In the previous post I wireless installed a clean version of Raspbian on a Raspbian Pi 3.
Now it’s time to do something usefull with this clean install, like add iPhone presence detection to a Raspberry Pi 3.
In this post I will layout the steps needed to do this
Retrieve MAC adress (bluetooth)
Put your iPhone bluetooth into discovery mode (Settings -> Bluetooth)
Make sure your raspberry pi is rebooted after the last update / upgrade
Otherwise you may experience an error message saying:
Device is not available: No such device
Now run following command:
hcitool scan
It should find your iPhone and show you the mac addres
Ping device
You can now “l2ping” that mac address to see if it is available:
sudo l2ping -c1 -s32 -t1 'XX:XX:XX:XX:XX:XX'
To make the output more readable you can extend the command into something like:
sudo l2ping -c1 -s32 -t1 'XX:XX:XX:XX:XX:XX' > /dev/null && echo 'On' || echo 'Off'
