NimBLE & SerialBT Same TIme Crashing

[Bwanna]

Setup: ESP32 DevKit C

Issue: NimBLE & SerialBT crash when running same time. (core ESP32 BLE & SerialBT run fine) -I'm not yet experienced enough to decode the error msg and offer any suggestions. Any Suggestions?

Below is the Code and the Error Msg: Sketch: `/*

NimBLE is BLE only, classic Bluetooth cannot be used with this library.

h2Zero,

Just to verify... the BluetoothSerial.h can't be used in the same sketch with the NimBLEDevice.h ?

Thanks,

[h2zero]

That's correct.

Thank you for the information.
