    Hi @Afomin31 , like the link shared, if have connected to module, the next need to get Service and Service's Characteristics ,

    var services = await connectedDevice.GetServicesAsync();
var characteristics = await service.GetCharacteristicsAsync();

    the info can be get form Characteristics like this:

    var bytes = await characteristic.ReadAsync();

    The last step , you need to deal with the bytes data. And the format of the data depends on the format in which the connected device is sent.
    There is a demo can be refered to.
