You have deployed location services at a site and have installed an application which includes the Mist SDK on Bluetooth-only mobile client devices. The devices with the SDK-enabled app have Bluetooth enabled, but the devices do not appear in the Mist GUI under Clients/App Clients.
What is causing this problem?
- A. There is BLE and Wi-Fi co-channel interference.
- B. The AP BLE radios do not hear the SDK-enabled client's BLE beacons.
- C. The clients are connected to the wrong WLAN.
- D. The client devices are not connected to Wi-Fi or to a cellular data plan.
Answer: B
Explanation:
Explanation
If Bluetooth-only mobile client devices with an SDK-enabled app do not appear in the Mist GUI under Clients/App Clients even though they have Bluetooth enabled, it could be because the AP BLE radios do not hear the SDK-enabled client's BLE beacons.
According to the Mist documentation1, Mist SDK is a software development kit that enables indoor location and proximity services using Mist's virtual Bluetooth LE (vBLE) technology. The SDK allows mobile applications to communicate with Mist APs using BLE beacons that are transmitted by the client devices.
The devices with the SDK-enabled app have Bluetooth enabled, but they do not appear in the Mist GUI under Clients/App Clients because the AP BLE radios do not hear the SDK-enabled client's BLE beacons. This could be due to various factors such as interference, distance, obstacles, or configuration issues that affect the BLE signal strength and quality.
