LWM2M Carrier - How much to erase when want to re-bootstrap?

[jbrzozoski]

When I let the lwm2m_carrier library run through a full bootstrap/registration cycle on a fresh device, it generates and saves many bits of info in both NVS and TLS security slots.  If I want to go back an re-run bootstrap for carrier testing, which portions of that should I delete?

Hi!

Which version of liblwm2m_carrier are you using?

Best regards,

Heidi

I just integrated v0.8.0, so it's using NVS slots in the 0xCA00-CAFF range, and it appears have only used security slots in the 25-27 range so far.

Okay, then you will have to delete from 0xCA00 to 0xCAFF. And delete security slot 11.

You could also just erase the whole chip if you don't have any other data in flash that you want to keep.

Doing "erase all" in the programmer doesn't hit the security slots, so I'd still have to get slot 11 manually if I do that.

Thank you for the info!
