Configure your gateway in order for it to gain internet access and finally run the following (using the correct region file):
mkdir /user/resiot cd /user/resiot wget https://update.resiot.io/bsclient/resiot-basestation-client-KIBTS-EU_863_870.ipk mkdir -p /user/.updates mv resiot-basestation-client-KIBTS-EU_863_870.ipk /user/.updates/

Customizing the firewall¶
The IBTS comes with a built-in firewall. The Merlin setup package will install some premade firewall rules to make sure everything works correctly between Merlin and ResIOT.
If you have a custom ResIOT build running over non-default ports, you might need to edit the default rules that came with the script. To do so, edit the file
/etc/firewall.d/resiot.rules and change the default ports with the ones your setup is using instead. Here are the default ports in your file and what they refer to:
[OUT] 7677 udp: LoRa communication [OUT] 8095 tcp: default ResIOT gRPC connection [OUT] 1883 tcp: default MQTT broker connection [IN] 50056 tpc: default Merlin webserver [IN] 50076 tpc: default Merlin Update webserver
Shall you want to uninstall Merlin, just run the following commands:
rm /etc/rcU.d/*resiot* rm -r /user/resiot rm /etc/firewall.d/resiot.rules reboot
After the reboot, your ResIOT™ BaseStation Gateway Client will be installed and running. Refer to the official ResIOT website for further instructions.
