Using an ESP32 and BLE to Avoid Losing Your GoPro #celebratephotography
Creative problem solving by Konrad Iturbe on Hackster.io:
Tether? Check. Sticker with my number? Check. An IF_FOUND.txt in the SD card? Check. A device that beeps whenever the camera is out of range or the battery died? Huh?
I had this idea for my upcoming ski trip to get notified in case I lose my GoPro. Problem is turning on WiFi will drain the battery very quickly so I resorted to using Bluetooth, the camera spawns a Bluetooth connection when pairing, and that’s not ideal for me since I need to get a BLE signal as soon as the camera boots up.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
