Hi all.
CC8520 can get multiple slaves?
e.g -> 1 Master(Only receive voice audio data from Slaves) 2 Slaves (Only transmitte voice audio data to one Master)
This project wireless microphone.
If this function possible where can I modify PPW command?
Thanks
Hi,
Yes, with CC852x you can have 2 slaves (4 slaves with CC853x).
To transmit from slave to master you need to select Upstream audio on both your Master and Slave(s).
Master:
Slave(s):
Audio channel(s) on Slave(s) can be selected under the Audio Streaming tab (Dynamic selection mechanism).

Dear sir.
Thank you for your reply.
I tried but Can not work two slave microphones.
Below are my PPW setting.
Dear sir.
I can not change I2S Channel Left. As you can see still Red color X box.
How can I change this function?
I think 2 slaves microphones should be setting I2S channel Left.
Two slaves One master pairing good but one slave no sound.
I want use two slaves microphones and one master speaker at the same time.
Thank you.
Hi,
Both microphones can't be using the same I2S channel Left (CC85xx Master can't mix the two channels together).
What you can do if you want to mix the two channels together is to do it in the audio codex. You can configure the codec so that it outputs a mix of left- and right input data:
To do this you need to do a Custom setup on your codec under that Audio Interface tab and then you'll get a new tab called Audio Device Customization

Dear Kim,
Application reference guide for AIC3204 can be found here:
