The first step to do this is to query for services: GattDeviceServicesResult result = await bluetoothLeDevice.GetGattServicesAsync(); if (result.Status == GattCommunicationStatus.Success) { var services = result.Services; // } Once the service of interest has been identified, the next step is to query for characteristics. The Generic Attributes (GATT) is the name of the interface used to connect to Bluetooth LE devices. The interface has one or more Bluetooth Services, identified by unique ids, that contain Bluetooth Characteristics also identified by ids. A GATT client scans for devices that are advertising, connects to a chosen server device, discovers the GATT Service: GATT stands for Generic Attribute Profile; this defines some standard ways using which two BLE devices should always communicate.

The Generic Attributes (GATT) is the name of the interface used to connect to Bluetooth LE devices. The interface has one or more Bluetooth Services, identified by unique ids, that contain Bluetooth Characteristics also identified by ids. A GATT client scans for devices that are advertising, connects to a chosen server device, discovers the services, discovers characteristics and then reads from, writes to or sets up a connection to receive notifications from the characteristic.

Anything from instantaneous to a matter of minutes. Factors inclue the traffic on the stack, and how queued up the request is.

When using discoverServices() after a successful connect, 4 services are found in the HCI log (see Wireshark screen below). But only 3 services are returned from getServices() in my own Android code and in the nRF Bluetooth app, and the third service is missing its only characteristic: The 4th service and its characteristic are nowhere to be found.
