I have ESP-07. I am trying to use it as a microcontroller that will read values from sensors attached to GPIO pins then broadcast their values over wifi connection.
At this point I have connected ESP-07 to FTDI chip and I am able to send AT commands to it. However, I have no idea how to communicate with the GPIO pins.
Can someone please guide me as to how I can communicate with GPIO pins?
It does not seem that I can do this with AT commands, which means I either need to flash the module or ... ?
I appreciate any help
