Board

ESP32 Dev Module

Device Description

ESP32 attached to power source

Hardware Configuration

Only power source connected, LED used is on the board

Version

latest master (checkout manually)

IDE Name

Arduino IDE

Operating System

Description

I ran the example code RMakerSwitch and I'm unable to do the BLE Provisioning. I have an iOS and when I tried again with an android it worked. I've also tried using the RainMaker BLE Provisioning app which does work but it doesn't add the device so I can't see it on the RainMaker app.

Debug Message

it is not able to connect to the wifi

Other Steps to Reproduce

It worked on Android.

I have checked existing issues, online documentation and the Troubleshooting Guide

@sanketwadekar - Could you please take a look? Thanks!

@Ankita-Dasgupta please specify the version of ESP32-Arduino and iOS version. Also, check if your Rainmaker app is updated. Thanks

I am not the OP but I can confirm this does not work with Arduino 2.0.16 but using 2.0.6 (Last version I know to work) does provision properly. I'm not sure its an iOS problem as I also saw it on Android - the problem is in Rainmaker itself. My module ESP32 Wroom, 4Mb, Arduino IDE 2.3.2, Win11. @sanketwadekar (I can test more versions but this will run me out of node space on the dashboard).
