Hi,
You code looks ok. However, I noticed strange thing when testing with
Android phone on my side: pairing fails if specified passkey has less
than 6 digits (i.e. <100000). This does not seem to be issue in NimBLE
since the same happens when trying to pair Android with BlueZ while
pairing between NimBLE and BlueZ works just fine. Looks like some
issue in Android LE SC implementation tbh...
So please try with 6 digits passkey (i.e. >=100000) and it should work.
Best,
Andrzej
