require websocket and https combine example

ChiragBhavsar

Hi,

I am using SDK v2.6.1.

Is there any course available on DevAcademy for WebSockets?

For WebSocket i take reference of v2.6.1/zephyr/samples/net/sockets/websocket_client,

when i try to give wifi credential using wifi connect -s <ssid> -k 1 -p <password> then i have got wifi: command not found so require to give wifi credential?or how we are able to see WebSocket reference code output,

I need an example that merges WebSocket and HTTPS. Could you also provide feedback on how to merge both into a single code?

    Hi,

    ChiragBhavsar said:
    I hope so you change ssid and password in below functon,also i used WIFI_SECURITY_TYPE_PSK for security

    I used the same wifi security type. The only changes were for wifi_ssid and wifi_password in the set_wifi_credentials_struct(). Are any other changes necessary?

    Best regards,

    Hi,

    We used the Ubuntu OS, but I don't think this should matter.
    Please verify the entered SSID and password using another device.
    Additionally, delete the build folder and recreate it for the nrf7002dk_nrf5340_cpuapp board.

    I don't thing so any other change necessary,
    On our side, using the same program, we are able to connect to Wi-Fi successfully.

    once please try with this program

    HTTP.zip

    Hi,

    After several tries, I was not able to consistently reproduce this issue. I was able to reproduce it only ones (after around 3 minutes of waiting). Here is my log

    Are you able to consistently reproduce this issue on your end?

    Best regards,

    yes from my end i am able to reproduce this issue consistently,

    in your log i am able to see that you are also not able to connect with websocket

    [00:03:53.470,916] <err> Lesson5_Exercise1: Cannot connect to IPv4 remote (-116)
    [00:03:53.471,374] <err> Lesson5_Exercise1: Cannot connect to echo.thingy.rocks: 80
    [00:03:53.471,466] <err> Lesson5_Exercise1: No IPv4 or IPv6 connectivity

    If possible, please suggest changes to the code from your side so that I can implement them and try to resolve this problem.

    Hi,

    I have managed to reproduce this issue only once. I expect for the error to be consistently reproducible. It seems that the application on my side is not able to connect to wi-fi network most of the time. 
    Can you make a minimal sample which would show the same error (which can be replicated) for us to look into?

    Best regards,
    Dejan
