Raspberry Pi image generator for LoRa Server


Using the script which you can find here: https://github.com/brocaar/loraserver-pi-gen, you can generate a Raspberry Pi image with the Semtech packet-forwarder and all LoRa Server components pre-installed (including dependencies) :slight_smile:

This could be useful when you have a Raspberry Pi based gateway, and want to run the full stack on the Pi.

Note: You don’t (have to) execute the script on a Raspberry Pi!


I will like to know if this includes gateways built of Raspberry PI + Dragino Lora GPS HAT?
I know it is not a full gateway, but I am using in the context of school research. I would like to run the Lora Server Locally, but it is somehow difficult to install. Is it possible?
Thanks in advance.


I have to add that, I already have a packet forwarder adapted to my setup and the can connect to a TCP / UPD server and send and or receive data. I need this because I don’t want to implement all the security and node identification related functions myself.


Basically it installs the Semtech packet-forwarder + all LoRa Server components and requirements. You can always make modifications afterwards if needed or install additional software (e.g. if needed for your Dragino gateway) :slight_smile:


Hi @brocaar,

Thanks for the fantastic work done here!

I am getting the following when using docker to get the image installed on my Raspberry Pi.

[09:29:51] End /pi-gen/stage3/03-loraserver-deps/01-run.sh
[09:29:51] End /pi-gen/stage3/03-loraserver-deps

I managed to get it installed using ./build.sh (without docker) yesterday and got the .zip image in /deploy. I had to format my SD and lost progress. I am trying again now both methods are not working. (I had previously installed TTN related stuff which maybe might have already installed those packages?)

Also when I get the .zip image how do I mount it? I am not too familiar with the technical steps… but from what I understand I should be able to copy it on my SD and use NOOBS to mount?

Any advice would be appreciated.


Hello again,

I successully get the .zip image when I install this:

$ git clone -b spi https://github.com/ttn-zh/ic880a-gateway.git ~/ic880a-gateway
$ cd ~/ic880a-gateway
$ sudo ./install.sh spi

Done! Your image(s) should be in deploy/

I noticed the install creates a new user pi@ttn-gateway. In any case I am still confused as to what to do with that .zip image.

Please help. Thanks.
