Problem with Wi-Fi Fundamental: Lesson 1 - Exercise 1

oscargomezf

Hi,

I’m trying to finish the first exercise of lesson 1, but when I save it to flash and run the binary, I get this error and I don’t know what’s causing it.

Could someone help me? I’ve simply exported the example mentioned in the instructions: Bluetooth LE Wi-Fi provision.

Thank you.

    Hi,

     

    These logs indicate that the application firmware is unable to communicate with the network core on the nRF5340:

    [00:00:03.515,136] <err> bt_hci_driver: Endpoint binding failed with -11
[00:00:03.515,136] <err> bt_hci_core: HCI driver open failed (-11)
Bluetooth init failed (err -11).

     

    Could you check if your flashed the merged image, or the sub-image? Make sure that the "build" catalog is selected in blue here, and not "ble" or "ipc_radio" before pressing "flash":

     

    Kind regards,

    Håkon

    Ok that's working right now, but I have another issue:

    It seems that the connection is done, but the App is trying to pair continuously:

    Hi,

     

    Great to hear that you got some progression on this issue.

    There should be a pop-up with a pairing notification from the android system after connecting, like this:

    Before you can fill in your SSID/password, and crypto option.

    Could you check if there is any permissions on that app that is denied?

     

    Please note that if using WPA/WPA2 mixed mode selection, then there is a known issue on NCS v3.1.x at this time, and you will need to cherry pick this fix:

    Kind regards,

    Håkon

    I am not able to change these permissions from my cell phone. I've tried to reinstall, and delete data app:

    Hi,

     

    Have you tried restarting your phone, and/or turning bluetooth on/off to see if this has any impact?

    Have you checked if there are any updates on your phone?

     

    Kind regards,

    Håkon
