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 […]

I still wasn’t out of “what if…” scenario’s for the devices I had been playing with in relation to The Things Network / LoRaWAN. Because, although I had used the WiFi (and of course LoRA) capabilities of the LoPy a lot, I had not yet played with its BLE (Bluetooth Low Energy) capabilities. For that I needed something else that could […]

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 […]
One of the challenges left with regards to the LoPy was to find a way to actually connect sensors to the node. I had little luck with the DHT11 temperature/moisture sensor (one of the drawbacks of MicroPython over regular Arduino code is the lack of libraries) and didn’t have any I2C sensors lying around. But I did of course still had […]

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 […]
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 […]
