Hi,

Probably not related to attribute caching then. I misread your description and thought you had to reboot the phone, not just restart the app.

To me, it sounds like this could be related to the problem considering iOS doesn't expose any methods or properties for bonding. I don't have experience with app development myself, but maybe it would be helpful to have a look at our example apps. Source code for the nRF blinky and nRF toolbox app is available on our Github page here: https://github.com/NordicSemiconductor/iOS-nRF-Blinky

I don't have to reboot the phone, only to restart my app, then it pairs just fine. There must be a wee 'trick' on iOS to have it ask to 'pair' every time, even if a previous pairing request was rejected by the user, but I dont know what this might be!

Flicking in/out of flight mode unfortunately does not resolve.

If I use open characteristics then iOS does not ask to pair, my work around could be to do this and add application level encryption.

Hi Nigel,

I asked one of our iOS developers if they have had this problem, but they hadn't seen it before. Have you tried to enable then disable flight mode to see if it has the same effect as rebooting the phone? This is a known trick to clear cached attribute tables.

Best regards,
