BT classic configured in power-up

[yaramb]

Hello,
I'm using the ESP-AT project in a ESP32-MINI1. It's working well.
I need to enter BT Classic Passthrough mode on power-up, using SPP profile and saving the configuration in flash. There is a command (AT+SAVETRANSLINK) for Wi-Fi and Bluetooth LE but not for BT classic.

Does anyone know how to how to manage it for BT Classic?

Thanks in advance
