Thank you for your help to get started with the nRF8001!! It is working now.

The echo command is only valid in test mode. Take a look here to see the commands mode dependencies.

I checket the ps and it seems that I receive the right data:

0x01 (Debug)
0x03 (Lenght

0x84 (Command Response Event)

0x02 (Echo response)

0x83 (Status)

Status says that the state is invalide for the command.

After changing byte[0] (lenght) to 0x80 (=1000.0000) --> LSB is sent first --> 0000.0001 => lenght is 1 (if this is right?) I receive an reply from the nRF8001.

I send an echo command (0x02) (byte[1] = 0x40) and receive 0x21 -->LSB first => 0x84 which is the CommandResponseEvent.

It seems that there is a problem with MSB/LSB first because I have to swap the transmittig and receiving data?

Is this the right sequence: sending 0x02 and rreceiving 0x84 ?

When would i receive the EchoEvent 0x82?

Thank you!

Seems right. Note that when you receive data from the nRF8001 there is a debug byte that you can disregard, but this is documented in the ps. Please also see our porting guide here.
