Microchip RN2483 Lora
Making downlink working correctly with RN2483 on LoRaWan is not a simple a quick thing to do if you do not have all the keys to do it. After spending some time to fix my code for this, here are the tips to consider and not forget !
LoRa GPS Tracker
Todays work was to make a simple GPS tracker communicating over LoRaWAN to check the coverage of my LoRaWan gateway in the city. Basically this tracker reports a position per minute to the network. If coverage is good, position will be recorded in the backend. That’s all !
This post details how to do it easily with the low cost and common components : Arduino for the master, Microchip RN2483 for LoRaWan communication and L80 for GPS positioning.
Microchip RN2483 Lora
The microchip device is in most of the case delivered with a 0.9.5 a version 1 seems to be available even if not downloadable from microchip product webpage.
This link contains a version 1.0 and a java tool that helps to configure the chip with a graphical interface. It is really usefull.
Main problem I found with the tool: it is not possible on a MAC to open the firmware file to load. Other functions are accessible. On W7 it is possible to flash the device :
Actually on May 1st 2016 the current firmware version is 1.0.1 you can get it following this link. This version is the one validated for network operators like Objenious.
