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,

    Is there any course available on DevAcademy for WebSockets?

    No, there is no course for WebSockets on DevAcademy.

    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,

    You could try to test "wifi connect" command using wi-fi shell sample.

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

    Can you provide more information about your application? Which problem are you trying to solve? What is your goal when combining https and websocket?

    Best regards,
    Dejan

    I used SDK v2.6.1 with the nrf7002dk_nrf5340_cpuapp board.

    I referenced the Wi-Fi shell example and merged its prj.conf file with the websocket_client prj.conf file.

    However, I encountered errors. If you have a working websocket_client example with Wi-Fi shell integration, please provide it.

    Can you provide more information about your application? Which problem are you trying to solve? What is your goal when combining https and websocket?

    >> I want to transfer and receive data from the server using HTTPS and WebSocket on the nrf7002dk_nrf5340_cpuapp board. I have implemented HTTPS code on this board.

    Below is my HTTPS code, could you guide me on how to integrate WebSocket code with it?

    Hi,

    It does not seem to be any problem with wi-fi connectivity but with subsequent http request. Could you provide monitor mode capture along with your SSID/passphrase details?

    Best regards,
    Dejan

    Hi,

    You can enable wi-fi monitor mode by for example following this link. 

    sudo iw dev
sudo ip link set wlp1s0 down
sudo iw wlp1s0 set monitor none
sudo ip link set wlp1s0 up
sudo iw dev wlp1s0 set channel 1


    You can also look at our Wi-Fi monitor sample.

    Best regards,
    Dejan
