ESP32 Forum

I want to use the ESP32s in it's default AT command mode, but I need a pin to go high or low when a bluetooth connection is made, e.g. an led light up when connected. I want the firmware to work as intended but I really need a status pin and preferably have it do this by default, even after a reset. Is this possible? Is it already built in somewhere?

Hi,

I don't think if you can do this without modifying the ESP-AT project for your needs.
One possible solution is to implement on your host MCU, by using the AT+DRVPWMINIT command.

Hope this could help you!
