Tool/software: Starterware

Our plat employee the stm32f407, HCI have could connected to cc2564. And the cc2564modaem can find the headset, inquiry -> pair x -> pincoderesponse 0000-> servicediscovery x 11 -> openaudiogatewayclient 1 1-> manageaudio 1 , then the headset led's status indcated blue flash. We load the audio by codec connected to cc2564modaem' pcm port, but the headset have no voice yet. Would you like to give our some suggests on the audio carriage? What configure we have ignored? Tks!

R11 have been removed on CC2564modaem board, the module's PCM_CLK and PCM_FSYNC isn't presented on to the pin. In general, the paired headset status,the two leds flashing Alternately change to one led flashing after openaudiogatewayclient had been issued. the IAR import to HFPAGDemo workspace. Would you give any seggest to set the cc2564 as master and make it send the FSYNC and CLK? How we could load the codec voice stream to the cc2564?

Do, have external codec connected to the STM board? I believe, external codec is the master of the PCM clock in STM32F407 environment. So, please make sure PCM and FSYNC clocks are coming from the external codec..

Thanks

Yea, PCM and FSYNC clocks are coming from the external codec, R18 0 Ohm is place again to shield the debug port's PCM. cc2564 module still have no PCM clock even if those PCM's signal is off. PCM and FSYNC come from the module is expected.

Thanks!
