now I am not very clear about that how the LPN device is to be added into the Bluetooth mesh networking. as we know, the LPN device must need a friend node
to communication with other devices. now the LPN how to choose the networking friend node device. if the provisioning procedure of the LPN device requires the participation of the friend node.
now I download the mesh provision client firmware into the CYW20735Q60EVB-01 board and use the mesh client control to create a Bluetooth mesh networking.
I add a dimmable light device into the networking. the dimmable light can be controlled by mesh client control. finally I configure the mesh light ctl server to LPN node
the configuration as below:
.features = WICED_BT_MESH_CORE_FEATURE_BIT_LOW_POWER, // A bit field indicating the device features. In Low Power mode no Relay, no Proxy and no Friend
.friend_cfg = // Empty Configuration of the Friend Feature
.receive_window = 0, // Receive Window value in milliseconds supported by the Friend node.
.cache_buf_len = 0, // Length of the buffer for the cache
.max_lpn_num = 0 // Max number of Low Power Nodes with established friendship. Must be > 0 if Friend feature is supported.
.low_power = // Configuration of the Low Power Feature
.rssi_factor = 2, // contribution of the RSSI measured by the Friend node used in Friend Offer Delay calculations.
.receive_window_factor = 2, // contribution of the supported Receive Window used in Friend Offer Delay calculations.
.min_cache_size_log = 7, // minimum number of messages that the Friend node can store in its Friend Cache.
.receive_delay = 100, // Receive delay in 1 ms units to be requested by the Low Power node.
.poll_timeout = 10, // Poll timeout in 100ms units to be requested by the Low Power node.
.startup_unprovisioned_adv_to = 128 // Interval in seconds of the advertisments of unprovisioned beacon and service on startup. Value 0 means default 30 seconds.
when I want to add the device into the networking. the mesh client control output print messages is below：
it seems the provisioning procedure is failure, now I don't know how to solve this problem !
