Bluetooth• GPIO Configuration

– #define BT_GPIO_RESET 39 // GPIO_39 : PMIC reset– #define BT_GPIO_DSC 4 // GPIO_4 : to disconnect RFComm link– #define BT_GPIO_POWER 12 // GPIO_12: Power– #define BT_GPIO_DATASELECT 3 // GPIO_3: DataSelect

• Timer Duration Setting– kal_uint32 BT_INQ_TOUT_DUR = 10000; /* Inquiry time out duration: 10 sec */

• Limits the inquiry time of each Bluetooth device.– kal_uint32 BT_RING_TOUT_DUR=5000; /* Out-of-band Ring interval : 5 sec */

• The host sends AT+RING to the remote Bluetooth headset every 5 seconds while in the incoming call state.

– kal_uint32 BT_CMD_GUARD_TIMER_DUR = 20000; /* Screen Guard Timer duration: 20 sec */• Maximum time allowed for each progressing screen. If the requested action does not respond within

20 seconds, the MMI cancels the requested action and moves the BT core to the connectable state.– kal_uint32 BT_MAKE_IDLE_STATE_TIMER_DUR = 5000; /* make BT to go back idle state

duration: 5 sec */• Maximum time allowed for the CSR chip to enter the idle state. If the request to enter idle state is

not acknowledged by the lower layer (Layer 4), error handling is invoked. The idle state may be requested when performing the certain functions: the CSR BT chip must first be idle before executing the inquiry, pair or page function.

Bluetooth• BT Address and Name

– kal_uint8 MMIBT_DEF_MYBTADDR[] = { 0x12, 0x34, 0x56, 0x5b, 0x01, 0x02};– Default BT address. The format is as follows:

• LAP= 123456• UAP=5b• NAP=0102

– The BT address is displayed on the UI in the following format: NAP: UAP: LAP

– kal_uint8 MMIBT_DEF_MYBTFNAME[] = { 'M', 'T', 'K', 'B', 'T', 'D', 'E', 'V', '\0' };• Default Bluetooth device name.

– kal_uint8 MMIBT_DEF_TRBTFNAME[] = { 'N', 'o', ' ', 'N', 'a', 'm', 'e', '\0' };• Name to give to found devices which do not provide a device name for the Bluetooth

master device.

• External Interrupt for Host Communication Wakeup Signal– EINT_Registration(bt_chan,KAL_TRUE,bt_state,BT_EINT_HISR, KAL_TRUE);
