What are the command response codes for the network API?

Steve Conklin

Commands issued to the radio using the TCP/IP API return a hex value representing a 32 bit value.

This is documented on the wiki as follows:

"<hex response> = ASCII hexadecimal number (32-bit) return value (see table below for possibilities)"

but there is no table.

From another post in this forum, I found the following:

"A 0x1xxxxxxx message is styled as Informational.  A 0x5xxxxxxx is an error."

And from observation, zero is success.

Is there any more information available than this?

Thanks.

Yes, the original intent was to post all of these in the wiki along with the command they could be issued for.  The wiki has aged a lot though and so there's not a lot of info in there that we'd like to get added.  Here's a definitive list as of today - not with a lot of descriptions.  The ones that have an SL_R also have a text description further down in the list
