Hi everyone.
I would like to ask you to check my code.
The code is used to communicate arduino nano with nde mcu. Arduino Nano sent every 1 sec a data packet in json format from temperature sensors.
I have a problem with intercepting this data in node mcu.
Please give me some suggestions.
I would be very grateful for help
