90.4	199	The SDI-12-LB/LS is configured as (% style="color:#037691" %)LoRaWAN OTAA Class A(%%) mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and activate the SDI-12-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

2.2	1125
	1126	These commands are to configure:
	1127
	1128	* General system settings like: uplink interval.
	1129	* LoRaWAN protocol & radio related command.
	1130
	1131	They are same for all Dragino Device which support DLWS-005 LoRaWAN Stack. These commands can be found on the wiki:
