ANT Forum

I'm wondering about the details of the command pipe time message.

13.2.5 Time (0x03)

The time message is used by the host application to send the current time to the client application. It may also be requested by the host application, in which case, the time message will be sent back to the host application as a response.

I'm wondering about the second use case here. Is that done with a Request (0x01) command pipe message and response as Time (0x03) or is this supposed to work some other way?      

You are correct, you request using the Request command and the Client should send back the Time command as a response.      

However,

this command isn't mandatory - to my best knowledge.
And I've seen devices that don't support having their time set via ANTFS command.

Cheeers,

Sorry for digging up this old post again, but I'm still a bit unclear on what to expect back here. From a Vivofit 2 I'm getting:


(base 10, each is one byte)

This is from a Time (0x03) request. The response is not documented in the ANT-FS standard as clear as it is for Create File (0x04). Can someone shed some light on this?
