Red Pitaya ppm issue

[DrSDR]

using the ethernet red pitaya 125-14, it works fine for RX, however when i change the ppm field , i do not see the signal shift in freq.
it seems the ppm field has no effect on the red pitaya
redpitaya=192.168.1.100:1001 using gqrx software.
thanks

This appears to be a bug in gr-osmosdr. The redpitaya_source_c::set_freq_corr method updates an instance variable, but does not immediately retune the radio:

I expect that an update to the PPM value will take effect the next time the frequency is adjusted.

ok thank you, i will give that a try.
you are talking about the hardware center freq or the tuner offset freq ?

Hardware center frequency.

ok thanks, it worked, enter in ppm value, then change hardware freq, i saw the ppm correction get applied. red pitaya is now tuned up. thanks for the help.
