[nRF 9160DK, nRF7002DK] Wifi scan in nRF9160DK

[DDYD1]

To everyone who is interested in this ticket.

I'm using the nRF9160DK and nRF7002DK. I'm currently trying to scan Wifi using the nRF9160DK.

I'm referring to another ticket for that question, but it hasn't been successful.

Connecting nRF9160DK and nRF7002DK

I've linked the pin to be the same as that ticket.

Board	nRF9160-DK(P3 & P4)	nRF7002-DK (P24)
SPI CLK	P0.13	P0.17
SPI CS	P0.10	P0.18
SPI MOSI	P0.11	P0.13
SPI MISO	P0.12	P0.14
HOST-IRQ	P0.07	P0.23
IOVDD-CTR	P0.00	P0.31
BUCKEN	P0.01	P0.12

 I used  sample on nordic. "nrf/samples/wifi/shell"

and i used

west build -b nrf9160dk_nrf9160_ns -- -DSHIELD=nrf7002ek

This is the result of checking through the console.  

this .7z is my file for this function.

shell.7z

Any help is appreciated. Thank you!

Hi,

 

Did you also solder the solder bridges as explained in this post?

 RE: Connecting nRF9160DK and nRF7002DK for testing SCAN sample. 

 

Can you share a picture of your setup?

 

Kind regards,

Håkon

Soldered sb25 and sb20.

It is the form of the wire which I connected

[DDYD1]

I found the problem.

The connection between the two boards was faulty with the line corresponding to the IRQ. When I replaced the wire, I was able to get the Wifi signal normally.

And I have additional questions.

Wifi connection on nrf9160dk with nrf7002ek

In the ticket above, I saw that the connections between the nRF9160DK and the nRF7002EK said that they could detect Wifi, but could not send data. Is that still the case?

My goal is to eventually use LTE and WiFi to transmit data. LTE and WiFi are not used at the same time, and WiFi is disabled when LTE is connected.

I am glad to hear that you found the root cause.

Yes, there is not enough RAM available to run other Wi-Fi operations than scanning on the nRF9160.

 

Kind regards,

[DDYD1]

If so, is it possible to add additional RAM?

[Håkon Alseth]

Hi,

 

No, there is no nRF91xx device available that has more RAM.

Here is the officially supported features listed in a table:

I was able to see the following in the link you sent.

Wi-Fi feature support

From what I understand, if RAM is an issue, I think it can be done by lightening the code. However, in the case of the nRF9160, it was understood that it does not support functions other than WiFi scanning, regardless of memory.
