There are many Bluetooth modules with different purposes, and I didn't look into which function my first pick provided. I guessed wrong and discovered that they were suited to acting as low-energy beacons, not wireless serial ports.
Wrong kind of modules
My second choice started with internet research, which should do the trick. The datasheet walked me through the connection procedure, and I executed it manually with a couple of serial to USB converters.
Following the steps
The steps I followed manually needed codification, so I wrote up a sequence in pseudo-code and verified they would work reliably. I felt like the last time I used Bluetooth like this.
This should link up my modules
One of the differences between these new modules and the old ones was that the initiating unit needed a pin connected to Vcc, so I installed a pair of header pins and a removable jumper.
Hardware change for this module
With my pseudo-code as a guide, I wrote up the functions to pair with a waiting module. The hardest part was recognizing incoming data. My solution was undoubtedly kludgey.
Two Bluetooth modules connected wirelessly
There was good news when I discovered that my Bluetooth modules would automatically pair up when powered. All my coding was in vain since I could have stopped after going through the steps manually, but this automatic linkage makes their future use more appealing.
Linked up neatly
