How to enable FRS using Dock SDK??

[ShifangZ_26]

Hi Ivan,

1. The marco define in the SDK should be enabled.

/*******************************************************************************

* Enable PD spec Rev 3 support

******************************************************************************/

#define CCG_PD_REV3_ENABLE                          (1u)

#define CCG_FRS_RX_ENABLE                           (0u)

#define CCG_FRS_TX_ENABLE                           (0u)

>> The TX and RX should be enabled as per your requirements.

2. And you also need make a rising plus with Pin#20 if you are designing a FRS TX.

Best Regards,

Lisa

Hi, Lisa,

I enable below setting and trigger it by rising plus.

but i didn't see any CC packet sending.

#define CCG_FRS_TX_ENABLE                           (1u)

#define APP_FRS_TX_GPIO_PORT_PIN_P1     GPIO_PORT_2_PIN_5   //  Pin#20
