The ESP8266 is connected to Serial1 on the Mega and I am using Serial0 to print to the serial monitor over USB. The longer I transmit E1.31 data, the latency increases when reading the output on the Mega. I’ve been able to get it to work but there is latency in the serial transmission. The ultimate goal is to control RGB pixels. I am attempting to use an ESP8266 to read E1.31 (SACN) data over WiFi and then send it out to a Mega 2560 over serial.
