This week became “Tinker Every Week” more than “Make Every Week,” as I tried to make a new device-sniffing device.
Previously, I managed to detect wifi signals around me, and I wanted to do the same for Bluetooth devices, including gadgets using new “Bluetooth Low Energy,” or BLE, signals. These include iBeacons and other tracking systems being deployed more and more around us.
I got myself a Bluefruit LE Sniffer from Adafruit ...
... and rigged it up to my Raspberry Pi.
