<![CDATA[How to set end of line character in UART]]>I'm using UI flow 2.0. My UART device has special ascii char for end of line (0x7E). I believe EOL is detected using line feed by default 0x0A.. Is there a way to set custom end of line character in the UART initialization?

uart1 = UART(1, baudrate=115200, bits=8, parity=None, stop=1, tx=32, rx=26, txbuf=256, rxbuf=256, timeout=0, timeout_char=0, invert=0, flow=0)

ok, understood.

Well, you cannot set a different EOL character and therefore you cannot use UART block read line.

However you can use block count of available and read 1 bytes etc. to read chars sent from your device. As long as the char received is not your EOL char, append them into a buffer. And when you receive your EOL char do something with the chars accumulated in the buffer, then clear the buffer and start over.

It's UHF RFID reader device that sends newly read tag data with 7E at the end.

you can use UART x write "" block which will send data without line end and then use UART x write raw Data 0x7E to send the special line end.
