Hello, I try to use Matlab Mobile (Android device) to read temperature value from optris CS LT 15 Sensor. I can connect that sensor with other application named 'Serial USB Terminal' and that is working correct after choice CP210x driver. In matlab I try to use that trough:
s = serialport('/dev/ttyS0/',9600)
On PC it is working properly but In android device I occure an error like below:

Instrfind command doesn't found any open port and I am sure that right.
I don't know what is the reason of that? Permission, driver? That is not require for other app. I dont have any idea now. Please let me same help.
Below addidtional photo, maybe will be usefull.

I am having the same problem with the ipad. I am trying to use matlab mobile to acquire data from an Arduino pressure sensor, and receive the same error message.

Hi Maciej Solarczyk,
It seems like you're trying to use MATLAB Mobile on an Android device to read temperature values from a Sensor using a serial connection. MATLAB Mobile allows you to connect to a MATLAB session running in the MathWorks Cloud. The Serial Port interface is supported by the following platforms, https://www.mathworks.com/help/matlab/import_export/troubleshooting-serial-port-interface.html#:~:text=The%20serial%20port%20interface%20is%20supported%20on%20these%20platforms. Unfortunately, it was not supported in MathWorks Cloud. So, Serial Port interface cannot be used from the MATLAB mobile.
One way to process the data from the sensor (offline data), since you are able to connect to the sensor using 'Serial USB Terminal'.
- Gather the data from sensor and save the data locally.
- Upload the data to MATLAB Drive. Now the data will be accessible from multiple platforms.
- Perform the operations on the data from one of the supported platforms.
Refer the following resources for more information,

Hi, I posted this answer thinking it would help others. As per the documentation, Serial Interface is not supported in MATLAB Cloud or MATLAB online. I know that we can connect Raspberry Pi in MATLAB online. I'm wondering how you connected Arduino using the Serial Port Interface.
