客户需求，蓝牙未连接状态电源按键按下后发送开机广播
实现步骤
1.新建蓝牙广播包，格式按照客户要求，创建位置与advdata[]相同
static uint8 adv_power_on[] = { // flags 0x02, // length of this data GAP_ADTYPE_FLAGS,//0x01 GAP_ADTYPE_FLAGS_BREDR_NOT_SUPPORTED,//0x04 // service UUIDs 0x03, // length of this data GAP_ADTYPE_16BIT_COMPLETE, LO_UINT16(HID_SERV_UUID), HI_UINT16(HID_SERV_UUID), // appearance 0x03, // length of this data GAP_ADTYPE_APPEARANCE, LO_UINT16(GAP_APPEARE_HID_KEYBOARD), HI_UINT16(GAP_APPEARE_HID_KEYBOARD), // local name 0x0D, // length of this data GAP_ADTYPE_MANUFACTURER_SPECIFIC, // AD Type = 0xFF 0X5D,0X00,0X03, 0X00, 0X01, 0X00, 0X00, 0X00, 0X00, 0X00, 0X00, 0X00 // name };
2.创建函数发送蓝牙开机包，在hidkbd.c中加入以下代码并在.h中声明
void key_power_on_advert(void) { GAPRole_SetParameter( GAPROLE_ADVERT_DATA, sizeof( adv_power_on ), adv_power_on ); GAPRole_SetParameter( GAPROLE_SCAN_RSP_DATA, sizeof ( scanData ), scanData ); // set adv type uint8_t param=GAP_ADTYPE_ADV_IND; GAPRole_SetParameter( GAPROLE_ADV_EVENT_TYPE, sizeof(uint8),¶m ); uint8 adv_param = TRUE; GAPRole_SetParameter( GAPROLE_ADVERT_ENABLED, sizeof( uint8 ), &adv_param ); ble_LED_display_handle(POWER_ON_EVENT); }
3.修改 ble_LED_display_handle（）函数如下
static uint16 led_power_on_count = 0; void ble_LED_display_handle( uint16 event_id ) { switch (event_id) { case ADVERTISING_DISPLAY_EVENT: if( hidDevGapState == GAPROLE_ADVERTISING ) { if(led_flash_count == 0){ led_disp_cfg_t cfg; cfg.retention = 1; cfg.flash_loop = ADVERT_TIME/2; cfg.on_period = 200; cfg.off_period = 200; led_disp_start(cfg); } if( (led_flash_count++) < ADVERT_TIME ) { osal_start_timerEx(hidKbdTaskId, ADVERTISING_DISPLAY_EVENT, 200); } else { led_flash_count = 0; osal_start_timerEx(hidKbdTaskId, DISABLE_BLE_ADVERT_EVENT, 200); } } else { led_flash_count = 0; led_disp_stop(); if( osal_get_timeoutEx( hidKbdTaskId, ADVERTISING_DISPLAY_EVENT) != 0 ) { osal_stop_timerEx( hidKbdTaskId, ADVERTISING_DISPLAY_EVENT ); } } break; case FACTORY_RESET_DISPLAY_EVENT: break; case IR_DISPLAY_EVENT: break; case POWER_ON_EVENT: LOG("POWER_ON_EVENT\r\n"); if( hidDevGapState == GAPROLE_ADVERTISING ) { if(led_power_on_count == 0){ led_disp_cfg_t cfg; cfg.retention = 1; cfg.flash_loop = ADV_POWER_ON_TIME/2; cfg.on_period = 200; cfg.off_period = 200; led_disp_start(cfg); } led_power_on_count++; if( (led_power_on_count) < ADV_POWER_ON_TIME ) { LOG("led_power_on_count++\r\n"); osal_start_timerEx(hidKbdTaskId, POWER_ON_EVENT, 200); } else { led_power_on_count = 0; osal_start_timerEx(hidKbdTaskId, DISABLE_BLE_ADVERT_EVENT, 200); } } else { //led_power_on_count = 0; led_disp_stop(); if( osal_get_timeoutEx( hidKbdTaskId, POWER_ON_EVENT) != 0 ) { osal_stop_timerEx( hidKbdTaskId, POWER_ON_EVENT ); } } break; default: break; } }
4.HidKbd_ProcessEvent中添加POWER_ON_EVENT
if(events & POWER_ON_EVENT) { ble_LED_display_handle(POWER_ON_EVENT); return ( events ^ POWER_ON_EVENT ); }
5.在按键中断中添加 key_power_on_advert 添加可自己定义，我定义的是在按键松开时发送开机广播包
case BSP_BTN_UP_TYPE: KEY_LOG("[key]:%02d rel\n", key_index); start_enable_latency_event(); key_press_flag = FALSE; if( key_index <= 15 ) { if( get_hidDevConnSecure_value() == TRUE ) { if( get_ir_sending_mode() == true ) { ir_sending_stop_handle(0); } if( key_index== KEY_INDEX_AUDIO ) { VOICE_Stop(); } else { bt_key_code_sending_over_handle( key_index ); } Send_BTkey_flag = FALSE; } else { if(key_index==KEY_INDEX_POWER) { LOG("send power on adv"); key_power_on_advert(); } if(Send_BTkey_flag) { Send_BTkey_flag = FALSE; led_disp_on_off_ctrl(LED_OFF); if( key_index == KEY_INDEX_AUDIO ) { LOG("disconnect_voice_stop"); disconnect_voice_stop(); } } if( get_ir_sending_mode() == true ) { ir_sending_stop_handle(0); } } } if(battMeasure()<=20) { led_low_power_send(); } break;
