Mobile phone compatibility for RainMaker Android App using ESP32S2 (MEGH-3184) #17
Description
I tried the LED Light example using IDF Release 4.3. ESP32 boards work without issue. But ESP32S2 just cannot be added using Poco X3 NFC mobile phone.
Another ESP-C3 with factory flashed LED Light example works with this mobile phone.
After scanning the QR Code, a small window showing:
Connect to device
ESP Rainmaker app wants to use a temporary Wi-Fi network to connect to your device
PROV-xxxxxx
After clicking Connect, a single line of message "Connection successful" is shown, but it jumps to another window showing:
Device connection failed.
Do you want to connect device manually
After clicking Yes, the app open a full screen for asking Connect to Device PROV_xxxxxx. Clicking Connect and get it connected, but RainMaker is still showing Connecting and finally change the button to Connect again.
From my mobile, I find it is really connected to PROV-xxxxxx. But it just can't be added even I tried other ESP32S2 boards, including SOLO and Saola.
The strange thing is another LG mobile phone works with these ESP32 devices. Rainmaker app just does not show the above windows, but showing Select Wi-Fi Network directly with a message:
To complete setup of your device, PROV-xxxxxx, please provide your Home Network credentials.
The RainMaker app version is 2.4.1 - 21c2060 is used for Poco X3 NFC from PlayStore. APK direct link, version 2.0.2 97f5372 from Espressif is also used with exactly the same problem.
