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:

[Håkon Alseth]

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,

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

[Håkon Alseth]

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

[oscargomezf]

Yes, several times.

[Håkon Alseth]

Could you share which phone you have, and which android version is installed? I will need this in order to report a bug internally to the mobile group team.

 

Kind regards,

Håkon

[Håkon Alseth]

Thank you for sharing.

I will report this internally to the mobile group team.

 

Kind regards,

Hi Oscar,

Just in case... Have you tried with other phone? Does it work ok?

Thanks,

Mikel

Hi Mikel,

Yes, I have checked with other Oppo (Reno 12 FS) with Android 15 but with the same behaviour.
