Question
What networking capabilities are available in wearable devices?
Short Answer
You can see framework image and table description below:
| Scheme | Dependency/Restriction | Methods |
|---|---|---|
| Wifi/esim | For esim, you need to determine whether it's supported for local area | Use http/https |
| BTProxy | 1) Phone with network2) Huawei Health app on phone3) Maximum downstream bandwidth is about 120 KB/s | 1) import btproxy package2) Use http/https |
| Wearengine | 1) Phone with network2) Huawei Health app on phone3) Corresponding App A' on phone | 1) App A' use http/https connect to server2) App A' use wearengine to send data to App A on watch |
Applicable Scenarios
Wi-Fi / eSIM
- When the wearable device has independent internet access (e.g., supports eSIM).
- No need for a paired phone; the device can connect to servers directly.
- Example: Uploading GPS tracking data during a workout, fetching updates directly from the server.
BTProxy
- When the wearable device does not have direct internet access but is connected via Bluetooth to a phone.
- The phone has the Huawei Health app installed and is connected to the internet.
- Example: Transmitting step count, heart rate, or other sensor data from the wearable to the cloud via the phone.
WearEngine
- When both the watch and the phone have corresponding apps installed (e.g., App A on the watch and App A’ on the phone).
- Data is first sent from the phone app to the server, and then synced with the watch.
- Example: Syncing health history, sending push notifications, or controlling media playback between devices.
