Thanks I'll do that if I don't make significant progress on my own

Hello Frog ,

This case is a little old, so in case iain does not come back with a reply to you I would recommend that you open a separate ticket so that we may help you with the issue you are seeing.
If you do this, please make sure to include which nRF Connect SDK version you are working with, and the relevant modifications you have made to increase the TX power.

Best regards,
Karl

I find myself in a similar situation - I have an nRF5340 and an nRF21540 FEM. I've added an overlay for the network processor and added the pin configurations for the SPI and GPIO pins that control the FEM, but CONFIG_MPSL_FEM_ANY_SUPPORT isn't set.

Are you please able to share what the Sydney team suggested?

Hello again, Iain

I am glad to read that the Sydney team is helping you with this, but I would once again like to apologize for the delay you saw in the original response rate - this is far higher than our acceptable response time.

Please do not hesitate to open up a new ticket if you should encounter any other issues or questions in the future! :)

Best regards,
Karl

Hey Karl,

No worries at all, I should have realised you guys would be on summer holidays - I am in the southern hemisphere so it slipped my mind!

It is OK, the team in Sydney saw my post and have been in contact with me, so I am working through this with them.

Thanks again,

Iain.

Hello,

Thank you for your extreme patience with this. We are currently in the national summer holiday period here in Norway, and so the response time unfortunately is much longer than average. I apologize for the inconvenience.

Could you try to completely delete your last build folder, and then rebuild the project?
Please then share the log output from this build here in DevZone (using the Insert -> Text option), so that I may take a look.

For good measure, could you also confirm which LE Audio controller version you are using?

Once again I would like to thank you for your extreme patience with this.

Best regards,
Karl

Additional - essentially I am unable to complete stage 3 on this list, since this option is greyed out in Kconfig.

As well as this, I cannot add "CONFIG_MPSL_FEM_ANY_SUPPORT" manually in prj.conf, and there is no prompt for it.
