Martijn, Thanks for the follow-up. I believe that the firmware had not correctly implemented the module vendor’s API for sending an indication on Service Changed. I worked with our firmware engineer and the vendor’s field application engineer to correct the implementation and now the Core Bluetooth didModifyServices: API is being called as expected when the GATT database is changed on the peripheral. Cheers! -robret

Hi Robert,

Yes, we're seeing that method getting called when our (bonded) device sends a value update indication for the "Service Changed" characteristic with the handle range that has changed (only send it after iOS has subscribed to it). iOS will then perform a service discovery and call that method as a result.

We’re confirming with the module vendor that it correctly implements the Service Changed characteristic. Using the vendor’s (Windows-based) tool, I can see that the Service Changed characteristic is visible.

The only mention of didModifyServices: in a cursory search of the bluetooth-dev archives is below, but it’s light on details: http://prod.lists.apple.com/archives/bluetooth-dev/2015/Feb/msg00004.html

Has anyone successfully gotten a callback on the didModifyServices: method (using a non-iOS peripheral)?
