I have been fighting with this issue for about a month,
I have 4 external Rs232 connected devices connected to 2x ESP32
ESP's are interconnected between them using Serial2 (UART2) first esp acts as master and have an lcd and a keyboard when a code is entered, this code is then forwarded to slave and indicates readiness for receiving data,
Each ESP makes a GET request to a server once data is received on rs232,
the problem is that it works at completely random,when each rs port is tested separately i can get all the readings done.
When all ports receive data at the same time (rs devices are sending data virtually at the same moment) very often data is lost most often slave uart 1 ( serial1 ) does not get any data in the buffer (completely deaf)
each string starts with a digit number and ends with "\n\r"
Is there any obvious mistakes in the codes below?
