In this mode, the end node will send a Join Request to server, server will reply with a Join Accept and the end node will parse this Join Accept message to get the Dev Addr / APP Session Key(AppSkey / Network Session Key(NwkSKey). Because the AppSkey and NwkSkey is dynamic, OTAA mode provide more security. 51 -* ABP: Activation by personalization. There is no hand-shake with LoRaWAN server for activition. The end node will use fix Dev Addr / APP Session Key(AppSkey / Network Session Key(NwkSKey) to upload the packet. So the packet can be decode if someone know these fix keys .51 +* ABP: Activation by personalization. There is no hand-shake with LoRaWAN server for activition.

Add decode program and add the keys of the sensor. So to get the payload. There is an example for such application, see [[Communication with ABP End Node>> doc:Main.Communicate with ABP End Node without LoRaWAN Network Server --- LG308.WebHome]]60 +1.

Use an unencrypt firmware = 63 63 64 64 If user doesn't care about the security of the data and use Dragino end node, it is possible that we provide a firmware without AES128 encrytion, so the server no need to decode packet. Please note this software is no LoRaWAN compatible and no security.
