iOS Device show Peripheral Name as DFUTarg after Doing DFU ?

[Nik]

Hello,

I am able to get NRFtoolbox dfu code work for iOS 10.3. and now able to perform the DFU on BLE device.

But when I perform the DFU its GAP name changes from Beam to DFUTarg and it remains as it is forever until I manually reset my phone.

Is there a way to clear the BLE name cache or do I need to Implement any change at firmware end to get rid of BLE name cache issue.

Thanks In advance.

Yes, this sounds like a caching issue. If you have the Service Changed Characteristic enabled then you should see the device name updating after you have connected to the device. Which SDK version are you using to build your application and bootloader?

[Nik]

SDK version - 11.0.0 for both application and bootloader. We have already added Service Changed Characteristic and by using that we are able to get rid of the issue occur when we change the services and application need to remove cache for that.

But the problem with the name is still exist. Do we need to do some special changes in Service Changed to clear the Name cache.

No, the Device Name should be updated when the iPhone has performed a Service Discovery after the device has indicated that the GATT table has changed. Service Changed is enabled in both the application and the bootloader right?

[Nik]

Yes, We have added Service Changed Characteristic in both application as well as in bootloader mode. But still no luck on removing cache data.

It should update with out any action from you. However, could you try to read the Device Name characteristic under the GAP service manually? This could cause the Device name to update faster.
