The MikroTik wAP LoRa8 is here

Last week I was at the The Things Conference in Amsterdam with a collegue from TTN Catalunya. You could smell the hype. Most of the big players were there. I had the chance to attend some interesting presentations, talk at the booths with people from PyCom, RAK, WifX or SeeedStudio and meet and devirtualize some people like Gonzalo Casas or Andreas Spiess. Then there were the workshops. You know, I've done a lot of workshops myself and I know that it is hard (if not impossible) to go through a complete workshop without issues....

Hacking the TTI Indoor Gateway

[Update 2021-08-11] Added information on how to enable the CP2102N on the TTIG thanks to @_pub_feuerrot. Four years ago The Things Network (TTN) kind of revolutionized the IoT world with their effort to reduce hardware and software costs to implement a commons LoRaWAN network. Their bet was backed on Kickstarter by almost a thousand people with almost 300k€ to help create a low-cost LRaWan gateway (and a platform and end devices too)....

RF power monitoring tools on the cheap

Recently we at @ttncat had to prepare a crash course on LoRa, LoRaWAN and The Things Network for a professional school in Barcelona. It was a 15 hours course that covered from the very basics to some more advanced topics on RF like link budget, attenuation or impedance matching. It was fun to go back to my years at college and revisit and update some of those topics. And at the same time it was a great opportunity to upgrade my toolbox....

Monitor your TTN gateways with Node-RED

This time I'd like to write a quick post about a small project we've been working on at the The Things Network** community in Barcelona** (@ttncat). We were worried about the monitoring of the gateways we have deployed, both as a community but also as individuals. Some of our partners have also deployed their own gateways and they are part of the community. The TTNCat gateway at Vista Rica in Barcelona So how do we get (almost) real-time notifications of incidences in the local TTN network?...

WhiteCat ESP32 N1

I do not do reviews usually, but I sometimes do exceptions. In this case, it's worth doing it, due to 4 main reasons: It's a software & hardware open source project It's local (local to me, that's it) It's led by two good friends It's related to LoRa and The Things Network It's awesome! OK, they were actually 5 reasons, but the last one just slipped in. The WhiteCat ESP32 N1 Board The WhiteCat ESP32 N1 Board is a green board in a long-ish form factor, longer than the LoPy or the Chinese ESP32-based LoRa boards....

RAK833 meets Raspberry Pi

You might have heard about The Things Network (TTN from now on) here or somewhere else. If you have not, then it's a good opportunity to visit the project and check if there is a community of users around you. I have been a core member of the TTN Catalunya community for over 2 years now. This year we are working hard deploying several new gateways in Barcelona and doing workshops and hackathons with the main goal of helping individuals and social entities to carry out projects around a LoRaWan open, libre (free as in freedom) and neutral telemetry network....

M5Stack node for The Things Network

I have a couple of IKEA-like boxes in my home office labeled “Inbox”. They are full of stuff I buy and store waiting for some free time to spend on them. From time to time I pick one of the boxes and take a look at its contents. They are actually full of “wow” stuff. I would buy again most of the things there but at the same time I fear I'm just collecting stuff that will become junk....

Arduino MKR WAN 1300

I've been testing quite a few LoRaWan nodes lately for TheThingsNetwork.cat, some based on HopeRF RFM95W (over AVR, ESP8266, ESP32,…) others using Microchip's RN2483 (an old friend of mine). I have a RAK811 waiting in the INBOX but the last one I've been playing with has been the new Arduino MKRWAN 1300 (so new there is no product page yet) and I liked it, quite a lot. The device is one of the MKR series Arduino is pushing forward....

Low power in LoRaWan world - Meet the RN2483

I'm working on a project were I have to build a network of battery powered sensors over a territory the size of a small town.The sensors will monitor power consumption, temperature and humidity in energy poor households. Often the families in that situation can't afford an internet connection at home so WiFi is out of question. GPRS would be an option but lately other radio technologies have come to my interest....
