CC2564MODN: A3DPDemo_SNK connection faild

Part Number: CC2564MODN
Other Parts Discussed in Thread: CC2564

Hi there,

I am using CC2564MODN and STM32F407 DISCOVERY KIT to implement an wireless MP3 demo. The SDK is CC2564CSTBTBLESW-v4.2.1.1,and it's running successful with A3DPDemo_SNK example code.

and My iPhone(7,iOS12.4.1),PC(win10,CSR8510),can found the A3DPDemo_SNK. The trouble is,When I try to connect the SNK,it's failed.iPhone said that the SNK maybe OFF,and PC said that the SNK was connected successful while the SNK device icon in MY BLUETOOTH DEVICE form is gray,no BT sevice can found also(Normally I can found A2DP,SPP,etc.). Fig.2 is console output when PC pairing the SNK,and there is nothing when iPhone is paring.

What should I do? Did I do something wrong when I porting these example code adapted for STM3240G-EVL to STM32F407-DISCOVERY ? Looking forward to your reply!

THANKS!

Hi Roc,

If you're using an STM32F4 why did you have to port? Our Bluetooth stack for STM32 natively works with any STM32F4. The setup only changes when using STM3240G-EVAL MCU.

Hi Jesu,

Thank you for answering my question so positively.

After two days of hard work,Now my iPhone can connect to the SNK.

The key to solving the problem is FW. Please refer to this thread : e2e.ti.com/.../463080

I bought the CC2564MODN from TAOBAO,and than designed a simple PCB to install it. according to TI's datasheet,this module based on CC2564B,

but the FW read is 6.15 as the picture shows above.It seems like I bought a CC2564,not CC2564B.So,after updating the FW to 6.85,The development

process went smoothly.

I'm sorry that my English is too poor to describe these tech questions clearly.

THANKS,

Roc
