五、应用原理图及说明模块简要工作过程说明：每次上电后蓝牙装置会自动开机并搜寻上一次连接过的设备，如果没有搜索到上次连接的设备，则会一直处于被搜索状态(配对状态)，这时可用手机等蓝牙设备搜索并连接该蓝牙装置。LED状态说明：①配对状态时，红蓝灯交替闪动②连接后待机时，蓝灯闪亮应用图一、1234󰀀󰀀󰀀󰀀󰀀󰀀󰀀󰀀󰀀󰀀󰀀󰀀󰀀󰀀L1DC110UFAORLED1BLUEU1MICNCNCBAT-INAudio_RAOMGNDGND12345678S2910S3S4BT12002314131211S5L20RVOL+R510KVDD-BTBNEXTPREVIOUSPLAY/PAUSES1VOL-AORC100.39UFAOLAOMAOL0.39UFR41KR32.2KAOM0.39UFC9LED2REDCH_LEDR7C8R920KR10C20KR1120KR836K20KC71UF1234U3LM4871SHUTVO28765C120.1UFC310UFVDD-BTLS1L1VDD-BTC210UFVDD-BTD1715161920182122ONKEYAudio_LAOMBYPASSGND+IN-INVDDVO1SPEAKERCLED-BLUELED-REDRSTVOL-/PREVIOUSPLAY/PAUSEVOL+/NEXTNEXTPREVIOUSVBUCKGNDBC410UFJ112CON25V电源输入CH_LEDA5VINRXTXC51054U2BT4054VCCGND/CHRG电池充电电路BATBATPROG35R63KC610UFS6VDD-BTON/OFFBT1BATTERYTitleSizeA4Date:File:10-Mar-2012Sheet of E:\\BT1200\\BT1200-NEW(V1.3).DdbDrawn By:4NumberRevisionAR22.2KR110K1VDD-BT1223第9页/共10页
