ADAFRUIT WEEKLY EDITORIAL ROUND-UP
We’ve got so much happening here at Adafruit that it’s not always easy to keep up! Don’t fret, we’ve got you covered. Each week we’ll be posting a handy round-up of what we’ve been up to, ranging from learn guides to blog articles, videos, and more.
BLOG
the return of the zombie bluefruit ez-link!
many many years ago we developed and sold a pair of products called ez-key (https://www.adafruit.com/product/1535) and ez-link (https://www.adafruit.com/product/1588) that implemented bluetooth classic HID and SPP respectively. they were popular because we actually did the two ‘right’ – with SPP having control lines for remote programming of boards that would normally use the RTS/DTR/CTS lines for auto-reset control.
to do the initial development we had to source CSR chipset BT modules, get them FCC certified and then develop for them using the very-unpleasant-and-totally-nda’d CSR firmware package and IDE. and then our module supplier closed shop and everything got extremely annoying to replace and recertify and we ended up discontinuing the line.

LEARN
IoT Food Scale with Azure and CircuitPython
In the NAU7802 Food Scale Learn Guide, you can build a food scale using CircuitPython, a NAU7802 STEMMA board and a strain gauge. In this guide, you’ll take that project and connect it to Microsoft Azure to log the weight measurements over time. Additionally, you’ll setup a text alert when it looks like you need to refill the food container.
