Sorting through my toolbox I came across an HC-06 Bluetooth Serial Module and realized I could use it to get wireless access to the Core’s Serial1 UART. These modules can be had for about $10 on Amazon.
Hookup is simple, really. There’s four pins on the module: TX, RX, GND and VCC. Hook your VCC up to 3V3, RX to the Core’s TX and TX to the Core’s RX. (I left out GND, but if you don’t know where that goes what are you even doing here?!)
At startup the red LED on the module will be blinking, you can simply pair it with any Bluetooth 2.1 computer/device that supports SPP (Serial Port Profile) with the very creative PIN: 1234.
After that, it should show up just like any other serial port! Once you connect to it in your terminal program of choice (Win: PuTTY; Mac: Parley) the LED will turn solid and it should function like any other serial port!
So, if you need to access more data than a LCD can provide and want to use your Core wirelessly (like it was designed to be used) even while debugging, I think this is a great way to go!
Here’s the module, in the back left corner of the breadboard:
