Description

when I try to connect it to the Wi-Fi network using the Rainmaker app it gives me the following error message "Error, No Bluetooth device found with the given prefix"

I tried with both BLE and SoftAP methods and both don't work and when I go on the Wi-Fi and BLE scanner I dont even see it on the list of devices.

Debug Message

None.

Other Steps to Reproduce

I tried with 2 different ESP32's but I am getting the same result. I am not able to detect the ESP32 via BLE or SoftAP mode.

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

Since you are using Git, could I bother you to switch to the esp32-s3-support branch and give it another go? We have updated RainMaker in that branch

[gcohen10]

I am not using ESP32-S3 and also not using git. I am using Arduino IDE with a normal ESP32 WROOM module. What does git have to do with it ?
When I flash the Arduino example I don’t see any errors. I just see the QR code and URL link when I scan it I get an error message telling me the following:
“No Bluetooth device found with the given prefix“ I get the same message for BLE and SoftAP method and I can’t see the device in the BLE and Wi-Fi scanner.

[me-no-dev]

that branch support all other chips + ESP32-S3 and has updated code in many places. I asked you so because that is what you posted above:

Version

latest master

[gcohen10]

Sorry I meant to write master branch.

[gcohen10]

Rainmaker partition scheme is only available for ESP32 Dev Module on Arduino. I cannot see that option on any other module on the boards manager. does the partition scheme matter ?

[me-no-dev]

you should not need a special partition and since you are using ESP32-WROOM, you can safely select the "ESP32 Dev Module". It covers ALL ESP32 modules and variants (not S2, S3 C3, etc.). And is you are using "master branch" then you still say that you are using the git version of this repo and you could just go in there and git checkout esp32-s3-support to switch to the branch I asked :)

[gcohen10]

OK. But why can’t I see the device PROV_1234 in the Wi-Fi and BLE scanner ?

[me-no-dev]

did you try the new branch? RainMaker in master is very old (more than a year)

[gcohen10]

I only tried the master branch

[me-no-dev]

And are you willing to try the other branch? Your other option is to wait until we merge it into master and then you update your local copy.

[gcohen10]

I will try the other branch
