[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,

1. Is UMAC's role related to the MAC address I think is needed for the Wifi connection?

No, it is the universal medium access control, which is also mentioned in the product specification.

It is basically the firmware running on the nRF7002 that the host controller is trying to interface. The errors are printed because the nRF9160 is unable to communicate with the 7002 device.

2. Is UMAC stored in the same place as the flash memory of nRF7002DK?

It is running on the nRF700x device, but it is interfaced from the host controller, as shown here (picture from the PS):

I do likte this but still can't work 

You need both kits powered when doing this, and you need to erase the firmware running on the nRF5340 host controller, located on the nRF7002-DK.

This is done by using nrfjprog:

nrfjprog -e -f nrf53

 

Kind regards,

Håkon

I supplied the power as shown in the picture above.

After that, the command was used to clear the nrf53 inside and proceed.

it failed, but I got a different result.

Now I think both boards are powered on. But I still get a Timeout error related to UMAC init. Is there anything else I can do?
