In the Configuration -> Configure Module page assign:
- GPIOx to
SerBr Tx (71) - GPIOy to
SerBr Rx (72)
If the RFID Tag is held in front of the Antenna the reader starts sending the Tag ID. The Tag Id is prefaced with a 0x02 and the end is delimited with a 0x03. If the reader reads the tag multiple times you would get one line with multiple times the Tag ID. For this to seperate you can add a SerialDelimiter of 0x03. This will split the result from the serial into serveral single mqtt messages. But (probably) all the messages wil be prepended with a binary 0x02.
Set SerialDelimiter to 3
SerialDelimiter 3
