Niimbot support #48

Open kris0725pl opened 1 year ago

D11 and B21 please ;)

I have the Niimbot label printer and a BLE capture tool, but the tool only has software support for Windows (which I don't use). I ordered a cheap NUC and when it arrives, I'll try to reverse engineer the NIIMBOT protocol.

Are you going to probe the TX/RX for data traffic?

I try today...ok

Whoa! I found way to print without TAG on any stickers on D11. There is a little bug in firmware :)
