Bluetooth pairing problem with iOS

Hi,

I am developing a product, based on nrf52840 soc with SDK v15.3 and softdevice V14. I have a pairing problem with the recently released iOS, version14. while my product works well with older iOS versions and all android devices.

The problem is in this manner that, my device sends a pairing request to the iOS14 but iOS doesn't respond to the request and the request encounter with a timeout. the same problem occurs when I try to pair with iOS14 with the nrfConnect desktop version (which uses PCA10056 as a BLE adaptor).

But I could pair iOS14 with the nrfConnect android version and windows BLE interface.

i have attached the sniffer log for 

1) My product fails to pair with iOS14. ->  3187.ios_pair_failure.pcapng

2) Windows pairs successfully with iOS14. ->8372.ios_pair_success_windows.pcapng

Could anyone help me to solve the problem?

thanks

  • Thank you so much,

    Yesterday Apple released a new update for iOS which I've installed today (iOS14.2 beta2). it seems that after installing it the problem was solved and it pairs with our product as it did in iOS13.

    as it is a beta release, maybe apple commits it to the stable version, maybe not.

    Anyway, I will be very grateful if you update us with a workaround to change key distribution options.

    Best regards

    Alireza
