NFC DT Android app with external NFC reader

I’m using an Android phone without NFC capabilities. I’ve been able to overcome this with an on the go USB cable, which allowed me to connect the ACS ACR122u reader/writer to the device.
I can see the device and read/write cards with apps that specifically look for it (NFC Tools, ACR122 Reader Utils…), but it looks like the DangerousThings NFC app doesn’t.
Any way to force it to recognize that as NFC reader?

Hmmmmm… no idea!

Oh ok :smiley: Any chance I might have a look privately at the .apk source code so that I could see to adapt it for external readers through USB?
