|
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). |
| 23 | +* 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). |

23 | 29 | * Requires a 32.767MHz "slow clock". This is generated by ECAP2 (in APWM mode). |
