pi@raspberrypi:~ $ Look at ad9361-phy: there are limited controls on the second channel, i.e. no gain_control_mode, hardwaregain, rf_port_select values on voltage2 (RX2/TX2). I guess those are all linked to voltage0 (RX1/TX1)? Useful for MIMO only then?
Generally there is support for multiple channels, if you set https://github.com/pothosware/SoapyPlutoSDR/blob/master/PlutoSDR_Settings.cpp#L118 to "2" and recompile you should be able to stream both RX or both TX at the same time. E.g. setupStream() does recognize channels={0,1}.

2 years ago Interestingly https://wiki.analog.com/resources/tools-software/linux-drivers/iio-transceiver/ad9361#tx_attenuation_control talks about "attenuation/gain can be individually controlled for TX1 and TX2" at "voltage1 hardwaregain", but there is no voltage1 here, I assume it's the voltage2 channel, and there is no hardwaregain value.

2 years ago Ah! So you're saying the RX2 channel just has whatever gain the RX1 one has?
Also I did exactly that one line code change and recompile (1->2) before I opened the issue. I thought what I was trying was too naive because it looked like the data coming from both channels was the same. But maybe I got my observation wrong! Will look again.

2 years ago Yes, and most of the other settings too. IIO is the API. any value you don't find there is not an API setting.

2 years ago Hi @zuckschwerdt I have pluto+ with SoapySDRUtil --probe="driver=plutosdr" we have only one RX channel "numbered 0" :
----------------------------------------------------
-- RX Channel 0
----------------------------------------------------
Full-duplex: YES
Supports AGC: YES
Stream formats: CS8, CS12, CS16, CF32
Native format: CS16 [full-scale=2048]
Antennas: A_BALANCED
Full gain range: [0, 73] dB
PGA gain range: [0, 73] dB
Full freq range: [70, 6000] MHz
RF freq range: [70, 6000] MHz
Sample rates: [0.260417, 61.44] MSps
Filter bandwidths: 0.2, 1, 2, 3, 4, 6, 7, 8, 9, 10 MHz
but inside pluto device inside cd /sys/bus/iio/devices/iio:device0 we heve :
in_voltage0_gain_control_mode,
in_voltage0_hardwaregain ,
in_voltage0_hardwaregain_available ,
in_voltage0_rf_port_select ,
in_voltage0_rssi ,
in_voltage1_gain_control_mode ,
in_voltage1_hardwaregain ,
in_voltage1_hardwaregain_available ,
in_voltage1_rf_port_select ,
in_voltage1_rssi both RX port have their own parameters.
My Question, can i use the second channel RX2 using SoapyPlutoSDR ?
zuckschwerdt
commented
2 years ago The AD9363 is a 2x2 transceiver, but I wasn't aware that the second channel is connected in any hardware version. That "Pluto+" seems to be a no-name knock-off with some extra features (2nd channels, Gigabit ethernet).
You can change "getNumChannels" like written above to test things. But we are not explicitly using the "voltage1".
Can you give a dump of iio_info (iio_info --scan)?

No trigger on this deviceThanks. Interesting, so that really is a AD9363 (2 Rx, 2 Tx) and not the AD9364 (1x1) we otherwise see.
We should be able to detect the presence of the voltage1 in/out channel and then offer the second channel automatically.
I'll try to soon get a basic PR together. I'm not likely going to buy that hardware, so you'll have to help and test several version until this works ;)

2 years ago I see in sdrangle they have multiple channel. it's working for me. but the plugin is not complete and have a lot of bugs. also we can't receive IQ data from both channel at same time.
i'm thankfully and ready to test any code until it works.
zuckschwerdt
commented
2 years ago The branch https://github.com/pothosware/SoapyPlutoSDR/tree/feat-multichn should work now to select the second channel. I have not checked or implemented anything for both channels at the same time yet.

commented
2 years ago @moemuses did you have a chance to test the changes from branch feat-multichn?
moemuses
commented
2 years ago @zuckschwerdt, yes i'm ready. just tell be how exactly i can test it ?
zuckschwerdt
commented
2 years ago Do git clone https://github.com/pothosware/SoapyPlutoSDR.git
or change to an existing SoapyPlutoSDR folder and git fetch
then change the branch git checkout feat-multichn
now build and install as usual mkdir build ; cd build ; cmake .. && make && make install
moemuses
commented
2 years ago yes i mean what after make the project ? how can i test the second channel ?
zuckschwerdt
commented
2 years ago The driver should offer the second channel (and more antennas). You should be able to just switch to the second channel and use that. Perhaps connect an antenna to just one channel (RX1, the later RX2) and test if that works to receive data.
Dual channel likely does not work yet. Also I'm not sure if sample rate and frequency go to the selected channel correctly.

