Bluetooth not pairing - S2120

I cannot pair via bluetooth to the S2120 using the SenseCap Mate Android app.

I have tried two S2120s and three phones, all with the same result.

The phones can find the S2120s via bluetooth, but cannot pair. I have tried 000000, 1234 and 0000 pairing codes.

Any advice on how to get it working?
