Connecting nRF9160DK and nRF7002DK for testing SCAN sample.

[Gova]

Dear team,

I am trying to test Wi-Fi scan sample with the kits nRF9160DK and nRF7002DK. I am aware of nRF7002-EK and it is taking time to get it. Since we are running out of time, we are trying to accomplish the same using previously said two DKs.

In the hardware,

I saw the ticket  nRF9160 and nRF7002 Wi-Fi controller connection and made the following connections.

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

Also I soldered the SBs from SB20 to SB25 on nRF7002DK.

I DID NOT remove the 0R Resistors R26-R31.

I powered both DKs seperately using USB cables.

Now, the firmware part.

I programmed nRF5340 on nRF7002 DK with basic blinky, to make sure it is not using any other GPIOs, that we are using.

Now, I opened the Wi-Fi Scan sample in VS Code.

Toolchain used is v2.4.1.

I added the overlay-scan-only.conf, nrf9160dk_nrf9160_ns.overlay under boards.

I added -DSHIELD:STRING="nrf7002ek" and -DOVERLAY_CONFIG=overlay-scan-only.conf under CMake arguments in build configuration.

Build is successful, but when programmed, no UART output is seen.

Please help.

Thanks a ton in advance.

Also, can we have nRF9160 in STA mode using nRF7002? Why is it available only for scanning in SDK?

Hakon,

Sorry, there was a mistake in sharing the dts file. I have edited the previous reply and now it is correct. Sorry for the mistake.

Thanks.

Hi,

 

I took one of my nRF7002-DK v1.0.2, soldered SB20-25 and connected according to your setup:

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 a nRF9160-DK v1.0.0

Took the samples/wifi/scan sample, and configured/compiled it with:

west build -b nrf9160dk_nrf9160_ns -- -DSHIELD=nrf7002ek

 

And here's the output:

[00:00:00.416,931] <inf> wifi_nrf: SPIM spi@b000: freq = 8 MHz

[00:00:00.416,992] <inf> wifi_nrf: SPIM spi@b000: latency = 0

[00:00:00.500,213] <inf> wifi_nrf: Firmware (v1.2.8.1) booted successfully

Starting nrf9160dk_nrf9160 with CPU frequency: 64 MHz
Scan requested
Num  | SSID                             (len) | Chan | RSSI | Security | BSSID
Long list of AP's in my area

Scan request done

 

Please note that it is a requirement to erase the firmware running on the nRF7002-DK (ie. the nRF5340):

nrfjprog -e -f nrf53

 

This is to ensure nRF5340 releases the GPIOs in question, so that the nRF9160 can drive them.

 

Kind regards,

Håkon

Hi Hakon,

Thanks for your reply.

I also connected the same way, between the boards.

I erased the nRF7002-DK using nRF programmer's Erase All feature.

I used scan sample from 2.4.2 SDK.

I selected nrf9160dk_nrf9160_ns board after selecting Nordic boards radio button.

I added only the -DSHIELD=nrf7002ek C Make Argument in VS Code's build config window.

I programmed the board and got error in the output.

Please help me.

Hi,

 

Could you try to reduce the SPIM speed to 1M and see if this helps? Long wires add extra capacitance to the SPI signals, and lowering the speed can help rule out that factor.

 

1. Which version of the nRF9160-DK are you using?

2. Which version of the nRF7002-DK are you using?

 

Kind regards,

Håkon
