Serial Communication with external Device an Wemos D1 Mini

[Y-V-L]

Hello,

i am just struggeling on using RX from Wemos D1 mini, just receive noting.

I have a RFID Animal reading Modul  (Download Manual). I had tested it with UART -> USB Converter, an i was able to read alle the stuff on a Terminal.

So i connect the Module to GND/5V/RX of the Wemos D1 and whatever i do i was not able to read any Data ...

What i already had done:

Rule Setup 

Rule1

on System#Boot do Backlog SerialLog 2; Baudrate 9600; SerialConfig 7; SerialSend 2 endon

Is it generally possible (on using RX/TX) ?

Here in Documentation i can read and read an i did not see why it should not work:

https://tasmota.github.io/docs/Commands/#serial-bridge

Thanks vor Help.

Hello,

ok, it is solved now, it's working.

The problem was very mystic ... after debugging and testing with the string i received on Serial Terminal i was able to send this sting to the RX Pin ... and i also received nothing ....

So the module is sending some ESC Sequences at the end wich Tasmota can not handle .. ( Decimal: 226 and some more ....)

But it is also sending a lower case "z" at the end ....

With setting the SerialDelimiter to 122 (which is the lower case "z") Tasmota is now recieving the information from the Module ....  

Thanks

Yves.
