LR1262 - AT+JOIN after each power up?
Hello,
I have been trying to use LR1262 Lora module (the one with integrated MCU) to send messages to my LR1302 Gateway. I can join network and see my payload in TTN Console after AT+SEND.
When I power on my LR1262 and run AT+RESET i get my module default NwkSKey. If I run AT+JOIN=1,1 and it succeeds AT+NwkSKey=? returns new key. I then run AT+SAVE to save session keys.
I would assume after powering off and on I don't have to AT+JOIN again since my session keys are saved.
I checked with AT+NwkSKey=? and indeed, correct session key is saved.
However if I run AT+SEND=1:1:11 i get "ready to send data \r \r AT_BUSY_ERROR"
I can't manage to send data if I dont run AT+JOIN again.
Do I need to JOIN after each power up?
Is there some other command i need to run after power up before I will be able to send data?
