Adaptive data rate must be only used for static/fixed nodes. If you use a moving node you must disable ADR and use slowest DR (SF12). In this case more gateways will receive the data but higher power...

Hi @markstanley, this project looks really interesting. How is the status of it? There is a GPS grabbing technology called "Fastloc", that will grab the sky for 30ms? and return raw data that can be...

I think I forgot to link it. Here's the source code take at measuring coverage: https://github.com/ttn-zh/ttn-coverage-tracker We pull data from the REST API, parse it according to different formats...

Hey guys, I'm trying to send a message through TTN by using a Raspberry Pi 2 Model B with Cooking Hacks bridge and LoRaWAN shield from Libelium. All looks well and I can access the LoRa module through...

Are you within reach of an operating (full) gateway? Looking at gateway map it seems all gateways in The Hague are down...

Thx! Tried this using the duff Snooze Library for Teensy. In itself the library works fine (The Teensy uses 4.4 uA during hibernate which is quite OK I think). Need to fiddle a little with the timed...

I'm processing the data and pushing it to github in geojson format, so you can already integrate it, just pull those files into layers of your map. You can even do it client side with a request to the...

Even if you don't use the timed callback, you have to increase the hal_ticks by the the amount of time you hibernated (for the duty cycle, etc.). You could use the addticks variable to do that.

Two day's ago I received the board and I'm waiting for the correct antenna to arrive. My idea is to place the gateway in The Hague. This will be my first LoRa project so I hope I can give you some...

I'll try to give a brief, but clear description of my setup. The major difference between mine and that of gonzalocasas/pade.nl is that I don't require a GPS on the LoRa node. I use a smartphone that...

Thanks @sergiosena - I read a bit about Fastloc and noticed the company also sells something called nanoFix (http://www.pathtrack.co.uk/Site/nProducts.html) which is very lightweight. Out team is...

LMIC-1.51 fitting in Arduino Atmega 328
Hi, Looking for a simple and cheap way to make a node that would run the complete LoRaWAN stack, I have been porting the stack to the ESP8266 (see other topic). At the same time, I wanted to run that...

Nice board. Would have liked a Nordic or STM based Cortex M but this is way better than the silly AVR and PIC based stuff that is out there, so I backed the KS.
