I am the software developer for a popular ham radio program called Waterfall Bandmap.

I recently installed the current RSP1 ExtIO and API on Windows 7. I am seeing a problem if I initially select the RSP1 ExtIO (but don't call StartHW), then select a different (non-RSP) ExtIO, then reselect the RSP1 ExtIO. Reselecting the RSP1 ExtIO gives the "Failed to find any RSP1's" message. The sequence of ExtIO calls I am making is:

1st selection of RSP1 ExtIO:
InitHW
OpenHW

Select other ExtIO (or sound card):
CloseHW

Reselect RSP1 ExtIO:
InitHW

This causes the "Failed to find..." message.

If I close my Waterfall Bandmap application, and restart it, I can, again, initially select the RSP1 ExtIO.

Is the CloseHW call failing to fully close the RSP1, or is there another ExtIO call I should be making ?

Thanks !
Steve

It looks like CloseHW isn't releasing the device (which is required before reacquiring it again). If you contact software@sdrplay.com I can work with you on that to resolve the issue.
