Part Number: CC85XXDK-HEADSET

HI,

I could able to establish full duplex communication between master and slave. MICBIAS on master board is not available in the confguration tool to connect the external microphone, but could able to fix this issue with "aic3204_micBiasOnDualHeadset .ppwadd" provided in below e2e link

https://e2e.ti.com/support/wireless_connectivity/purepath_wireless/f/382/t/284987?CC85XXDK-headset-1-Master-2-slave-with-bidirectional-connect

But, when I am configuring as 1 master and 4 slaves mode (no bi-directional, only broadcast mode) then MICBIAS is not available in master to connect external microphone. Pls suggest to resolve this issue.

Thanks,
