I’m trying to change the gain reduction limit values from the range [20-59] to the range [0-59] using the function <b>mir_sdr_RSP_SetGrLimits(</b>) in order to use gain reduction values under 20.
Even though it returns <b>mir_sdr_Succes</b> , when i call the function <b>mir_sdr_SetGr(</b>) or <b>mir_sdr_RSP_SetGr() </b>aftrewards,<b> </b>they both return <b>mir_sdr_GainUpdateError</b><b> </b>and in the debug messages it says <i>mir_sdr_SetGr: ERROR: previous gain update not received (or timed out)</i><b><i>.</i>
</b>With both functions I have set the syncUpdate parameter to 0 and 1 however I always get the same error code and the new gain reduction value is not taken into account.
Here is the code for more details :
I first check if the gain reduction value input by the user is below 20
if it is the case I add 20 so it can be accpeted by the function mir_sdr_StreamInit (otherwise I get the ERROR: parameter out of range(absolute gRbd=10 LNAstate=0)
then i call mir_sdr_StreamInit with the corrected gain reduction value.
i change the gr limits to the range 0-59
i set the gain reduction value to the value requested by the user (which is below 20)
i call mir_sdr_SetGr() or mir_sdr_RSP_SetGr() .
