unable to stream sensor data from mobile device to computer

I follow the matlab version r2018a and try to stream sensor data to my computer.

Since matlab has changed policy and stream sensor data into cloud. So I follow the latest instruction in matlab web.

I enter below in my comupter

>> connector on

>> m=mobiledev

But in my ipad , although I enbale the sensor

the start button cat't be hit, always show gray and computer can't get data.

>> connector on

The first time you run the MATLAB Connector, you must specify a password.

Enter the same password when you set up MATLAB Mobile on your device.

Password: Aa1234aaa

DNS name: xxxxxxxxxxxxxxxxx (I hidden it)

IP address: 192.168.0.103

Use this link to test the MATLAB Connector:

http:// xxxxxxxxxxxxxxxxx (I hidden it)

If the test is successful, but MATLAB Mobile cannot connect,

your computer might have multiple IP addresses. To determine

the correct one, see Determining the DNS Name or IP Address of a Computer.

>> m=mobiledev

m =

mobiledev with properties:

Connected: 0

Logging: 0

InitialTimestamp: ''

AccelerationSensorEnabled: 0

AngularVelocitySensorEnabled: 0

MagneticSensorEnabled: 0

OrientationSensorEnabled: 0

PositionSensorEnabled: 0
