nRF9160 and nRF7002 Wi-Fi controller connection

[isilio]

I am in the process of designing a pcb with nRF9160 and nRF7002 to be able to use the network via LTE and / or Wi-Fi. In addition, I will use the GSM module for notifications.

I know that I must connect both modules (nRF7 and nRF9) with the QSPI bus, what about the nRF7 control signals?
The BUCKEN and HOST_IRQ pins are required and additionally I must have control over the time of switching on the voltage on the IOVDD pin in accordance with the documentation.
What about pins SW_CTR01, SW_CTRL1, COEX_GRANT, COEX_REQ, COEX_STATUS0? I know that they are used when we share the radio with bluetooth modules. Should I be concerned with them when connecting the nRF7 module to the nRF9 or should I leave them unconnected?

Hi Pawel,

There is actually one sample using nRF7002EK with nRF9160DK for WiFi location service.

nRF9160: Location — nRF Connect SDK 2.4.0 documentation (nordicsemi.com)

There is only SPI connection between them and SW_CTR01, SW_CTRL1, COEX_GRANT, COEX_REQ, COEX_STATUS0 pins on nRF7002 are left in unconnected state.

Best regards,

Charlie

Thanks Charlie for the reply.

I understand that the nRF7002EK overlay will solve the problem of turning on the power in hardware, but in my case I have to set the BUCKEN and VDIO pins at the right time?

Best regards,

Pawel
