Hey guys we just got our new generation of our PCB’s back using the BC127 HD Module:
We are using 2 Knowles MICS
knowles.com/eng/content/down … +Rev+A.PDF
Only 1 works? If we cover the LEFT mic no sound is herd for far end caller, If we cover the RIGHT mic far end caller hears us fine… So Left works fine Right does not…
We have done the traces on the board back to the BC127 HD but only have one MIC… ( On all 7 boards we had created )
Is it possible its a license thing?
We have purchased this license ( 2-Mic Hands Free License - BCSW-CVC-HF-2M-Fx ) that goes along with the MAC of each module from Qualcomm and ran this command
license CVC=3465 57F8 42AE 7C91 8118
We also use these Commands:
SET NAME=Vehroot Shelf ( Last 4 )
SET PROFILES=2 0 3 0 2 1 2 1 0 0 1 0
SET HFP_CONFIG=ON ON ON ON OFF
SET DISCOVERABLE=1 0
SET CODEC=8 ( APTX-HD) - Matt, is this codec needed for aptX- HD as opposed to SET CODEC=??
We also run these commands for the best MIC volume:
CVC_CFG NB 0 14
2280 0000 1A00 8000 0000 80D0 0000 0000 0000 0000 0000 0020 0000 80D0
CVC_CFG WB 0 14
2284 0000 1A00 8000 0000 80D0 0000 0000 0000 0000 0000 0020 0000 80D0
Do you see anything here that would not enable the right NON working MIC?
