I am an student doing research on Lora Mote.
I have also get a lora Gateway device which is indoor currently.
I first program the Mote with the GUI of "LoraMacConfig". The Lora device is found by KPN wlogger.
The spreading factor is 9.
Afterwards, I use the program "LoRa_Keil5LoRaMac-node-masterKeilLoRaMoteLoRaMacclassA"
downloaded fromthe website GitHub "LoRa

The LoraMote works not as stable as prorammed with LoraMacCofig. The spreading factor drops mostly to 12 and some times recovered up to 7.
In the attached the photo show the behaviour difference.
Anyboday has some idea how this difference is caused? Is there a way to improve the Mote behavior with the classA code?
Thank You!
