Problem Description

I have activated the bt classic and I am able to use some BT classic commands as "AT+BTINIT=1" or "AT+BTSPPINIT=2" but I can not use "AT+BTSECPARAM" it does not appear when you use "AT+CMD?" command. I need it because it seems to be mandatory to make work SPP over windows. Has it been removed?
Expected Behavior

AT+BTSECPARAM=3,1,"9527"

OK
Actual Behavior

AT+BTSECPARAM=3,1,"9527"

Is your firmware compiled by yourself ?

I see that the IDF version used in the information you provided is 4.2, so I guess the AT firmware you are using is AT 2.2.0.0. Please refer to https://docs.espressif.com/projects/esp ... aries.html and download the the corresponding version to test.
