How to adjust or cancel the LMIC libraries duty cycle check?

61

I looked at loramac-node, the code is almost impenetrable, clearly written for experts only.

I found this thread in here;

https://www.thethingsnetwork.org/forum/t/deep-sleep-and-otaa-m328p-lmic/27199/12

But code example does not exist anymore.

The function mentioned in MCCI_LMIC is;

LMIC_getSessionKeys() which is this;

LMIC_getSessionKeys(&netid, &devaddr, nwkKey, artKey);

The LMIC version I have used so far has access to these, printed out at join;

LMIC.netid
LMIC.devaddr
LMIC.artKey
LMIC.nwkKey

Presumably stored in RAM, so you might think its not too difficult to save them to FRAM and read back, I have done a library that read\writes the various variable types and arrays to a FRAM.

However, I suspect that storing the above in FRAM is only a part of the problem, the library may well have status flags and other counters that need to be saved ?
