4.1.1 BDB Initialization

The BDB initialization procedure defines the behavior of a device on initialization/Reset. As a first step, the device restores all its persistent data. Then, the further steps can vary depending on the logical device type and whether the node is already part of a network.

• If an end device is already part of a network, it tries to rejoin its parent.
• If a router is not already part of a network, it chooses a logical channel from one of the available channels in the APP_PRIMARY_CHANNELS_MASK.

If neither of these cases applies, the device moves straight to commissioning. The application must initialize the BDB layer before it can access any BDB APIs.

The application can invoke BDB initialization using the following public API:

void BDB_Init(void);
