iOS Buffering was the problem. Thanks for the help!

On a more basic level, make sure your new services are added to nRFgo's "Local (GATT Server)" column and not the "Remote (GATT Client)" column. It originally didn't occur to me that I could be specifying services that the nRF8001 wouldn't itself be providing, so the distinction was lost on me the first time I did this.

You can use the nRFgo studio version 1.16.1 to add the Service Changed Characteristic in nRF8001 Configuration -> GAP Settings -> Advanced GATT Settings Select the option "Add Service Changed Characteristic".

Otherwise you can switch off and on Bluetooth as RS above suggested and it should update the cached Services and Characteristics.

Additionally when you are using the nRFgo studio to build your services and characteristics, remember to run the run_me_compile_xml_to_nRF8001_setup.bat to convert the xml file from nRFgo studio to the services.h and services_lock.h OR use the nRFgo studio -> Generate Source files -> Generate only services.h

Let me know how it works for you.

Hi,

It could be that iOS is buffering the services and characteristics of your device and therefor does not perform a service discovery when you reconnect, despite the fact that your device has changed it's name. As far as I have seen you can force iOS to perform a new service discovery by turning ble off/on. Another option would be to add the service changed characteristic. If this is present iOS will do a new service discovery (Note that you will have to turn ble off/on the first time you connect to the device after you add this characteristic).

Regards,
