when I debug the LPN,I have some doubts about LPN sleep times. the print messages as below:
before establishing the friendship with the friend node, the sleep timeout is 8s, after establishing the friendship, the sleep timeout is 6s
the device configuration info is 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 = 3, // 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 = 100 // Poll timeout in 100ms units to be requested by the Low Power node.
hope for correct reply as quickly as possible!
