So, Hendrik, of Labmaker GmbH, has discovered the location of the new ETAGRFID firmware that I couldn't find. He's a true hero. Thank you, Hendrik. And here's the link: https://github.com/Eli-S-Bridge/ETAG_V10
I received an ETAG_RFID board from Labmaker. The serial output at startup includes features not seen in the ETAG_4095 sketch I found online dated 5-4-18. New setup features include I = Set device ID, M = Change logging mode, and W = Write flash data to SD card. Can anyone point me to the repository or send me a copy of this alternate sketch? I want to know what I may overwrite with my changes, and not shoot myself in the foot!
