2. Insert SD card into a computer and load your [wpa_supplicant.conf] into boot if you are using wifi, and drop in a [direwolf.conf](files/boot/direwolf.conf) with your callsign and password. You can use any custom direwolf config file here, enabling many different hardware configurations!
3. Insert into a raspberry pi with RTL-SDR plugged into USB, and power up! If everything was configured correctly, in about 5 minutes you should see it pop up on [aprs.fi].
Once the pi is running, it should be available on your network with hostname `aprs-pigate` and accessible via SSH `pi@aprs-pigate` using the default raspberry password. It is a good idea to change this once logged in, or disable passwords altogether and use SSH keys, which you can do by modifying the `user-data` file accessible on the boot partition after flashing.
The startup script creates a `screen` and executes the startup script [`pigate-start.sh`]. If at any time you want to explore the logs, you can ssh into your pigate and run the command `screen -r direwolf`. CTRL+C to leave the screen.
Logs are also written to `/home/pi/aprslogs/aprs.log`. You can view these with commands like `less` or `tail`, and generally may be easier to work with than the direwolf screen.
If you are setting up a digipeater, you can disable the Software Defined Radio by creating an empty file `DISABLE_SDR` and placing it into the boot folder of your SD card along with `direwolf.conf`. See the [`pigate-start.sh`] startup script for more details.
- [`packer-build-arm-image`] in this repo I use the public docker image, but you can checkout this repo if you need to customize the build environment and build a custom docker image
- [`flash`] I use this to set a custom hostname on each flash, and is what is referenced in Makefile. However, you can flash the images using any conventional method.
Run `make build` to start building your first image.
