Just get to the point.
I have a Bluetooth dongle connected to my PC. I can read a MAC address and internal clock value by typing `hcitool dev` and `hcitool clock` in command line. You can see demo in link below:
What I want is to make GNU Radio get those values/contents.
Currently, I've planned to make a source block expressed in pseudocode:
work(args) {
file_pointer = popen("hcitool dev"); // or "hcitool clock"
buf = read(fp);
val = some_char_array_manipulation(buf);
publish_message(val);
pclose(file_pointer);
}
Recently, I found that ControlPort can bridge GNU Radio and other programs. Well, however, I am new to ControlPort (just used for PerfMonitor) and seems more complicated than the pseudocode above.
Which would you recommend? One condition is, I need to retrieve contents from "hcitool clock" as fast as the system (GNU Radio) can.

Jeon.
