RE: Problems writing/reading struct to NVS

Thanks Haakonsh.

If I simplify what I'm trying to write to NVS, it seems to work OK. I changed my data structure to just a simple array:

uint16_t lsr_strike_log[9];

And if I write/read this to NVS, I can see that the data is being stored. I'm still getting weird values for the return value from nvs_write() and nvs_read() though.

This is the log info I see when writing the simple array:

If I try and write my struct to NVS in the form I ultimately want to, I crash my DK and it keeps rebooting.

In my code I initialse NVS before I initialise anything to do with BLE, so not sure if the BLE initialisation then changes what I've done when setting up NVS?

Thanks and regards,

Mike

I think NVS might already be initialized by the bluetooth stack, it uses it to store certain settings. I'll do some digging and see what I can find.
