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....

[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)....

Following up with the series of affordable RF tools I started with the RF Power Monitor 8000, maybe the N1201SA by Accuracy Agilty (sic?) Instrument (AAI) is one of the most exciting devices around. The device is sold as “RF Vector Impedanze Analyzer” and, although it's not a full VNA (Vector Network Analyzer), it gives you enough information to profile your antennas and, according to some reviews, it's so accurate it can compete with professional equipment....

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....
