How can I disconnect ble from within a class

21 次查看(过去 30 天)
I'm attempting to use BLE from within App Designer. I am able to connect to my device with the following code.
properties (Access = public)
BLEDev ble % Handle to ble device
uart_w matlabshared.blelib.Characteristic % Handle to uart write characteristic
end
methods (Access = public)
function results = connect_BLE(app)
%%start talking to the device - reuse connection if it already exists
try
clear app.uart_w;
clear app.BLEDev;
catch
end
app.BLEDev = ble("Driver");
app.uart_w = characteristic(app.BLEDev, "6E400001-B5A3-F393-E0A9-E50E24DCCA9E", "6E400002-B5A3-F393-E0A9-E50E24DCCA9E");
results = app.BLEDev.Connected;
end
end
However I have not been able to figure out how to disconnect my device - the only thing that works is to close the app.
I matlab scripts, the way to close the device would be as follows, but this does not work in the class. Can anyone offer suggestions?
clear BLEDev

No, have not found any solution. I have not yet tried Matlab 2020, perhaps there are improvements included in that.

Hi Again,
I've solved the problem in a different way. I've declare the "BLEDev" variable as a Global varaible inside the class. Then simply calling "clear global BLEDev" allowed me to disconnect from the BLE device. Hope this helps.
Regards,
Imon

You can also set the objet to ""
app.bleOBJ = "";
clear app.bleOBJ
