Re: [Discuss-gnuradio] Delay determination between Tx and Rx signal for limesdr mini with help of gnu radio.

So, first of all:

never use "Throttle" in a flow graph with hardware.
In fact, GRC will *scream* at you that you shouldn't be doing that!

Then: I can't claim to have any knowledge of the limeSDR driver, but
unless that driver specifically allows you to start the TX and RX
streaming at the exact same instance: That delay is not a deterministic
value.

Best regards,
Marcus

> Hello Guys, I am having trouble to find the proper delay point between Rx and Tx signal while running the qpsk modulation scheme on gnu radio to my Limesdr mini board. While I am running the program through limesdr, I realize that it has a greater delay between (as expected). However, until now I am unable to find the proper amount of delay. I am changing the range of the delay from gui range(int type) to find the delay which will give me the synchronized Rx and Tx so that I could ensure that there is no missing data at the receiver side.
