2017年9月30日打开Matlab，在add on中下载Android Sensor Support from MATLAB . MATLAB 与传感器间的通信连接通过一个mobiledev对象实现代码如下：

m = mobiledev creates an object m that reads sensor data from any device running MATLAB ® Mobile™ with the same MathWorks ® account. The object can read data from five types of sensors: acceleration, angular velocity, orientation, magnetic field, and position.

On your computer, create a mobiledev object, m, in MATLAB. For more information about these steps, see Install MATLAB Mobile on Your Android Device and Sign In to the Cloud. Start MATLAB Mobile on your Android device. On the Commands screen of MATLAB Mobile , create a mobiledev object m . Start MATLAB Mobile on your iOS device.

So enter m = mobiledev and see what the result is. Then we launch the sensors.m script on command line of the MATLAB Mobile on the phone. Leave it running, do not lock the phone or minimize the app. Then we start the second script (plotsensors.m) on our PC, which has the same MATLAB Drive account enabled, change current folder to MATLAB Drive (where sensors.mat data file will be created) and On the Commands screen of MATLAB Mobile, use the mobiledev command to create an object that represents your mobile device. To connect to sensors on the device and collect data, you create a mobiledev object in MATLAB. You can also acquire sensor data locally on the Android device, with or without a network connection.

m = mobiledev 创建对象 m，该对象从运行 MATLAB ® Mobile™ 的 Android™ 设备读取传感器数据，该设备与运行 MATLAB 的计算机连接到同一网络。该对象可以从五种传感器读取数据：加速度、角速度、方向、磁场和位置。 Stream Sensor Data with mobiledev.logging Property. Stream data to MATLAB ® running on the MathWorks ® Cloud with a WiFi or cellular connection.

Start MATLAB Mobile on your iOS device. On the Sensors screen, tap the sensors that you want to send data from. Place the device where you want to get the sensor data. On your computer, create a mobiledev object, m, in MATLAB.

On the Commands screen of MATLAB Mobile , create a mobiledev object m . Start MATLAB Mobile on your iOS device. Sign in to the Cloud, if prompted. On the Sensors screen, tap the Orientation sensor.

m = mobiledev creates an object m that reads sensor data from an Android™ device running MATLAB ® Mobile™ that is connected to the same network as a computer running MATLAB. The object can read data from five types of sensors: acceleration, angular velocity, orientation, magnetic field, and position.

Let’s explore this workflow through an example that illustrates the collection of acceleration data and using it to count the number of steps taken. Step 1: Turn on the Accelerometer Start MATLAB Mobile on your iOS device.

The capabilities of the "mobiledev" function have changed quite a bit over time. It used to be for MATLAB Desktop, you would use it on desktop MATLAB and it would connect to a mobile, which would get data to your desktop from that mobile running MATLAB mobile. This MATLAB function creates a mobiledev object m that reads sensor data from any device running MATLAB Mobile with the same MathWorks account.

Stream Sensor Data with Sensor Controls. Send sensor data to MATLAB ® running on MathWorks ® Cloud using MATLAB Mobile™ sensor controls. To communicate with the iOS device and acquire data from the sensors, you will create the mobiledev object as part of this procedure. You cannot log the sensor data until you create the object.

Place the device where you want to get the sensor data. On your computer, create a mobiledev object, m, in MATLAB. m = mobiledev creates an object m that reads sensor data from an Android™ device running MATLAB ® Mobile™ that is connected to the same network as a computer running MATLAB.
