Regading the new MKR1310 PCB, how to use the new FLASH memory to store the network keys between poweups to avoid repeted OTAA Joins.
We run the MKR1310 on battery and when we go to sleep after our task is complete. When the device wake up again it dont remember the network keys so we need to do another OTAA join again, I would like to store the key before the device go to sleep and read them again on powerup and do a ABP join instead (read keys from memory)
We are using the sparkfun nano timer…
(SparkFun Nano Power Timer - TPL5110 - PRT-15353 - SparkFun Electronics)
We are complete newbies so plese be generous withsample code and explanation.
