Can't write to paired TI device on Windows 10 Creators Edition RRS feed

  • Question

  • I am trying to create an app using the TI CC260R2 device. I am able to connect to it and write to it if the device is not paired. However, as soon as I pair the device I am unable to write anything too it, even the CCFG for notifications. Every time I try to write to the device I get an unreachable response.

    Below is the code I am using to write to the device. It is from DeviceWatcher on Device added <g class="gr_ gr_24 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins doubleReplace replaceWithoutSep" data-gr-id="24" id="24">event</g> handler.

    private void WatcherOnAdded(DeviceWatcher sender, DeviceInformation args)
                leDevice = await BluetoothLEDevice.FromIdAsync(args.Id);
            catch (Exception)
                leDevice = null;
            if (leDevice == null) return;
    GattDeviceServicesResult gattDeviceServicesResult = await leDevice.GetGattServicesAsync();
    foreach (GattDeviceService gattDeviceService in gattDeviceServicesResult.Services)
        GattCharacteristicsResult gattCharacteristicsResult = await gattDeviceService.GetCharacteristicsAsync();
        foreach (GattCharacteristic gattCharacteristic in gattCharacteristicsResult.Characteristics)
            if (gattCharacteristic.CharacteristicProperties.HasFlag(GattCharacteristicProperties.Notify))
                GattCommunicationStatus gattCommunicationStatus = await gattCharacteristic.WriteClientCharacteristicConfigurationDescriptorAsync(GattClientCharacteristicConfigurationDescriptorValue.Notify);
