RE: Added BAS service to nfc peripheral example caused phone to disconnect (0x13)

Hi Jerome,
I suspect that the attribute table has been cached and not updated on the phone. This will cause a mismatch when you add the BAS service to the device. Please try to delete the bond information on the phone, reset Bluetooth (reset phone if needed) and test again.
You can try adding this:
CONFIG_BT_GATT_SERVICE_CHANGED=y

So that the phone should know that the attribute table may change and it should do service discovery when receive a notification. But this only works if the attribute table has not been cached.

If you add the BAS service to other sample, do you see the same issue on the S23 ?
