Part Number: CC2564C
Hello together,
I have a problem with two parallel SCO links on the CC2564C and hope that someone can help me further. Starting situation, I want to run two parallel SCO link's via one BT module, the audio packets are transferred from a STM32F413 via I2S (PCM) to the module.
The following problem occurs:
When I pair two headsets freshly, I hear audio on both headsets (left channel on headset 1 and right channel on headset 2), so far ok. When I initially pair, I store the LinkKey_t data in the uC's flash and when an Authentication_Request_Event occurs (headset switched off and on again), I load the corresponding data from the Flash into the LinkKey_t struct and then call HFRE_Open_Remote_HandsFree_Port(). whereupon both headsets reconnect automatically. Both headsets connect perfectly.
From this point on I only have audio playback on one headset. The function HFRE_Setup_Audio_Connection() returns for both connections 0 but the corresponding event
HFRE_Audio_Connection_Indication returns Status: 0x0001 which means unknown error. When I turn off the working headset and restart the audio playback, I get the playbacks on the previously not working headset
Thanks for your Help and BR
