The Bluetooth service Characteristic on the PC cannot be obtained

[stars]

Hi

Develop environment Win10 .Net4.7.2，Chip is 52832. BluetoothLE already connected, but I can not find custom Characteristic by  BLEGattService.GetCharacteristicsForUuidAsync(UUID), it always returns null. It works perfectly on Android and iOS。Here are the service Characteristic found on the mobile side：

However, it is always unavailable on PC, and I use the Bluetooth that comes with the computer. Could you give me some suggestions on how to solve this problem?

Best regards，

Hello,

It may be that what you are seeing is that the computer has cached the Bluetooth Services when your DK was running a different application, and it doesn't do a new service discovery.

What you can do to check whether this is actually the case, is one of the following:

1: Delete the cached services from the computer (I don't know how you do that, unfortunately).

2: You can test it on a different DK (which would have a different BLE address, and hence the computer will treat it as a new device and do a new service discovery).

3: If you don't have another DK, you can try to manually set a different BLE address in your application. What SDK version are you using? If you let me know, I can help you change the BLE address of your DK.

4: You can test on a different computer, which has not cached the BLE services of that DK yet.

Best regards,
