Notes for setting up the Bluetooth strain gauge (RN42-0452) with e.g. MATLAB:
In terminal (you may have to manually switch on your bluetooth connection)
- Scan for devices:
hcitool scan
Look for the MAC-ADDRESS and copy it into the following <MAC> This will bind the device to the name /dev/rfcomm1:
(sudo) rfcomm bind /dev/rfcomm1 <MAC>
Afterwards, check if it has been bound:
rfcomm -a
To remove the binding:
rfcomm release /dev/rfcomm1
It now appears as a serial connection, and you can use fopen() and fscanf() to read in data to MATLAB: example:
instrreset;
s = serial('/dev/rfcomm1', 'BaudRate', 115200);
fopen(s);
data = fscanf(s); %read data into array
disp(data);
fclose(s);
