Hey there!
I am using the Arduino MKRWAN 1310 to monitor the humidity of a terrain and irrigate when needed, but I'm experiencing some difficulties when it comes to sending the data over to The Things Network.
The sending itself is fine, but I have realized that the MKRWAN library defaults to using SF12 to connect which is less than ideal because it uses the most airtime.
The only "solution" I have found to this is to restart the Murata chip before setting the data rate for every connection attempt, which is subpar.
