Install the TTN Packet Forwarder on a Multitech Conduit

Note: if you're using an AEP model, you will need to configure the Conduit on the web interface before installing the Packet Forwarder. Consult this guide to learn how to do this.

Download and install

Note: Before installing the new packet forwarder, make sure you removed any other packet forwarder installed on your Multitech Conduit.

  1. Download the Multitech Conduit package of the packet forwarder.

  2. In the archive, you will find an create-package.sh file, a multitech-installer.sh, as well as the executable binary. Execute the create-package.sh file, with the binary as a first argument:

$ ./create-package.sh <packet-forwarder-binary>
[...]
# Following the instructions of the wizard
./create-package.sh: package available at ttn-pkt-fwd.ipk
  1. Copy the package on the Multitech Conduit, using either a USB key or scp if you have an SSH connection to the Multitech Conduit. Install the package, configure the packet forwarder, then start it:
$ opkg install ttn-pkt-fwd.ipk
Installing ttn-pkt-fwd (2.0.0) to root...
Configuring ttn-pkt-fwd.
$ /etc/init.d/ttn-pkt-fwd configure
[...]
# Following the instructions of the wizard
  INFO New configuration file saved             ConfigFilePath=/var/config/ttn-pkt-fwd/config.yml
$ /etc/init.d/ttn-pkt-fwd start
Starting ttn-pkt-fwd: OK

Build the TTN Packet Forwarder for the Multitech Conduit

If you use a specific machine or want to contribute to the development of the packet forwarder, you might want to build the TTN Packet Forwarder. You might need to use a Linux environment to run the toolchain necessary for the build.

Downloading the Multitech toolchain

To build the packet forwarder, you will need to download Multitech's C toolchain. Download it, and install it by following the instructions on Multitech's website.

Building the binary

  1. Download the packet forwarder, along with its dependencies:
$ go get -u github.com/TheThingsNetwork/packet_forwarder
$ cd $GOPATH/src/github.com/TheThingsNetwork/packet_forwarder
$ make dev-deps
$ make deps
  1. Enable the Multitech toolchain, then set those environment variables:
$ source /path/to/sdk/environment-setup-arm926ejste-mlinux-linux-gnueabi
# Usually /opt/mlinux/{version}/environment-setup-arm926ejste-mlinux-linux-gnueabi
$ export GOARM=5
$ export GOOS=linux
$ export GOARCH=arm
$ export CFG_SPI=ftdi
$ export PLATFORM=multitech
  1. Build the binary:
$ make build

The binary will then be available in the release/ folder.

Building the package

To build the package, use the scripts/multitech/create-package.sh script:

$ ./scripts/multitech/create-package.sh release/<packet-forwarder-binary>
[...]
# Following the instructions of the wizard
./create-package.sh: package available at ttn-pkt-fwd.ipk

The package will then be available at the specified path.
