There are three main Apps provided by MbientLab to connect, troubleshoot, and gather sensor data on the MetaSensors.
The MetaWear App is great for troubleshooting your board and learning the ropes as a first time developer. It offers a way to send simple commands to the boar and get an idea of all that the MetaSensor has to offer. With the MetaWear App you can turn on LEDs, sample accelerometer data, get the temperature, and much more.
The MetaBase App is great for logging sensor data and downloading it at a later time.
The MetaHub App is great for streaming sensor data and retrieving it in real time.
