i am using RAK4270 on the RAK Breakout Board with the latest firmware and try to figure out how to set the sleep mode to save battery.
The device works great, uplink, downlink everything is perfect.
When i send the
I always get ERROR:80 (device busy)
What are the requirements for the sleep mode?
Here is the output of the RAK Serial Port Tool:
OK RAK4270 v18.104.22.168
Maybe i have wrong understanding from the sleep command.
Many thanks in advance for your help!
