Development Environment
Mediatek has provided LinkIt ONE Software Development Kit (SDK) for developing apps for LinkIt ONE devices. It consist of a SDK that integrates with the Arduino software to deliver a familiar development environment. With this SDK the existing Arduino apps can be easily ported. The SDK compiles Arduino Sketches into LinkIt ONE execution file format (.vxp). It includes LinkIt ONE API libraries supporting the core Arduino functions and LinkIt ONE communication features like-
- 2G mobile network (GSM and GPRS).
-GNSS (GPS, GLONASS and BeiDou)
-Bluetooth (2.1 and 4.0).
-Wi-Fi.
Hardware
The Linkit One development board comes with dual Wi-Fi and Bluetooth, GSM (2G) and GPS/GLONASS antennas as well as a 3.7V Li-battery. It is easy to get started with Grove shield and sensors as they are compatible with this board.
There are 3 slide switches on LinkIt ONE which are used to configure the function/working mode, which makes the board little complex for the beginner and hence it is highly suggested to read the user manual once before getting started.
This board offers a range of awesome features which makes ideal for IoT applications and it comes with an affordable price too, we will keep leveraging this power packed board from the complete beginning from installation and configuration to making some high end applications with cloud.
