I am struggeling with a handful of problems. Slowly but securly the fun with this project tranforms into sadness. But enogh complaining for now. Let me describe you some of my problems:
I own a gateway, connected to TTN. It is a Dragino LPS8, placed on my roof with a RAK Antenna.
It is the only gateway in the area.
One of my nodes is a Stemedu Lora Node 1.0. I am running it with the ABP-example-Sketch. Now the strange thing comes into play: The message sent from the node is seen by the gateway (I see it in the TTN console). But somehow it is not linked to the device of my application. After some days of running it will suddenly work. It also works instantly if I leave the area of radio reception and come back. The message will be linked to the device from the first message on. BUT: If I reset the device I have the same problem as in the beginning - The gateway sees the messages from the node but there is no link to the device. And again after some days it will work.
If I take it with me and drive to another city with another gateway it will also work. If I come back to my gateway it works too. If there was no reset…
I don’t understand this.
Furthermore I have problems with my heltec esp32 Lora Node in OTAA. The gateway sees the join request, the gateway accepts this, but nothing happens. Sometimes it works. But most time it dont.
At the moment the node is 10m from the gateway. The rssi received by the gateway is -46 with a snr of 7.8 and a SF of 7
If it is working I have a range of up to 7km around my gateway. So signal strength should not be a problem.
Do you have any ideas?
Thank you very much.
