ENOTSUP when trying to connect to wifi using T91X

This issue stems from nrf_modem_lib being used for socket creation, causing wpa_supplicant to fail to add the interface. I wrote up a deep-dive here: https://danielmangum.com/posts/nrf9151-wifi-station/

Issue can be addressed with setting CONFIG_NRF_MODEM_LIB=n.

Youssef Elbattah I was also interested in using the nRF9151 as the host for the nRF7002 on the Thingy:91 X. I hit the same issue as you did (-134 / ENOTSUP), and did some debugging to determine that it is due to the the nRF9151 defaulting to using the modem lib socket implementation. You can get the the Thingy:91 X working station mode with the nRF9151 as host by setting CONFIG_NRF_MODEM_LIB=n. I have added support in the wifi/sta example here: github.com/.../20303

Hi Youssef,

[quote user="Youssef Elbattah"]

Yes the scan sample works very well, but how can i connect my thingy91x/nrf9151/ns or thingy91x/nrf5340/cpuapp to Wi-Fi?

Unfortunately, I cannot purchase the nRF7002-DK, as I’m currently working on a project using the Thingy91 with LTE-M as the protocol to send data to the cloud. Now, I want to transition to the Thingy91x and add Wi-Fi as a protocol alongside LTE-M.

nRF91-series does not have enough RAM available to do other functions than wifi scanning.

nRF5340 has enough RAM and flash to do more advanced functions such as wifi STA and/or SoftAP, but the thingy91x board in general is only intended to show wifi scanning for location purposes, so there is not much support for the board itself in NCS. I see that you have a on-going thread with a colleague of mine to get wifi/shell up and running, so I suggest you follow up with any issues in that case.

Kind regards,

Håkon

Hi,

nRF91-series devices isn't directly supported for RAM hungry features like STA/AP mode. I would recommend that you obtain a nRF7002-DK to test all features.

Could you try the scan sample and see if that works?

Note the added CMAKE arguments here:

Kind regards,

Hi Håkon,

No, I'm the only one, and i am using thingy91x_nrf9151_ns.

Hi Youssef,

Do any of the stock wifi-samples work at your end?

What hardware are you using?

Kind regards,

Håkon

Hi,

Now when I attempt to reflash it I get only this.

Hi,

Can you share the whole log from boot?

I suspect -134 return is a following error due to a previous failed init/call.

Kind regards,

Håkon
