rf_port_select does not work

Question

Good morning 
 for this 
 ret = iio_channel_attr_write(phy_chn_rx, "rf_port_select", rxcfg.rfport); 
 I get a -22 
 Other settings for the rx channel work 
 The 
 phy_chn_rx = iio_device_find_channel(phydev, "voltage0", false ); 
 gives the channel for rx. This one works. 
 
 Additionally is of value to assign settings to altvoltage0 or altvoltage1 for the PLUTO? It seems they are not available ... 
 
 Thank You 
 Pietro

Hi Travis 
 I changed the call to the read this way 
 err2 = iio_channel_attr_read_bool( iio_device_find_channel(phydev, "voltage0", true), "rf_bandwidth", &pluto_ad9361_phy_attrib.voltage0_out.filter_fir_en ); // wrong iio_strerror(err2, buf2, 200); err2 = iio_channel_attr_read(iio_device_find_channel(phydev, "voltage0", true), "rf_port_select", pluto_ad9361_phy_attrib.voltage0_out.rf_port_select, 20 ); // wrong iio_strerror(err2, buf2, 200); 
 Now all of the readings are working. But the difference is the channel is inlined every time rather than recycled from a variable. It should not make any difference but ... That's it. 
 Thank You

You are missing the dot "." at the end of the command. Needs to be: 
 iio_attr -u ip:pluto.local -c ad9361-phy .
