QuestionHow to retrieve "terminal" output? Pin
Vaclav_17-May-19 7:26
memberVaclav_17-May-19 7:26 
I have pretty much given up on using bluez hci functions.
Instead I am looking at bluetoothctl and hcitools.
At this point I can visually identify both local and "nearby" bluetooth devices using "system" calls in my C++ code.
I am not sure how to use these scripts for actual transfer of data.

For now I like to retrieve the received text for further processing - using redirection . See bellow example when using terminal. My C++ code provides similar output to console.

I understand that some command require "sudo" (user) but do not understand why the redirection is failing.
Perhaps I need to provide detailed path to the "test" file ?

Appreciate any help.
