Thanks for your response. No a simple reset should be fine. I did restart the computer which should reset the LimeSdr USB, but that didn’t do the trick.
I don’t think there is a reset button on the LimeSdr USB is there? Or is there a jumper pin which i need to flip and back?
Maybe i should wait a few seconds between disconnecting the USB 3.0 and reconnecting it?
It could be the software suite(srsRAN) not switching back to the internal reference once it locks to an external reference. Have you heard something like this where the application refuses to go back to internal reference once its find an external reference?
I tried GQRX for good measure to see if its receiving anything after i did the restart and it was working just fine(without external reference connected).
Also, i followed the following articles and posts to connect an external reference. But none of them tell on how to go back to the internal reference.
