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...

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...

The industry has been talking about edge computing for some time now. The idea is to distribute the data storage and intelligence in locations closer to where they are needed and only use external services when absolutely necessary. Centralized cloud...

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...

Unit testing your code is peace of mind. It has two main direct benefits that impact on your confidence about the code you are writing: Testing expected behaviors Avoiding regressions (i.e. breaking something that was working fine before) Unit testing...

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...

The Arduino Core for ESP8266 and ESP32 uses one SPI flash memory sector to emulate an EEPROM. When you initialize the EEPROM object (calling begin) it reads the contents of the sector into a memory buffer. Reading a writing is...
