Function Documentation

void LMIC_setSession ( u4_t  netid,
devaddr_t  devaddr,
xref2u1_t  nwkKey,
xref2u1_t  artKey 
)

Setup given session keys and put the MAC in a state as if a join request/accept would have negotiated just these keys.

It is crucial that the combinations `devaddr/nwkkey` and `devaddr/artkey` are unique within the network identified by `netid`. NOTE: on Harvard architectures when session keys are in flash: Caller has to fill in LMIC.{nwk,art}Key before and pass {nwk,art}Key are NULL

Parameters:
netida 24 bit number describing the network id this device is using
devaddrthe 32 bit session address of the device. It is strongly recommended to ensure that different devices use different numbers with high probability.
nwkKeythe 16 byte network session key used for message integrity. If NULL the caller has copied the key into `LMIC.nwkKey` before.
artKeythe 16 byte application router session key used for message confidentiality. If NULL the caller has copied the key into `LMIC.artKey` before.
