I'm very sorry, based on the information you are currently providing, I can't tell you what is wrong with you. Let's sort out:
1.What frequency band equipment are you buying?
2.Did you configure it successfully? Is the global_conf.json file replaced by the 915 configuration? 3.Is your node 915 frequency band?
4.Maybe you should restart your TTN.
Yes, resetting the 831 should do the trick. I found out that in start.sh which is called during system startup (systemd ttn-gateway.service) this is actually done before starting to talk to the device. The problem was that this script uses RPI GPIO pin 22 but the converter board which is part of the starter kit uses pin 17.
Unfortunately I could not find any documentation for the converter board and I saw the information concerning pin 17 as a side remark in one of the tutorials.
Once changing the pin configuration now the board heats again and it connects to ttn after each reboot as expected. Communication with the WisNode also works fine.
Thanks for your help
Can you remove/ cut one side of strip? Why we don’t remove because heat sink is same dimension of entire converter board but can’t fit inside enclosure! If you buy enclosure, you just need remove one side strip and don’t put heat sink on top! We have another thermal filter for you.!
In addition, to help you cut the one side strip, Pls use tweezers and cutter to remove one side strip,passed cutter over border to make it easier to snap, and snapped it with tweezers. the tools we recommend to use below one
@audorva Well, that's not too easy to answer. If you got a good rssi (singal strength) but much noise (low snr), you won't receive anything. Same if you got no noise (good snr) but the signal is too low (bad rssi). You can look at the link budget for a hint.
