We have 3xRAK185 tracker (with module 813) and 1xPilot Gateway.We have edited the software to send GPS or BLE data over LoRa. Now we are trying to send GPS data over Lora (868Mhz). All of the trackers find GPS but only one of them is sending data to LoRa Gateway (Pilot Gateway). All ol them have the same software and have same conditions (they are in the same place). We have tried to use them one by one, but only one tracker send data to Lora Gateway again. We use different LoRa gateways but the result was same.
After a lot of unsuccessful tries, we found something. We saw that the tracker send LoRa packets when we made compression (hardly) on the Lora module on it. I think there is a connection problem on it. We tried this solution on the other non-working tracker, result is the same, Worked!
5-10 mins after compression, the problem appeared again…
We have ordered them 2 weeks ago for testing and they are already new.
Do you have any idea to solve this problem?
Thanks for your helps
