Hello, I am working on a project which connects an arduino mega and an ESP8266 nodemcu to AWS. The mega reads from several different sensors, sends a JSON file over to the nodemcu and then on to AWS. I have the nodemcu connected to AWS but something is wrong with my serial connection to the arduino. I created fake test values to be sent by the arduino mega but the nodemcu isnt receiving the correct values. Instead it either comes through as zero or null. Looking for some help with this please!
