I am using the Cottonwood UHF RFID reader (TTL/UART version)

The reader is made to communicate through X-CTU software. I was able to successfully read the tags after following this tutorial-

I am using the Arduino Uno as a UART-USB breakout. This is the schematic

After opening X-CTU, I go to the...

Thanks for that data sheet. Unfortunately is is not very good. While all the actual words are in English there is little sense in it.

How did you decide the baud rate was 9600? While it mentions the baud rate in the fault finding section:-


baud rate is not set in accordance

Their is no other mention of what speed it should be. Unless you know this then you can not hope to get it to work.

What have you done with the trigger input? It says in another of those poor phrasings :-


When reader in tigger work way, if make down-lead...

Get distance from an RFID Tag [solved] - Arduino Forum

Dear Arduino community,

Hi there,

I've got an IR+RFID guided robot. I have to target many objects in a room, one after the other. All are in a random position. Each one is RFID passive-tagged.

I proceed like that: I target an object with the IR, I reach it, and I check if the target is the right one with an RFID validation.

A way for that is to roughly compare the IR measured distance and the RFID measured distance, and to conclude if the target where we are going is the right one. I even think that compare...
