ESP32 Forum

Using the ESP-AT firmware is there a way to configure it to start some sort of wireless serial connection at power on so that AT commands can be sent over this wireless connection?

The requirement I have is that the ESP32 device is not electrically connected to the controlling device, so any available method would be acceptable.

I assume that once a Bluetooth or BLE SPP connection is established then AT commands can be sent over this link, for example to read data from the ADC. However it seems that a physical UART or USB connection is required to send the commands to initially configure such a link.

Is this possible and are there other options?

Hi,
you can git pull the latest code and use the socket interface.

enable it in menuconfig:
python build.py menuconfig > Component config > AT > communicate method for AT command > AT through socket
