android: Unable to read/write NFC tag

Android version: 10

Phone model: Oneplus7

Home Assistant version: 114.4

Last working Home Assistant release (if known): n/a

Description of problem: I cannot read or write an NFC tag which I can otherwise read or write fine using the “NFC tools” app.

Traceback (if applicable): n/a

Screenshot of problem:

Additional information: As you can see in the screenshot I have written a small text “by nfc tools” to the tag, so nothing should be wrong with the tag imo

In the normal version of the app I don’t have a NFC Tags section in the App Configuration. However, in the debug version you shared, there is a NFC Tags section and I can successfully read the tag.

sounds like you got something corrupted…in order to show the NFC section we check that the device reports it has the proper hardware and that HA version is at least 0.114. I think you may need to clear data especially if the debug version looks correct since that part of the code did not change. Follow these steps:

@Armadill0 not a bother at all, its helpful for us to know this because we don’t all use the same devices and they are not all built the same or function the same 😃 I will leave this issue open for a few more days to let others respond.

The solution was to allow NFC for Home Assistant application(it was disabled for me): Touch and hold the HA application icon > App info > Other permissions > NFC > Accept

@shmirgel Man that worked, thank you very much! 😃

Can everyone else with this issue check this on their device? My device does not have this option so NFC is always available.

@dshokouhi Checked, now works for me, sorry for bothering.
