whats your aerial setup? aerial type/cable type/cable length/inline adapters?

@ the moment a typical indoor GP living room set up
Yes I think a GP will give a better result (indoor/outdoor) then the supplied antenna … but I use the GP only for testing, I have an outdoor antenna.
would you get the same distance from the RAK supplied aerial?
Do you know which lora gateway board support LBT?
I am using the 915Mhz version, with TTN P.F. I have managed to make it work, but only for a few hours, now looks like it is connected in TTN but it does not receive the packages, also notice that the LED RX no longer lights, I will try leaving it off for some time to see if it is a problem of temperature or voltage, which are the two topics I have read may be the cause. Additionally, could anyone confirm if (–reset-pin 25) actually works?
It works for me! (mind you, this is pin 22 on the GPIO header!)
I noticed the temperature of the RAK pcb after 30 min, could it that the RPI is heating the RAK831 when you use a converter PCB ?
That is a fairly normal temperature for a concentrator board. The MultiTech mCards are at finger burning temperature when used with an PCIe-to-USB convertor. Other concentrators are also well above room termperature in my experience.
So (imho) nothing to worry about.
I’ve the same problem with my 868MHz board. After few hours it stops receiving packets. When I restart ttn packet forwarder it start working. Packet forwarder makes the board reset (pin 25).
I have the RPi and the RAK831 in a “RPi casing”.
The CPU core temperature was in the 55-65 degrees range and the RAK831 got warm (I would not say “hot”).
Now I have added a small Cooling Fan that blows at the back of the RAK831. The CPU core temperature is now in the 30-35 degrees range. I have no way of measuring the RAK831 but I expect it to run cooler also.
It was a web shop in the Netherlands. (SOSsolutions maybe, I’m not sure) but they don’t sell them anymore. The casing is build with a bottom and a top and in between you can add 1, 2 or 3 fillers.
I’m searching for a tall case to
found this one https://www.modmypi.com/raspberry-pi/cases-183/highpi/highpi-raspberry-pi-b-plus2-case
or, if you have a 3D printer https://pinshape.com/items/22512-3d-printed-tired-cube-raspberry-pi-3-case
I too am trying to gt 915 to work. I don’t think I have a good global_conf.json. I have been able to get a node to send data to the rak831 if I disable crc, but then the data is junk. Have you had any progress?
can you post your RAK startup log and json config?
global_conf.json for 915MHz …maybe

With ttn packet forwarder RPi3+RAK831 only works if I run the command manually every time it is restarted, I’ve been testing this way for several days and it’s still working, but I have not been able to run as service (install-systemd.sh script does not seem to work) to start automatically.
Hi (just breaking in your conversation with @meldundas),
I’m using the TTN Packet-Forwarder. Seems to work OK, but I don’t have a json config file.
Is that normal for my gateway?
Are you running Jessie? Older versions of Rasbian did not use systemctl…
If Jessie, did you “systemctl enable ttn-pkt-fwd.service”?
