[nRF7002 + nef5340] WIFI BLE Antenna Swiching

[DDYD1]

Hi there.

I am currently working on WIFI provisioning using BLE using nRF7002 and nRF5340.

The CPU structure of my custom board is based on the nRF7002DK. So I am testing using WIFI lesson 2 exercise 3 from nRF Dev academi.

I have one question. 

1. looking at the nRF5340 pins in that example, I am only using the nRF_radio_coex-swctrl 1 signal.
What is the process to change that nRF_radio_coex-swctrl signal to 2 signals, nRF_radio_coex-swctrl 0, nRF_radio_coex-swctrl 1. Is it just a matter of adding a pin?

It would be nice to know about them quickly.

Thank you!

Hello,

I recommend checking the WiFi-BLE coexistence sample. This sample demonstrates how the antennas are shared or how a dedicated antenna can be used along with coexistence. It is still a bit unclear why the CTRL signals need to be controlled in the way you described. You can find the coexistence section here.

Kind regards,

I checked out the articles you recommended.
While checking out Coexistence's documentation, I came across an interesting note.

Coexistence

Note: The behavior of SW_CTRL0/1 is programmable and dependent on the configured coexistence mode and switch control interface.

In what way can I program SW_CTRL0/1? If there are any examples or previous answers related to this method, please let me know.

I want to configure the antenna to use Wifi when SW_CTRL0 is High and BLE when SW_CTRL1 is High.
