In typical Wavecom fashion, No - there isn’t. 😠

Sierra Wireless have yet to address this…

What return code(s) are you getting from your WIP API calls?

WIP Events?

You can gain extra information by enabling ATI level 1 traces: this will show you the AT Commands being used internally by WPI - and, more importantly, the responses…
