I am currently developing with the nRF9160DK and nRF7002DK. My project is to use the nRF9160DK as an external MCU to control the nRF7002DK's wi-fi and BT like a module.
This is the organization chart for my project.
The LTE board, the nRF9160DK, works as an external MCU, sending wifi scan commands to the 5340 every second.
I connected UART2 of the 9160 and UART0 of the 5340 crosswise RX,TX. On the 9160, I observed that the data came out correctly through the UART2.
To do this, I uploaded a firmware that sends data to the UART every second on the 9160 and a “wifi shell” example firmware on the nRF7002DK.
My expectation of the output was that it would automatically do a wifi scan and send the results to the terminal.
I honestly don't know what direction to take after this, and I'll try anything I can get my hands on.
Additionally, it would be great to have an example of wifi and BT coexisting, as I plan to use the nRF7002DK as a modem with BT and wifi coexisting in the future.
