Indeed, they are.

Thanks for your reply - I am going to create my own mechanism to change the device name.

Greetings,

David

hmm, as far as I know it has newer been possible to change the device name for a Bluetooth LE device from iOS. Your soundbar and headset are likely BR/EDR devices?

Hi run_ar,

Thank you for your quick response!

I know that iOS is filtering out the above mentioned services, so I don't have access to them from my app. That's the reason you can't use nrf Connect to change the name since it simply has no access to the GAP characteristics.

Instead I would like to use the integrated mechanism in iOS:

When you go to "Settings" -> "Bluetooth" then there is the list of known devices. If the device was bonded to the phone then there is a little "i"-Button attached to the entry. Tapping this little icon will lead you to the device settings. And in the case of my soundbar or my headset I can actually change the name of the device.

The big question is: if GAP is implemented correctly and the Device Name Characteristic is writeable, will iOS offer me to change the name or not. Or is this only possible with other Bluetooth Protocols.

If that's not possbile I am going to implement it in the app via my own settings characteristic. But in the first place I would like to use the "standard way" or "native way" of changing the device name in iOS.

Thanks and have a good Day!

David

Hi,
I did a quick check using the blinky peripheral application from our SDK. Using nRF connect on windows I was able to update the device name. However using nRF connect on iOS I was not able to update the device name. As far as I know it is not possible to write to the device name from iOS, but it's been quite some time since I last checked. Still thinking it is the case, based on this from the accessory design guidelines:

When third party iOS applications discover services on the accessory, the following services are usedinternally by iOS and are filtered out from the list of discovered services:

●Generic Attribute Profile Service

●Generic Access Profile Service

●Bluetooth Low Energy HID Service

●Apple Notification Center Service

Also the code from the blinky example is similar to yours

static void gap_params_init(void)
{
    ret_code_t              err_code;
    ble_gap_conn_params_t   gap_conn_params;
    ble_gap_conn_sec_mode_t sec_mode;

    BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);

    err_code = sd_ble_gap_device_name_set(&sec_mode,
                                          (const uint8_t *)DEVICE_NAME,
                                          strlen(DEVICE_NAME));
    APP_ERROR_CHECK(err_code);
