Wb55 - otThreadGetMeshLocalEid return value changing

Hi,

I'm currently using a custom board containing a WB55 chipset. My application running on this uses the Thread (open thread) FTD firmware (v1.23.0.0)

 

My understanding is that given a fixed mesh local prefix calls to otThreadGetMeshLocalEid should return a consistent value through reboots.

 

This does not seem to happen as otThreadGetMeshLocalEid returns a different address each time. Note, thread starts and is usable I'm just not getting a stable address. I'm not using COAP - straight Thread (not Matter) and I can get communication across the network so my basic setup is ok.

 

Information on this subject is scarce and sometimes vague. Can you clarify - Should otThreadGetMeshLocalEid return a stable address across reboots. I'm not able to upload my source.

Cheers

Andy
