ignored device: wlan0 (Qualcomm Atheros - QCA9377) #303

Closed QuadTriangle closed 6 years ago

QuadTriangle commented 6 years ago 
./test-hardware-capabilities.sh
wlan0 supports P2P

I am trying it for some time. I don't know what is wrong on my side.

after enabling trace with sudo miracle-wifid --log-level trace:

INFO: miracle-wifid - revision 1.0 Nov  7 2018 13:45:26

DEBUG: ignored device: wlan0 (manager_add_udev_link() in ../../../src/wifi/wifid.c:122)

so, I modified the logic in wifid.c, now It shows:

Now, I can connect to the tv, but nothing happens:

sudo ./miracle-sinkctl

tv ask for my permission to add, I accepted. now, whenever I use connect 9e:8c:6e:52:67:cc, tv shows Miracle connected to the tv.

Now, my question is, How can I use my tv as an external monitor?

On, windows 10, I press Fn+F8, select tv name. It works without disabling wifi connected.

See #172. Using miraclecast as source is still a WIP

QuadTriangle commented 6 years ago

@albfan How about DEBUG: ignored device: wlan0 (manager_add_udev_link() in ../../../src/wifi/wifid.c:122)

I had to diable some line to get it working.


#ifdef RELY_UDEV
        // if (udev_device_has_tag(d, "miracle") && !lazy_managed)
            link_set_managed(l, true);
        // else
            // link_set_managed(l, false);
#else
        // if ((!interface_name || !strcmp(interface_name, ifname)) && !lazy_managed) {
            link_set_managed(l, true);
        // } else {
            // log_debug("ignored device: %s", ifname);
        // }
albfan commented 6 years ago

print out values for lazy_managed and interface_name.

As you are not passing --lazy-managed nor -i <interface-name> you cannot go to else, but you do, let's see what happens

QuadTriangle commented 6 years ago

I used ../configure --enable-rely-udev. udev rules didn't work somehow. I tried rebooting. I will figure it out.

FYI: sudo tee "${RULE_FILE}" &>/dev/null <<-EOF is enough. cat is useless and causes hanging.

albfan commented 6 years ago

Then if you rely on udev but do not tag your device it is ignored

cat is useless about what?

QuadTriangle commented 6 years ago

In res/write-udev-rule.sh you have used cat | sudo tee "${RULE_FILE}" &>/dev/null <<-EOF. according to comments of https://stackoverflow.com/a/20752440, the use of cat is useless, here. that's why it hangs and user has to press an extra enter to exit. I can confirm it works without cat |
