Arduino IDE Library to AS
Arduino's IDE is oddball in that the libraries are not pre-compiled as .o files or a .a (archive) of .o files. Instead, Arduino's IDE attempted to simplify C/C++ building by...

IoT networks
er, we have this wee little issue called curvature of the earth. Radio horizon is not very far away unless you have high-site  antennas. And 433MHz has severe regulatory...

Unwanted warning from compiler
I use parentheses  to make it clear what the order of precedence is by intent. I avoid using commas to separate expressions. Bad form. Dangerous.

First Wireless Communication for Beginners (433Mhz, Atmega8, AtmelStudio)
Funny thing about beginners and telemetry wireless... The users tend to start with $2 radios which are so crude they are not easy or fun to use. Like learning to drive in a stick...

IoT networks
Sigfox, what a hoot. Unlicensed ISM band, sub-GHz. It'd take an impractically huge number of self-funded mesh network node members to support semi-ubiquitous coverage.  ...

MicroSemi "LoRa" Chips?
LoRa radios use spread spectrum with long code lengths, lots of FEC, etc. This lets them demodulate at very low or negative SNRs (due to post correlation gain). These $5 radios...

Seeking low power wireless recommendation
Re above.. WiFi and Bluetooth are industrial alliances' trademarks. These are based on IEEE standards like 802.11, 802.15.4, etc. The IEEE standards define frequency bands in...
