WIFI, Bluetooth classic and BLE

[fz@zie.ch]

I want to use via AT Commandos WIFI, Bluetooth classic and BLE (not simultaneously). My ESP32-WROOM-32 has the following SW :

AT version:2.1.0.0(883f7f2 - Jul 24 2020 11:50:07)
SDK version:v4.0.1-193-ge7ac221
compile time(0ad6331):Jul 28 2020 02:47:21
Bin version:2.1.0(WROOM-32)

AT Command for WIFI and BLE work.
Commands for Bluetooth Classic do not work. (ESP32 answer ERROR)

Do I doing something wrong?
Is there a binary file I can load?
If possible i want to work with AT Commands.

Thanks for your help
Felix
