Slogging slowly forward with Meshtastic. 
I've attached LoRa and Bluetooth antennas (critically important to avoid frying the device!2), flashed stable firmware, and so far, watched the blinking lights...😜🤣
The RAK is connected to my MacBook via USB/serial, and to a Meshtastic app on my Graphene phone via Bluetooth.
Discovered I need to upgrade Mac OS to run a Meshtastic app...😳 Well, I've procrastinated on that far too long, so now I'm motivated...😆
ATM, I have no nodes to talk to; another, different LoRa device arrives tomorrow. More steep learning curve, no doubt. 🤔🧐
Stay tuned, more news as it breaks...
