I am working on a project that uses the esp8266-01 module with Arduino UNO
I connected my setup and used Serial communication with AT commands to try and send data to a remote server through Wi-Fi
However, no matter what i do, I cannot get the TCP protocol to initiate reliably, it sometimes fails and gives an error message, and these happen to be completely random, i could not figure out a cause whatsoever.
