18-
* Starting in July 2015, LEGO started shipping EV3s with a different Bluetooth
19-
chip. (Possibly Bluetooth 4.0?)
20-
* We use the same Bluetooth firmware as the offical LEGO EV3 firmware. It is
21-
packaged in [firmware-ev3](https://github.com/ev3dev/firmware-ev3).

* Starting around July 2015, LEGO started shipping EV3s with a different Bluetooth
24+
chip. (Running `hciconfig -a` indicates that the newer chips are BT 4.0, but
25+
they don't actually support BTLE).
26+
* We use the same Bluetooth firmware files that are included in the official LEGO EV3 firmware.
27+
They are packaged in [firmware-ev3](https://github.com/ev3dev/firmware-ev3).
