Write with RDM6300

[Jerome67]

Hi,
i use your code for read some RFID 125Khz card with EPS8266 + RDM6300, it's working (thanks a lot) but i have some RFID 125khz card blank ( with modifiable UID - sector 0 ).
Can i use RDM6300 for write UID on these new cards ?
Thanks

Hi,

This library only conectes to the TX pin of the RDM6300 - it can only read the bytes it sends - it can't write any byte to it.

I didn't found any documents of using the RDM6300 RX pin in order to send a "write UUID" command..
(maybe the RDM6300 doesn't supports 125kHz RFID writes? it may require different hardware to perform writes?)

After a bit of googling I found this repo that seems to supports read / write for both 125kHz and 13.6MHz RFID cards:

If it works for you please update here so me and others can also use it :)
