Hello, I'm configuring nRF over SPI
After sending ANT_OpenChannel() 0x(A5,01,4B,00,EF), nRF response back with 0x(A4,03,40,00,4B,15,B9). The channel is opened & everything looks OK.

Do I always get response to control message?
Why is MSG Code15 generated?
The Document D00000652 Rev 3.1 doesn't give any explanation (there is no Code15)?
I assume that everything works fine? Am I right?

Thank you for your assistance.

The first thing I should point out is that the message codes are actually listed in decimal - so when you are receiving 0x15, you are getting message 21 - CHANNEL_IN_WRONG_STATE.

Sorry for the confusion - we will add a note to our documentation explicitly stating that these values are in decimal.

You will get a response from every command that is listed as having a reply in the ANT Message Summary, section 9.3 in the ANT Message Protocol and Usage document. For commands that have a reply, you should wait until you get the response before sending a further command. This ensures each configuration command has been correctly performed and helps prevent ANT from getting into an incorrect state.

when you receive the CHANNEL_IN_WRONG_STATE response, it is necessary to check the state that your channel is in. It is possible that the channel is already assigned. You should check the state that your channel is in by requesting the channel status (message ID 0x52). It is possible that your reset function is not working as expected.
