It turns out, the SIM5320a has a Lua virtual machine onboard which can execute your own applications directly on the chip! I’m working to see if I can simplify my hardware design on my project by eliminating a controller board (currently a Pi). Also, I noticed the SIM5320a has two I2C pins on it which may be available via the Lua libraries, but more of that in a later post. Currently, I’d like to show how I was able to upload HelloWorld.lua to the Fona and execute it. For reference, my SIM5320a breakout board is connected to a Pi Zero, which I am accessing via my Mac and ssh. (I should post that set up, too, which was a bear, a lot harder than for a Pi2 or Pi3…)
