EV3 Bluetooth

The EV3 uses a Panasonic PAN1325(A) bluetooth module with a Texas Instruments chip. It is Bluetooth 2.1 + EDR.

Early models have Panasonic part number ENW8918A2JF with TI part number CC2560.

Staring around July 2015, EV3s started shipping Panasonic part number ENW8929A2KF with TI part number CC2560A instead.

Notes

• Starting around July 2015, LEGO started shipping EV3s with a different Bluetooth chip. (Running hciconfig -a indicates that the newer chips are BT 4.0, but they don’t actually support BTLE).
• We use the same Bluetooth firmware files that are included in the official LEGO EV3 firmware. They are packaged in firmware-ev3.
• Communicates with the CPU via UART2
• Requires a 32.767MHz “slow clock”. This is generated by ECAP2 (in APWM mode).