2 years ago perform SoapySDRUtil --probe="driver=plutosdr"
having 2 TX and 2 RX. "the master branch only display 1TX and 1RX"

Full freq range: [70, 6000] MHz
RF freq range: [70, 6000] MHz
Sample rates: [0.0651042, 61.44] MSps
Filter bandwidths: 0.2, 1, 2, 3, 4, 6, 7, 8, 9, 10 MHz
also when perform iio_readdev -u ip:192.168.2.1 -b 32768 -s 0 cf-ad9361-lpc | pv > /dev/null after change sample rate to 2.1Mhz, the normal Pluto make [8.01MiB/s] of data and Pluto+ have [16.0MiB/s]. maybe one IQ pair from RX0 and another IQ pair from RX1

2 years ago Yes, the data will be channels sample rate 4 (16 bit * I+Q). I only select a single channel, strange that it gives 16 MiB/s.
Can you run some application, maybe a UI like Gqrx and check if the received data waterfall matches the selected RX port? Maybe just touch the antenna at each ports in turn, and see if the interference matches that?

2 years ago the 16MiB/s come from iio library not Soapy library. the only UI application i can fine with dual channel receiving is sdrangel.
and the waterfall changes as i change the RX port. but also sdrangel work directly with iio not Soapy

2 years ago https://github.com/BatchDrake/SigDigger uses Soapy and allows to select the channel.

2 years ago in Sigdigger, regardless of using #channel number, alwayes same waterfall and data

2 years ago i'm trying this code
and change
SoapySDRStream *rxStream = SoapySDRDevice_setupStream(sdr, SOAPY_SDR_RX, SOAPY_SDR_CF32, NULL, 0, NULL);
to
size_t channels[2] = {0,1};
size_t numchannel = 2;
SoapySDRStream *rxStream = SoapySDRDevice_setupStream(sdr, SOAPY_SDR_RX, SOAPY_SDR_CF32, channels, numchannel, NULL);it's working normal when numchannel = 1. but when numchannel = 2 we get Segmentation fault after this function.
By the way when changing channels[2] = {0,1} to channels[2] = {1,0} its suppose to receive in another channel. but always receive channel number 0.

2 years ago I half expected that ;) But now we have test code I'll go on to add multi channel support. In a day or so.

2 years ago Good Luck !

2 years ago delete first two condition in PlutoSDR_Streaming.cpp
if (channel_list.size() != 2) // one RX with I + Q
return false;
if (buf_step != 2 * sizeof(int16_t))
return false;and it's working now !
i think we must change those condition to be dynamic with number of channel

2 years ago That's for direct copy and won't generally work. But something similar, yes.

1 year ago FYI, the latest hardware revisions of the original Pluto are also 2x2 now. The two new channels don't have an external connector, but there are internal connectors that can easily be connected: https://www.youtube.com/watch?v=ph0Kv4SgSuI
So this doesn't only apply to "Pluto+" anymore.

1 year ago Thanks! I need to go through the different channel copy cases mentioned above and add multi channel. And then we likely need separate rate/freq per channel.

2 months ago Any news on multi channel support ? There are many SDRs for today, based on ad9361/9363 with 2R2T mode. They are original Pluto, Chinese Pluto+, Chinese AntSDR. It would be great to add good multi channel support. As for me I used branch feat-multichn, however I can not make it work with new iio versions.

2 months ago I think the basics are there with the feat-multichn branch, but there are quiet some details around dependent settings and such. I only have a Rev.B and don't think I can finish this without the hardware to test.
I know the internal AD chipset permits a second RX channel---how difficult would it be to add support for this second channel? I have a Pluto+ (Chinese variant) with dual receive, and I was hoping to use the second channel in a calibration context with SoapyPower.
Any hints you could give would be much appreciated!
