methods.

Best regards,

Tarik
