Wireless access to OLA terminal

Thanks for the update Paul. We’ve been successfully using external BT modules. First the SparkFun BlueSMIRF, then when that was discontinued, the Adafruit Bluefruit LE UART Friend https://www.adafruit.com/product/2479.

To save power we use the Qwiic bus to power the BT modules. It’s not ideal, but it works. We’re streaming data and doing file downloads via Bluetooth to a nearby RPi.
