Description

Mesh stack delay work API is limited to a maximum delay of 42949672 milliseconds. (uint32).

Details

When using mesh stack API _k_delayed_work_submit_ to schedule a delayed work,

the timeout time is limited by the following value: 42949672 milliseconds (maximum value of uint32),
due to a limitation of the TIRTOS Timer API that uses UINT32 value.

This has some implications on the mesh stack behavior.

An example would be of the following scenario:

When a node (other device) subscribes to receive a periodic heartbeat message from our device, it may configure the period value to be at a range of 0 - 65536 seconds. 

Due to the given limitation, any period value in the range of 42949 - 65536 seconds, will be converted to 42949 seconds.

This limitation is driven by the internal timers API.
