Win 10: Connection couldn't be established #54

Closed Strajuck closed 4 years ago

Strajuck commented 4 years ago

My Windows 10 source, recognizes the raspberry as a wireless display, but it can't establish a connection between them. Can anyone tell me what the issue is?

I followed all the advice given in the readme.

Regards and thanks for your help in advance

@Strajuck Ensure that BusyBox is installed on your pi. This was an issue for me. sudo apt-get install busybox

homeworkc commented 4 years ago

What is the output of the terminal? What is your system (Pi 3 a/b/b+ or 4, using built-in wifi)? Did you downgrade the wpasupplicant package? Did you do a reboot after downgrading?

Strajuck commented 4 years ago

@165plo The most recent version of Busybox is installed on my pi.

@homeworkc The terminal displays: Selected interface 'p2p-dev-wlan0' Available interfaces: p2p-dev-wlan0 wlan0 Selected interface 'p2p-dev-wlan0' OK Selected interface 'p2p-dev-wlan0' OK Selected interface 'p2p-dev-wlan0' OK Selected interface 'p2p-dev-wlan0' OK Selected interface 'p2p-dev-wlan0' OK Selected interface 'p2p-dev-wlan0' OK Selected interface 'p2p-dev-wlan0' OK 5 DIRECT-uF aa:4d:54:d4:c6:85 [DISABLED][P2P-PERSISTENT] =5
Selected interface 'p2p-dev-wlan0' OK Selected interface 'p2p-wlan0-0' Available interfaces: p2p-wlan0-0 p2p-dev-wlan0 wlan0 Selected interface 'p2p-wlan0-0' Available interfaces: p2p-wlan0-0 p2p-dev-wlan0 wlan0 p2p-wlan0-0 The display is ready Your device is called: lazycast_on_raspberrypi PIN: 31415926

I am also capable of selecting the device on my windows 10 computer. But if I enter the passcode, nothing happens. I am using a Raspberry Pi 3b with integrated wifi. And I did reboot and downgrade wpasupplicant.

Okay, here is another test. Run all.sh. After the PIN number is shown, open another terminal and run sudo wpa_cli. Then try to select the device on the computer and see what the output of wpa_cli is.

Strajuck commented 4 years ago

It just says "Selected interface 'p2p-wlan0-2' and "Interactive mode". There is no other output given...

homeworkc commented 4 years ago

What about running sudo wpa_cli first then run all.sh? Also, I found that sometimes installing NetworkManager helps. You can find the instruction here. If you find that your DNS does not work (it may take a while for this to happen) after installing NetworkManager, try sudo systemctl stop systemd-resolved. (See here for details.)

If i proceed with sudo wpa_cli first and then run all.sh it outputs the following:

Interactive mode

<3>CTRL-EVENT-SCAN-STARTED <3>P2P-FIND-STOPPED <3>P2P-GROUP-STARTED p2p-wlan0-0 GO ssid="DIRECT-uF" freq=2462 passphrase="vpuVvXMP" go_dev_addr=22:e4:94:12:df:83 [PERSISTENT] <3>CTRL-EVENT-SCAN-RESULTS <3>CTRL-EVENT-SCAN-RESULTS > Installed the other network manager. And it worked. Thanks a lot for helping me fix the Issue, i really appreciate your help!
