They can try with the nRF Connect for iOS.

It would be interresting to see whether it works on the ble_app_gls example from SDK12.3.0, vs the ble_app_gls example from SDK15.0.0 on the same version of iOS.

Hi,

Yes, your right: The customer requests encryption by writing to a protected characteristic, which then triggers an "Insufficient Encryption".

Required encryption is: unauthenticated encryption (sequrity level 1 mode 2)

I think it is related to this post in iOS forum:

They talk about a changed key calculation in firmware, but I don't know how I do that.

I can not test this with ble_app_gls example, because I don't have a related iOS app. The customers iOS app will not work with that example.

Hello,

I understand.

Just to get things straight:

You (the customer) requests encryption by writing to a protected characteristic, which then triggers an "Insufficient Encryption"?

What level of encryption does the characteristic require?

Does this happen if you try the ble_app_gls example?

Best Regards,

Edvin

The iPhone returns "Insufficient Encyption".

But it is returned by the operating system and not the iPhone application.

Hello,

What device returns the "Insufficient Encryption"? error, the iPhone application, or on the nRF side when you get the read request?

Typically, phones will request encryption when they try to access a service that requires encryption, but you should not have to disconnect and connect again for this to take effect.

But where do you see the "insufficient Encryption" return?
