Re: PlutoSdr TX support via SoapySDR
|
The other thing I discovered is that sdrangel only supports in TX mode the plutosdr via the? iio interfaces. Trying to TX via SoapySDR does not work either only RX does! Tx works with sdrangel only in direct iio mode... The symptoms are the same than QUISK, tx gain looks broken when using SoapySDR with the Pluto.
Obviously the reference is the way tx_sdr does it...?

I come back on this (frustrating) issue.
It seems some users are able to use their limesdr in TX mode with QUISK via soapysdr, so at least there is a positive news
As you know, TX does not work with the plutosdr, only RX? works.
The other good news is that with v 52 my plutosdr does not crash anylonger when I TX/
I have been doing some tests with tx_tool
The tx_sdr tools? allows to? play a .cu8 IQ file via SoapySDR in order to easily verify that the soapy hardware module for a specific hardware works. There is another codegen command tool that allows to easily generate IQ File to be played with tx_sdr
And yes,? soapyplutosdr works in TX mode with Tx_sdr in ly environment; I was able to generate a nice CW signal.
After comparing the behavior of TX_SDR with the one of QUISK, everything happens as if the TX GAIN in QUISK was broken? for the plutosdr. In other words,? it looks like it is always set to 0dB even if the user choses the max value of 89 in the QUISK menu.? If I can control the gain with tx_sdr quite accurately, it should also be possible with QUISK .....Maybe (?) you could have another look at the way the gain settings are implemented for the plutosdr in TX mode?
Many thanks? ?
