CC2564MODA: How to modify A2DP demo to connect with smartphone automatically

Part Number: CC2564MODA
Other Parts Discussed in Thread: CC2564

Hi,

My customer is implementing A2DP with below HW+SW.
HW: DK-TM4C129X
SW: http://www.ti.com/tool/CC256XM4BTBLESW

CC2564 is sink, smartphone is source.
Customer wants to modify the A2DP demo so that smartphone and CC2564 are automatically connected as soon as both devices are on.
I knew below changes are needed from original E2E thread.
- Store BD_ADDR and Link key in the flash
- Reload stored information and connect to the smartphone

But it is not clear how to implement above in the A2DP demo.
Could you specify which commands need to be added in which part of the code?

Thanks and regards,
Koichiro Tashiro

These changes are the same for any sample application. Here is one example.

This thread uses MSP430 as a host, so the similar flash read/write functions need to be implemented on the TM4C in your case.

Best regards,

Vihang
