DECT NR+ coex Pins on DK Board

[schnitzlein]

HI there,

I like to configure and use the COEX Interface with the COEX Pins for DECT-NR+

on a nrf9151DK Board: https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/boards/nordic/nrf9151dk/doc/index.html#id5

Can you help me to do that?

COEX Interface is not there mentioned, but I can see it on the DK Board.

DOCS:

• https://docs.nordicsemi.com/bundle/ps_nrf9151/page/nRF9151_html5_keyfeatures.html
• https://docs-be.nordicsemi.com/bundle/ps_nrf9151/attach/nRF9151_PS_v1.0.pdf?_LANG=enus

prj.conf Flags should be:

1. ..
2. ..
3. ..

DTS file or overlay file should contain coex pin gpio or not?

I cannot find it in dts or dtsi file for nrf9151.

But the Pins on the Chip are:

But are they routed to the COEX Pin Header? Logic Analyzer is quite.

I used everything in the software side (assuming the wireing / routeing is okay) I know.
Please help!

kind regards

Hello,

do you intend to use other features on the DK, or just the DECT? If just DECT, then I don't believe COEX should be necessary.

Hi,

thanks for the quick response!
Yes, we are intended to use other things.
I found a solution with prj.conf and keyword + AT Commands there.

I can see it now with logic analyzer.

Thanks
kind regards
