5.4 Bluetooth Broadcast Capabilities
LW001-BG PRO has two Bluetooth broadcast modes: Beacon mode and Configuration mode，
which can be switched by users.
5.4.1 Beacon Mode
The LW001-BG PRO will always broadcast Bluetooth information in Beacon mode, and users can
use the LW001-BG PRO as a beacon device to do Bluetooth positioning and other application
development.
When the device is in Beacon mode, the user can choose to leave the device in a connectable or
non-connectable state, considering that it prevents strangers from being able to establish a
Bluetooth connection with the LW001-BG PRO at will.
Connectable state: The device is always available to be connected by the host.
Non-connectable state: Bluetooth broadcasting will always be going on, but only within 3 minutes
after the product is turned on, the user can use the host device to establish a Bluetooth
connection with the LW001-BG PRO.
Note: When the device is in beacon mode, considering the performance of both broadcasting and
scanning cannot be taken into account, the Bluetooth positioning function will not work properly,
and if Bluetooth positioning is performed at this time, it will be directly judged as failure.
5.4.2 Configuration Mode
When Bluetooth broadcast is in configuration mode, the device can make a Bluetooth broadcast
and can be connected in the following two cases.
1. Within the first N minutes after the device is turned back on.
2. LoRaWAN server sends LoRa command to turn on Bluetooth broadcast for N minutes.
Note: N is the configuration mode broadcast timeout time, can be configured by the user. If the
device is successfully connected and then disconnected, the broadcast timeout will be refreshed,
and the user can choose to establish Bluetooth connection with the device again within this time.
