BLE Bluetooth Low Energy
Connect IoT devices with low-power wireless communication
BLE (Bluetooth Low Energy) enables wireless IoT devices with months of battery life. Mid-level embedded engineers earn $110-145k; senior architects design IoT ecosystems at $190-260k.

BLE (Bluetooth Low Energy) is a wireless communication protocol designed for IoT devices, wearables, and sensors. It consumes 10-100x less power than classic Bluetooth, enabling devices to run on coin-cell batteries for months or years. BLE uses GATT (Generic Attribute Profile) to organize data into services and characteristics. Devices operate as central (initiator) or peripheral (advertiser) in star topology networks. - Ultra-low power: Coin-cell powered devices run for years, not weeks
