What's the expected reply to a command packet? If I send 0,0,0,0 what should I get back from the copter?

I'm seeing an ACK status byte of 0x00 which looks like a good ACK. The payload has nothing though. Normal?

Hi,

For the commander packet there's no reply, so the ack will be empty. There's always an ack sent back from the Crazyflie when you send data to it, this is how the Crazyflie transfers data back to the host.
