device in use

I am getting the following error - RTL-SDR Device #1 in use -
Can someone point me in the right direction.
This is a new install on Win11, worked perfectly on my old W10 machine

Would help if you stated where you're seeing the error (an app?) Has computer been restarted since first experiencing error?

It means the dongle is being seen as in use. Try unplugging it and reinserting it.

Good point. What software are you using for the SDR when you get that error, SDRSharp?

I suspect it may be the batch file I'm using ??

start FMP24 -i1 -o20002 -f157.79 -b12.5 -P0 -q1 -g37.2 -_1 -wsl000.00
start DSDPlus -F1 -r1 -e -m1 -i20002 -OM NUL

How many dongles do you have connected to the PC?

I have one, but the fmp24 window shows there are 2

 

[dave3825]

And if you open your windows device manager, how many dongle does that show?

You could try changing your fmp24.bat to use the first available dongle instead of it looking for dongle 1 of the 2 fmp24 is seeing.

change,
start FMP24 -i1 -o20002 -f157.79 -b12.5 -P0 -q1 -g37.2 -_1 -wsl000.00

to this
start FMP24 -i0 -o20002 -f157.79 -b12.5 -P0 -q1 -g37.2 -_1 -wsl000.00

Options:
-i0 Use first available RTL SDR device [-i0]
-i<num> Use RTL SDR device specified by <num> (1-255)

Perfect, that did it, thanks so much

Yes, it got your dongle to work, but does not explain why FMP24 is seeing 2 on your system when you have only one.
