I've finally managed to get the latest firmware (ESP8266_NONOS_SDK) onto a ESP01 module.
Via AT-commands I can control the GPIO (finally)
But is it possible to control the GPIO's from another device when (let's say), the ESP is in AP mode?
Is there a way to read the state of a GPIO (or ADC), or set the output for a certain IO via a TCP GET or PUT request?
My question is: how can I control these GPIO's from another device (client) without other controllers?
(please very basic)..
