Task watchdog aborts btController at BluetoothSerial.begin()

[rajendrapk@yahoo.com]

On my ESP32-Wroom32 Dev Module (*NOT* on earlier Developement Boards that I successfully tried!!)
I get the following error and ESP32 restarts, as soon as the code hits the BluetoothSerial.begin() statement.

What is wrong?
The SAME code is running well on Development Boards.
I also attempted with a little larger power supplies. No luck.
Also attempted hitting that code after a delay(). No luck.

Am I missing something?

Can you decode that backtrace?

Hi ESP_Sprite and everyone,

I tried with different CPU / Flash settings and it started working at
CPU 240 MHz,
Flash Speed 40 MHz,
Flash Mode DIO and
Partition Default...SPIFF.

I think earlier I had selected the lowest CPU Hz value (40 MHz) thinking that "Lower the *SURE* it works", but looks like I was wrong!

BTW ESP_Sprite, how to decode the backtrace? .. is it, manually converting each hex byte into ASCII and looking for any meaningful English Text?
