LoRaWAN is getting more an more popular, both for terrestrial and increasingly with low-orbit satellite systems. The ‘Long Range’ in ‘LoRa’ makes it an ideal solution for low-power and low data rate applications. For a university research project we selected the Semtech SX1261/62 transceiver together with the NXP LPC55S16 mikrocontroller. Because the board used for that project is not available for the public (yet), I share here how you can run the LoRaWAN stack with the NXP LPC55S16-EVK.Continue reading

Tutorial: RAK813 LoRaWAN+BLE+GPS Sensor Node with Eclipse IDE
In the IoT world, it is all about security, connectivity and low power. LoRaWAN with the Things Network is able to connect devices over several kilometers, and I’m running my gateway for it already (see “Contributing an IoT LoRaWAN Raspberry Pi RAK831 Gateway to The Things Network“). This tutorial is about building a BLE+LoRaWAN+GPS sensor node with GNU tools and Eclipse:

LoRa and LoRaWAN is getting the de-facto wireless IoT network in my area. No surprise that traditional telecom providers like Swisscom trying to monetize the ‘Internet of Things’ area. Luckily there is an open and free alternative: https://www.thethingsnetwork.org/. Volunteers, enthusiasts and members in the different TTN communities build gateways and offer free LoRaWAN network access. I wanted to contribute to that grassroots movement with building my gateway, providing LoRaWAN access to my neighborhood.
Enclosure for the Remote Robot Controller with LCD Display
The first enclosure for the INTRO robot remote controller board (see “INTRO Robot Remote – First Production PCB“) is ready, and it is looking good:

After the first prototype (see “Prototype of Wireless Remote Controller with NXP Kinetis K20“), we have received the boards and populated a first PCB to verify everything is working properly.
Prototype of Wireless Remote Controller with NXP Kinetis K20
For next semester I plan to use the tinyK20 as a remote controller for the Zumo Robots. I already had an early prototype presented in “3D Printed Gameboy and Remote Controller with tinyK20 Board“, so here is the next iteration of, in a sneak preview:
