how to write key A and Key B onto WS1850S

[huanfai]

I recently get a M5 Dial V1.1 and I have card with mifare 1k card encrypted with known key A/B and read data from block 1.
I used to work with Arduino and rc522 and it works fine.
Now I tried to migrate my project to M5 Dial and a had some problems on writing authentication keys on WS1850S and get feedback of authentication status.
in UIFlow 2's RFID instruction didn't mention about the encryption things.

Hello @huanfai

looking at the soucre code for UIFlow2 device firmware I think authentication keys are fixed to default values. See here and here.

In ohter words I don't think the RFID blocks in UIFlow2 can handle anything different than default authentication keys.

Thanks
