Adventures in IoT EP2: Turn on BLE (Bluetooth Low Energy)
In this episode, Jorge covers some relevant Bluetooth Low Energy concepts and puts them in practice by using them in writing the firmware of a Raspberry Pi Pico board. In this firmware, we use the on-board LED, read from the on-board temperature sensor and implement a BLE peripheral that offered two services and a characteristic that depended on measured data and could push notifications. ✅ Sign-up for a free cluster at → https://mdb.link/free-vXFjpScH8AQ ✅ Get help on our Community Forums → https://mdb.link/community-vXFjpScH8AQ Adventures in IoT playlist → https://trymongodb.com/3R38iGX Subscribe to MongoDB YouTube → https://mdb.link/subscribe
