[nRF7002 + nef5340] WIFI BLE Antenna Swiching

Hello,

I am looking in the latest NCS Documentation and still cannot find any on this API you mentioned was coming for configuring SW_CTRL0/1.
Also just to confirm when the BUCKEN pin on the NRF7000 is low do the SW_CTRL pins go to high impedance or drive 0?

Thanks,

Dawson

Hello,

I received some information on this issue. Programming SW_CTRL0/1 is more than just adding a pin; it requires some development to create an API that can be called to achieve this. We are working on it and will be able to include this API with the NCS 3.0.0 release.

Kind regards,
Abhijith

Hello,

Apologies for the delayed response. I just wanted to let you know that I am still working on this case. However, I am not entirely sure about your question, so I am checking internally regarding this query. I hope to have a response for you early next week, and I will update you as soon as I receive more information.

Thank you for your patience.

Kind Regards,
Abhijith

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.

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,

Sorry for my late reply

What I am trying to accomplish is
1. use the wifi and BLE antennas as coexistence using swctrl 0, swctrl 1.

Why do I need two swctrl signals: the coexistence antennas of the Wi Fi and BLE antennas on the custom board I use control Wi Fi and BLE via two signal lines. For this purpose, two signal lines are required.

Hello,

Sorry for getting back to you late. I am a bit confused about the question. Could you clarify what you are trying to achieve here or why you need two swcntrl signals? If you look at the nrf7002dk_nrf5340_cpunet.dts and nordic,nrf70-coex.yaml files, you will see that only one pin is assigned for this.

Kind regards,

I bulid that example into VScode and then checked it with Devicetree using the GUI.

I did not use overlay in that file.

Hello,

[quote user=""]looking at the nRF5340 pins in that example, I am only using the nRF_radio_coex-swctrl 1 signal[/quote]

Where exactly did you find the nRF_radio_coex-swctrl 1 signal? Can you provide me with the link? Are you referring to the coexistence of short-range and other radios?

Kind Regards,

Abhijith
