The previous post about the LoRa board I bought via Aliexpress, I did in Dutch. I should have know that, like often happens with the more technical posts on my blog, the majority of people interested in it are not from the Netherlands. So, this follow-up post about connecting a sensor to it, I’ll do in English again. I will do […]
Zoekresultaten voor: lopy
Tot voor kort had ik 2 verschillende LoraWAN nodes in huis: een tweetal LoPy‘s, waarvan er eentje dienst doet als single channel gateway en een Marvin. Beide zijn niet bijzonder goedkoop, een LoPy met ontwikkelbordje en antenne kost zo’n 50 euro excl. verzendkosten. Een Marvin kost bijna 85 euro excl. verzendkosten. Niet echt sensoren dus die je ergens “kwijt” wilt raken. Terwijl een […]
Now that Alex explained everyone how to use MQTT in combination with the LoPy, I thought it was time to show some more advanced uses of MQTT in case you still had no idea why you would bother learning to understand it. The nice thing about MQTT (MQ Telemetry Transport or Message Queue Telemetry Transport) as a protocol, is that it […]
Als het in het onderwijs in Nederland over “programmeren” gaat worden eenvoudige vragen al heel snel ingewikkeld. Dus een vraag als “Welke programmeertalen zouden onze leerlingen/studenten moeten kennen?” (bron) is niet helemaal zonder risico. Immers, je moet dan gaan nadenken over het doel dat je daarmee hebt. Wil je ze leren programmeren? Of juist coderen? Of software ontwikkelen? Ik ga niet […]
What happens if you take a LoRaWAN node with you in a train while you travel across the Netherlands for about 2,5 hours? I did not know and wanted to find out today because I had to be in Zwolle for a meeting. So I charged a big external battery (with 2 USB ports), drilled a couple of holes in a […]
At the moment, the console page of The Things Network has some problems getting the Gateway page. It has been reported on the forums, it appears to be a front-end thing, the gateways themselves appear to be working just fine. So unless you want to get info about your gateway, add a new one, remove or change one, there should be […]
If there is a thing that is dislike most, than it is giving up on a technical problem before it is solved. So, although this weekend a late cold finally managed to make me sleep more than usual, I did manage to spend some time with The Things Network, the LoPy Nano Gateway and the Marvin Node. So, one thing that […]
If your are used to learning stuff without there being a clear manual available, without a teacher that gives you a step by step breakdown of what to do, like when you like to experiment and play with electronics or ict, then you know how frustrating the process of trial and error can be to get something to work. And how […]
My apologies to my regular Dutch readers, given the nature of the topic I am going to do this post in English also. I promise to return to the regular Dutch posts. When I wrote about connecting the Marvin board to the LoRaWAN network in the previous post, my conclusion was: wow, great, KPN truly does offer easy access to LoRaWAN […]
I will do this post in English because the number of potential readers will increase, and because I do have some additional questions that are more likely to be answered this way. So, last weekend I played around with my Pycom LoPy boards. A while back they announced that it would finally be possible to setup a LoRaWAN Nano Gateway with […]
