Setting up MultiTech LoRaWAN gateway on Ubuntu

As the convener for the Adelaide community of The Things Network, I am frequently setting up Multitech Conduit Gateways. Depending on your PC or notebook hardware you might have some problems with the Exar USB-UART driver on Linux. Here are the steps to getting this unit setup from an Ubuntu (should work for any other Linux distro) machine. lsusb Should show something like this: Bus 002 Device 006: ID 04e2:1410 Exar Corp. XR21V1410 USB-UART IC Download the driver for the Exar site: https://www.exar.com/design-tools/software-drivers unzip xr_usb_serial_common_lnx-3.6-and-newer-pak.zip cd xr_usb_serial_common_lnx-3.6-and-newer-pak make sudo insmod ./xr_usb_serial_common.ko Ensure driver is loaded at startup sudo vim /etc/modules #Add the following xr_usb_serial_common ls /dev/tty* should now show another USB port ttyXRUSB0 For the rest you just need to follow the excellent instructions by Jac Kersing who maintains the Multitech TTN installer and documentation here: https://www.thethingsnetwork.org/docs/gateways/multitech/mlinux.html Get EUI of your gateway mts-io-sysfs show lora/eui 2> /dev/null | sed 's/://g'

Connecting your LoPy to The Things Network in Australia

EDIT [2018-06-05]: I have updated the code with the Firmware 1.18.+ releases. The code is available at our Growing Data Foundation Github. These notes are to assist Australian IoT enthusiasts to get started in connecting a LoPy to The Things Network as it is unfortunately (not yet) straight forward to make them work with the current AU-915 TTN Channel plans. As the initiator of the local Adelaide Community of The Things Network I have been experimenting with a number of devices to connect sensors to #TTNADL. One of my personal favourites is the Pycom LoPy as a nice middle-ground between capabilities and technical complexity. However I ran into a problem where the LoPy would not get a signal back from the TTN network when joining over OTAA even though the TTN Console (http://console.thethingsnetwork.org/) the device showed as connected. With some friendly help from Jose Marcelino at the Pycom Forum this turned out to be an issue with the 915MHz frequency regions. Since there is no actual a standard governing which of the channels are used by TTN gateways, what is outlined here is what is implemented by most TTN communities down under (I know that at least ADL, BNE, SYD and WOL adhere to those). This is the typical Sub-band 2 (Channel 8-15) implementation of AU ISM 915 with TTN Gateways. This channel plan is also implemented by the install script for the MultiTech Conduit Gateways which are currently the most common gateways installed across Australia (see https://github.com/TheThingsNetwork/gateway-conf/blob/master/AU-global_conf.json) Channel#DirectionFrequency MHzBandwidth…
