I made a duplicate sd (and some backups) and stopped the Loriot gateway after booting the duplicate.
There was no uninstall.sh although they mentioned it.
I manually moved/renamed the /opt/lrt and rebooted.
The TTN gateway was easy to install with the link you provided.
I can swap the sd cards now to choose the network Loriot or TTN.
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.
