Hello all,

How to update the Wifi SSID/Password using Bluetooth on AMB82 Mini ? I don’t want to use the Realtek app but my own. Please guide,

Thanks

Hi @roq ,

You may refer to the example BLE WiFi Configuration and source code for reference.

Your app should first establish a Bluetooth connection with AMB82 MINI, request the board to scan for WiFi network and send the scan results back to the app using BLE.

After selecting the right AP from the scan results, your app should send the ssid and password back to the board to set up WiFi connection and disconnect BLE thereafter.

Thank you.

Hi @KevinKL , thanks for the response ! I have got most of the chip working nicely now, only the bluetooth part remains.

I went through this example, BLE – WiFi Configuration Service – Realtek IoT/Wi-Fi MCU Solutions , to try to set the Wifi SSID/password using bluetooth on my AMB82 as you had shared

However, my phone (tried both iPhone and Android) cannot find the bluetooth of the AMB82 after running the code. I tried multiple examples, including the BLEScan, BLEUARTService, etc. but my phone and my laptop cannot find the Ameba. It seems the AMB82 cannot be discovered.

How can we make the Ameba findable, so we can connect via BLE and send commands ?

Hi @roq ,

Apologies for the late response, I was able to find AMB82 using nRF app on my iPhone. You may use nRF or Bluefruit Connect app to discover AMB82 once the example code is uploaded.

Thank you.

Hello all,

Hey, I’ve done something similar before. To update the Wi-Fi SSID/password on the AMB82 Mini using Bluetooth, you’ll want to use a Bluetooth serial terminal app. Pair your device with the AMB82 Mini, then send the commands to update the Wi-Fi settings. Check the device’s manual for the exact command format you need. It’s a bit fiddly, but it should work.
