Wifi setup command doesn't work in CygWin

pftg4 opened this issue · comments

i read the docs i'm on a windows machine downloaded

cygwin and typed command below

echo -n "{"psw": "YOUR_WIFI_PASSWORD","ssid": "YOUR_WIFI_SSID","t": "wlan"}" | nc -cu 192.168.1.1 7000

as written in the docs replacing my wifi info

it it says there is no such command so i searched netcat docs and indeed there is no cu comand

did i miss something

thanks

The command was tested under macOS, so there might be a difference in netcat options. Try using nc -Cu (capital C) instead.

The required netcat options are:

  • Send CRLF as line-ending
  • Use UDP instead of the default option of TCP

Please let me know if this fixes the issue.

hi arthur thanks for quick reply

the capital c did the trick but the cursor just jumps to next line and flashes i assume it is trying to connect to the ac??

i reset the wifi module on ac then connected to the ac network greexxxxx and ran the command

but nothing not sure what i am doing wrong would love to set this up and thanks for the hard work

The basic idea of the command is to echo a JSON payload, pipe it into nectat and send it using UDP.

The flashing newline means there might be something wrong with the syntax, probably with the echo command (wrong option or a quote left open). Unfortunately, I can't help you beyond that.

If you find a command that works, please post it here for others!

quick update windows android and my daughters MacBook air all do the same thing just jumps down one line and flashes I assume it cannot connect no errors just sits there on all platforms so not sure what i'm doing wrong?????

thanks

I just tested the original command (below) on my macOS terminal and it works. Try to run the following on the MacBook:

echo -n "{\"psw\": \"YOUR_WIFI_PASSWORD\",\"ssid\": \"YOUR_WIFI_SSID\",\"t\": \"wlan\"}" | nc -cu 192.168.1.1 7000

UDP messages are fire-and-forget so it won't wait for a response and should simply finish.

To my understanding the ac should then come out of ap mode and log on to my network correct??? so we Control it via pi so it has to be on same network

same results as before i took quite a few pictures to show you but github won't let me upload

thanks dave

How you make the AC connect to your WiFi doesn't matter, e.g. you can use the dedicated mobile app for that.

commented

yeah no matter what I do it won't connect to my wifi with that command or with the app i have reset wifi module many times I can log into the ac with laptop but not sure what I do when i'm in the command doesn't work for me just drops to next line and keeps flashing don't know it that is finished or can't do the command i get no feedback at all to know if the command is wrong or ac won't do what i tell it

is there another way I can do this ????

thanks

I'm sorry, but I have no access to a Windows PC to look into this. Did you finally manage to fix the command for CygWin?

commented

nothing I try works tried with mac as well you wrote above this will give me no indication whether it worked or not so there is nothing to troubleshoot sadly it just doesn't work for me glad it worked for you but this doesn't work here
