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: unzip 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: Get EUI of your gateway mts-io-sysfs show lora/eui 2> /dev/null | sed 's/://g'

Microchip LoRaWAN Development Utility on Ubuntu

Having just wasted a few hours on getting this Java software running on Linux I am documenting this for future reference and hopefully saving other LoRa / TTN folks some time. Prerequisites Install a Java JDK + JavaFX. This should work with the default OpenJDK 8 or 9 which comes as part of the Ubuntu repositories. I ended up installing Oracle JDK 8 as well as I thought the error might be related to OpenJDK. sudo apt install openjdk-8-jre-headless openjfx Download & install utility Download location: LoRa® Technology Evaluation Kit cd ~/Downloads/ chmod +x ./ Fix User Preferences This step is required for the Utility to run. Unfortunately, this is documented NOWHERE... Change the following files to include the FilePath entry. The map is empty by default. /home/USERID/.java/.userPrefs/dfu/prefs.xml /home/USERID/.java/.userPrefs/fed/prefs.xml <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!DOCTYPE map SYSTEM ""> <map MAP_XML_VERSION="1.0"> <entry key="FilePath" value="/home/USERID/"/> </map> If you chose the default install location you can now start the utility java -jar ~/Microchip/LoRaSuite/Applications/LoRaDevUtility/LoRaDevUtility.jar A big thank you goes to The Things Network user JBI - who provided this answer in a TTN forum post. No thanks to Microchip as their forum and firmware release policy is a bit of a shocker. There are several reports of such problems in the forum with no answers. Unfortunately, this seems to be no exception with electronics manufacturers (Hello Kerlink!).

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 ( 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 Channel#DirectionFrequency MHzBandwidth…
