Deep Dive w/Scott: BLE Workflow

Join Scott today as he answers questions and continues working on the BLE workflow code in CircuitPython. Scott is sponsored by Adafruit to work on CircuitPython. Support them, and by extension me, by purchasing hardware from https://adafruit.com Chat with him and lot of others on the Adafruit Discord at https://adafru.it/discord. Deep Dive happens every week. Normally Fridays at 2pm Pacific but occasionally shifted to Thursday at 2pm. Typically goes for two hours or more. Questions are welcome. Edit: NEXT WEEK IS ON THURSDAY!
