CONFIG_BT_MESH_RPL_STORE_TIMEOUT¶
Minimum frequency that the RPL gets updated in storage
Type: int
Help¶
This value defines in seconds how soon the RPL gets written to persistent storage after a change occurs. If the node receives messages frequently it may make sense to have this set to a large value, whereas if the RPL gets updated infrequently a value as low as 0 (write immediately) may make sense. Note that if the node operates a security sensitive use case, and there’s a risk of sudden power loss, it may be a security vulnerability to set this value to anything else than 0 (a power loss before writing to storage exposes the node to potential message replay attacks).
