Hubble Device SDK

Add global connectivity to your device using its Bluetooth® chip.

What This Does

The SDK encodes your data into Bluetooth Low Energy (BLE) advertisements. Hubble's gateways pick them up and deliver your custom payload and device location data to your backend via API.

No cellular modem. No SIM card. No gateway hardware to deploy. Just add the SDK to your application firmware.

Supported Platforms

Works with any Bluetooth LE 5.0+ chip.
