ESP32-C6 is crashing when BlueDroid is used. (MEGH-5841)

[P-R-O-C-H-Y]

Answers checklist.

• I have read the Rainmaker documentation and the issue is not addressed there.
• I have updated my IDF branch (release/vX.Y) to the latest version and checked that the issue is present there. This is not applicable if you are using Rainmaker with Arduino.
• I have searched the Rainmaker forum and issue tracker for a similar issue and not found a similar issue.

IDF / ESP32-Arduino version.

ESP-IDF v5.1.3-1012-gd82f9162df

Operating System used.

macOS

How did you build your project?

Command line with idf.py

Development Kit.

ESP32-C6 DevKitM-1 V1.0

What is the expected behavior?

The switch example is expected to work on C6 using BlueDroid as for all other chips BlueDroid with RainMaker works fine.
In Arduino we use BlueDroid as the BLE provider, and C6 is not working.

I was able to reproduce the issue using IDF with the RainMaker switch example, changing just few things in the SDK Config.
With the same SDK config it's working fine on ESP32-C3.
Partition table was changed to just single OTA partition, to fit the binary when BlueDroid is used.

What is the actual behavior?

Crashes on simple_ble: Configuration mismatch. Select BLE Only or BTDM mode from menuconfig.
But there is nothing in menuconfig to fix the issue.

Steps to reproduce.

I have created a project on GH to easily reproduce the issue.
Just build and flash.

Hi @vikramdattu, Thank you for quick reply. Your proposed fix is working fine.
Will you also back port this fix for v5.1 release of IDF?

[vikramdattu]

@P-R-O-C-H-Y yes the fix will be back ported to all the eligible IDF branches including release/v5.1
