RTL SDR dongle with lower sample rate than 220KHz

[jeromebi]

Does anyone know if there is any way to set the sample rate of RTL SDR dongle (2832U) to a lower value than 220KHz ?

I am currently using RTL SDR 2832 USB stick V3. The default sample rate set in the code is currently 2.4MHz (code is giving "const int DEFAULT_SAMP_RATE = 2400000;").
I can set the sample rate to a lower frequency, but when I set it to a lower value than 220KHz, I got an error which seems to come from the RTL SDR dongle driver.

Is there any way to allow my RTL SDR dongle driver (RTL 2832U) to accept a lower sample rate than 220KHz, which seems to be the minimum accepted yet ?

Otherwise, are you aware of any other RTL SDR dongle than 2832U that would accept a lower sample rate (ideally lower than 125KHz) ?

Thanks a lot to anyone who can provide feedback about it.

Hi Jeromebi,
There used to be a set of tools on the rtl-sdr.ru site.
But they will only work with older versions of sdr#
V1500 and some earlier versions.
Please see picture.

Sorry,
forgot to show device sample rate dialogue box options.
