nRF 5340 Audio DK - PHY coding

[Lars.Bjok]

Hello!

I am curently evaluating the nRF5340 Audio DK. I'm having trouble testing different PHY coding setting (2Mbps, 1Mbps, ,500kbps and 125kbps) using the nrf5340_audio application provided by Nordic Semiconductor. I am currently using three DKs one as a transmitter and two as receivers.

After investigating the issue, i've noticed that configuration such as CONFIG_BT_CTLR is not compatible with the DK. 

The goal for this evaluation is to see how different PHY codings affect the LE audio streaming. Any help would be greatly appreciated

Hi Lars,

Sorry for the delay.. 

The default for the Audio application is 2M PHY. You would loose half the bandwidth by going to 1 M PHY - it would also cost more power, since it takes longer (more radio time) to send the same message in 1 M PHY compared to 2 M PHY. Could you tell me why you need to change the PHY.?

Yes i understand that power efficency might be different. I want to change the PHY - configuration to test if the range that audio can be transmitted in the different configs between the 2M, 1M 500kbps and 125kbps. I dont see why you would keep these changes locked for the application.

I want to know if it's possible to change the to the different PHY - settings and if it's possible how would i do it on the nRF5340 Audio DK.

Regard,
Lars
