NRF8001 Attempting to add Custom Services

[Matthew]

Hi,

I'm using a NRF8001 shield with an Arduino Leonardo, everything connection wise seems to be working. I'm using the "ble_my_project_template" and uploading various services.h files from other demos. I can see on my iPhone that the BLE devices shows up as a temperature monitor, UART, etc.

My problem is that I have been building my own services.h file using the nRFgo Studio and it compiles and uploads to the arduino (and supposedly the nrf8001) but only the name of the device changes. The available services and characteristics do not change.

My end goal is to build a set of custom Services to allow the iPhone to connect to the ble device and read sensor data. Is there an obvious reason why I can't update the services.h? Is there some sort of tutorial for this?

Thanks,

Matt

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).

iOS Buffering was the problem. Thanks for the help!
