While tinkering with ESP8266/ESP32 projects and have ran aground and need some help from the comunity.
I am trying to send a packet that consists on an array of 6 by n parameters from a mobile to an ESP8266/ESP32.
I have been looking at JSON but cannot make sense of it can anyone provide any tips or point me to some reading material.
I have managed to send sensor data to an SQL db via PHP from an ESP8266/ESP32 via POST but cannot make sense of sending data to the ESP8266/ESP32.
Thank you.
