The LoRa Radio Node is an AVR Arduino board with a RFM95 LoRa module. This all-in-one LoRa module allows to have a LoRaWan device for a reasonable price around 15€. You need to add a battery (like a LS14500 3,7V battery) on the battery holder for a 4€ extra cost to make it mobile. LiPo option are also available using the power connector. Even if the connectors are looking like grove, they are not compatible so you will have to make your own wiring to connect extensions.
This post is reviewing how to getting started with this board to fire your first LoRaWan frame over The Things Network.
There is actually no solution to get an alarm when a TTN gateway is shutting down. That said, all the information are accessible thanks to the different API.
To monitor my deployed gateways, I’ve made a little script in python working with IFTTT. It connects to the The Things Network api, get the gateway status and call the IFTTT webhook in case of last gateway update too old.
On IFTTT i’ve created an applet to generate a Push notification on phone to get the alarm.
The Laird Sentrius LoRaWan gateway is a low cost, stable and easy to configure on The Things Network gateway. They are indoor gateway. I want to install it outdoor to offer a better coverage.
In certain situation the easiest way to install it outdoor is to use an external antenna and a long antenna cable. In some other situation this approach is complex to implement and the easiest way is to install the gateway outdoor with its antenna and network connection.
The best is to use an outdoor LoRaWan gateway. The price is usually > 600€. Even if in general the outdoor gateways includes GPS and Cellphone connectivity. In this post I’ll explain how I make one of Laird Sentrius outdoor because it costs less than 250€ for the gateway itself.
The HopeRF RFM95w module proposes to access LoRa at low cost. Its unitary price is around 4€ on shop like aliexpress. A version with a shield is also existing. Its name is Lora1276-C1 from niceRF. These different transceivers are using Semtech SX1276 chip. It makes this kind of chip interesting for regional low cost LoRaWAN design in association with a MCU. Here we are going to use it with an Arduino platform.
After having tested different LoRaWan gateway like Kerlink iFemToCell, TheThingsGateway and Kerlink Wirnet, in the past two years, I was looking for a new low cost indoor gateway for deploying TheThingsNetwork (the global crowd-sourced LoRaWan network) in my city.
Gateway are not all easy to shop, Kerlink at first. As one of my iFemToCell has burned into the hell this summer with no reason after only 3 months powered-on I was not looking for the same. TheThingsGateway has different semiconductor provider reseller but myne suffer of certain instabilities actually and I need to reboot on regular basis. So that’s the reason of this new try.
After making some post on Arduino MKRFOX1200, here I come with the first steps to use MKRWAN1300 board to send your first frame on TTN and also how to use them for discovering the TTN coverage around.
MKRWAN1300 board is a LoRaWan Arduino board based on the Murata CMWX1ZZABZ module. This module is capable for LoRaWan in Europe (868Mhz), NA (915MHz) Asia (923MHz) …. It is also capable for Sigfox in both zone (but actually not with this board as much as I know). Producing 14dB emission and capable for 20dB emission for FCC zone. The price of the Arduino board is about 40€ and it is largely available on Internet.
In this post we are going to see how to make the first steps with this board and create a device to map the TTN network coverage with and without a GPS.
The Adeunis Field Tester is a simple way to make test on a LoRaWan network. The device provide GPS information, temperature and an accelerometer to activate communications.
The device is big but it have a screen and you can have a direct feedback of the transmissions on the screen. It make it good for testing coverage manually. You can also program it to send messages periodically and easily put it in a car to create coverage maps thanks to the embedded GPS.
The following post explains how to set it to use it with TheThingsNetwork (as for any other network by-the-way).
