mesh sequence number reaches FFFFFF

[William.wei]

hi Support team,

Customer tested mesh SDK4.2, and now had one question:

their product is end node, and once button pressed, MCU is waked up and  send the message to server.which looks like ----reset and button press.

after a long time, find out the sequence number reaches 0xFFFFFF, and net_state_seqnum_alloc api will return NRF_ERROR_FORBIDDEN as below.

Even after reset, it still fails, how to solve this problem.

Regards,

William.

Just remember that with smaller value of NETWORK_SEQNUM_FLASH_BLOCK_SIZE will result in a reduced lifetime for the flash. As mentioned this value shouldn't be much bigger than a value that you expect to be used up as one approaches the next reset.
