You can get the MAC address by scanning for the other dongle while it's advertising. To learn 
more about how to scan check out our 

scanning tutorial

. 

Open up the command prompt, on both computers, in the directory where the script is located. 
Start the script by typing 

1.

 

python sps_example

.

py  

 

and press Enter. 

You should now be prompted to enter 1 or 2 depending on what role the dongle should have. 
Set one as Peripheral and the other as Central. It is advisable to setup the Peripheral first as the 
Central will need someone to connect to. 

You should now see in the terminal how the dongles send and recieve data to and from each 
other. 

The script will run until you stop it. 

And that is an example of how we can send data between two dongles. If you want to stop the 
script, you can simply press control C.
