• 🚴 Bike computers and sensors (speeds, thrust, power)
• ⚖️ Smart scales and pulsemeters
• 🏠 Smart home sensors (some Xiaomi Aqara models)
• 🎧 Wireless headphones and headsets (rare but encountered)

Unlike Bluetooth, the protocol is ANT+ Optimized to work with more devices at once, has less power consumption, and is better suited for transferring small data packets (such as heart rate or speed). On Xiaomi smartphones, this service is built-in by default, because many of the gadgets of the Mi Ecosystem ecosystem support the service. ANT+.

But there's a nuance: ANT HAL Service is just the middleman between the hardware of the smartphone and the applications, and by itself it doesn't know how to interact with the devices:
