nRF5340 Audio Coded PHY

[GatCode]

Hi,

is there any way to enable the coded phy instead of 2M phy in the nRF5340 Audio application?

Thank you!

Hi, 

We haven't tested whether code phy can work for the ISO package or not, I will update after we have a trial.

Hi Amanda,

thank you very much! I'm looking forward to it.

Just to be sure, despite setting a higher SDU Interval, lower RTN and the bt_iso_chan_io_qos.phy to BT_GAP_LE_PHY_CODED, what else does one need to change (kconf, ...) to enable the coded phy in this ISO supporting controller in general? Because if you only change the things mentioned before, the the BIG creation will fail with error -5 = I/O error.

Thanks!

Hi Theo,

Amanda is on vacation at the moment. The error -5 should be solved by replacing  CONFIG_BT_EXT_ADV=y with CONFIG_BT_CTLR_PHY_CODED=y.

Hi Priyanka,

thanks for your answer but this doesn't make a difference. Especially given that the nrf5340_audio we are talking about is using the provided Nordic/Packetcraft controller.

Is there another kconfig option needed?

Thank you!
