Hello,
Recently I'm dealing with ESP-AT to use esp32-wroom as bluetooth dual mode module.

First I tried to enable bluetooth classic,
and build.py said I need to optimize features to use this firmware becuase more IRAM is required.

Since no other features(like ethernet, wifi, ...) are needed,
I disabled all the other features at build.py menuconfig.

However, as you expected, a huge amount of errors occur.
(Now I understand that what menuconfig said - do not change if you don't know what are you doing!)

So, is there any references or guidance documents for dealing with menuconfig?
Please let me know.

Thank you in advance.

could you please disable features like the attachment p1.png shows, it works well on my side.

If it still cannot work, please provide more information (full compile logs, sdkconfig file, etc).

Hi,

Thank you for providing the guide.

I followed your guide and the build was successful, but SPP is not working.

Here are the details:

It happens with ESP32-WROOM using locally compiled ESP-AT firmware.
ESP32-WROVER using offical ESP-AT firmware does not show this error.
BTINIT=1, BTSPPINIT=1, BT+SPPCONN=0,0,"addr" successfully connects.
The BTSPPSEND command outputs ">".
The device immediately reboots after typing any character.

Here are the logs:
