The sniffer enable command enables and configures the working mode of an AP's built-in Bluetooth module.
The undo sniffer enable command disables the configured working mode of an AP's built-in Bluetooth module.
By default, the Bluetooth function of an AP's built-in Bluetooth module is disabled.
Usage Scenario
After enabling the Bluetooth monitoring function, the built-in Bluetooth module of an AP will scan and obtain information about surrounding BLE devices, and reports the obtained information such as MAC addresses, RSSIs, BLE broadcast frame contents, and battery power.
After the Bluetooth monitoring function is enabled, an AP obtains battery power of surrounding Bluetooth devices at WLAN service off-peak time, for example, 2:00 am of the system time. Precisely configure the system time of an AC to ensure that WLAN services are not affected when the AC obtains battery power of Bluetooth devices.
The Bluetooth broadcast and Bluetooth monitoring functions can be enabled simultaneously for an AP's built-in Bluetooth module. When the two functions are enabled simultaneously, the AP's built-in Bluetooth module is also monitored.
After you run the undo sniffer enable command to disable the BLE monitoring function, the AC will trigger an alarm indicating that BLE devices are offline.
Follow-up Procedure
After the Bluetooth monitoring function is enabled, you are advised to run the ble monitoring-list command to add Bluetooth devices to the monitoring list for easy management. When a Bluetooth device in the monitoring list is offline or has low battery power, an alarm is triggered on the AC accordingly. If a Bluetooth device is not in the monitoring list, no such alarm will be triggered on the AC.
