BLE_NUS compatibility

I use the DK to test the code. There's a test we haven't done yet, and is now done. We tried to find tx characteristic of BLE_NUS firmware with the ioS10 compatible app. And it works! So there must be something I've done wrong when porting my firmware to the new SDK version.

Ok. Are you using the nRF52 DK when testing the code? Also, the descriptor being set to false should be unrelated to your problem. If I understand you correctly, you are able to find the TX-characteristic when using the nRF Connect for iOS, but not when you are using your own software?

I don't really understand your question. The iPhone is connected with pairing, but when the software made by the dev team ask for services, the tx uart characteristic is not found with the sdk 13.1 version.

If it can help, the developement software are Xcode 8.3.3 and swift 3. It works well with SDK09, but not with SDK13. We have inspecting everything in xcode, but it seems that the problem comes from advertising.

We've seen that descriptor in nrf connect is set to false, can it be that?

I have tested it myself with an Iphone 7 with iOS 10.2.3, and it works fine. What device are you using? Also, how are you connecting the phone to your device?

Yes, I use the ble_app_art as is from the SDK. The softdevice version is S132 4.0.2. It works well with a PC or an Android device, but not with an iOS device.

I see. Are you using the ble_app_uart example from the SDK? Which softdevice version are you using?

Hi cedric! As you might know, iOS 11 is still in beta vesion. The beta version has shown to have problems with bluetooth connections and I do believe that is where the problem is. Maybe you could provide a sniffer trace to see what happens over the air?
