LoRaWAN Session keys store is already working on V2.1.0 ?

[DPrie.1]

Hello everybody,

I'm using the AT code modified in order to join my own server with an OTAA configuration in a solar application, so every morning the system goes up, and late afternoon the system shuts down.

I want to store session keys, counters and all stuff necesary for not rejoining server each time a power down/up is done.

CONTEXT_MANAGEMENT_ENABLED is defined to 1, and I needed to add some libraries related to nvm (NvmDataMgmt.c/.h and nvmm.c/.h).

When firmware enters in LmHandlerConfigure(), I receive a "Restored", showing that we are here:

 // Restore data if required
 nbNvmData = NvmDataMgmtRestore( );
 
 // Try to restore from NVM and query the mac if possible.
 if( nbNvmData > 0 )
 {
 	MW_LOG(TS_OFF, VLEVEL_M, "###### RESTORED\r\n");
 CtxRestoreDone = true;
 }
 else
 {
 	MW_LOG(TS_OFF, VLEVEL_M, "###### NOT RESTORED\r\n");
 CtxRestoreDone = false;
 }

However, I try to send a message without doing a AT_JOIN and always returns AT_BUSY.

Need to send some special AT command before start sending messages? Or maybe the keys are not restored correctly?

Thank you very much!

Regards,
