说明:在学习蓝牙,仿照SimplePeripheral里面的CHAR4仿写了一个数组,利用BTool+HostTest联调查看效果,发现如下图:
如红框中所示,Uuid Description显示为Unknow,我在调试过程中曾经忘记修改simpleProfileAttrTbl,将其中属性表value部分误写为simpleProfilechar4UUID,发现这样错误着写反而功能正常,我改回simpleProfilechar6UUID之后反而不正常了,所有参数都不能读,会报错。simpleProfileAttrTbl如下:
static gattAttribute_t simpleProfileAttrTbl[SERVAPP_NUM_ATTR_SUPPORTED] = { // Simple Profile Service { { ATT_BT_UUID_SIZE, primaryServiceUUID }, /* type */ GATT_PERMIT_READ, /* permissions */ 0, /* handle */ (uint8 *)&simpleProfileService /* pValue */ }, // Characteristic 1 Declaration { { ATT_BT_UUID_SIZE, characterUUID }, GATT_PERMIT_READ, 0, &simpleProfileChar1Props }, // Characteristic Value 1 { { ATT_BT_UUID_SIZE, simpleProfilechar1UUID }, GATT_PERMIT_READ | GATT_PERMIT_WRITE, 0, &simpleProfileChar1 }, // Characteristic 1 User Description { { ATT_BT_UUID_SIZE, charUserDescUUID }, GATT_PERMIT_READ, 0, simpleProfileChar1UserDesp }, // Characteristic 2 Declaration { { ATT_BT_UUID_SIZE, characterUUID }, GATT_PERMIT_READ, 0, &simpleProfileChar2Props }, // Characteristic Value 2 { { ATT_BT_UUID_SIZE, simpleProfilechar2UUID }, GATT_PERMIT_READ, 0, &simpleProfileChar2 }, // Characteristic 2 User Description { { ATT_BT_UUID_SIZE, charUserDescUUID }, GATT_PERMIT_READ, 0, simpleProfileChar2UserDesp }, // Characteristic 3 Declaration { { ATT_BT_UUID_SIZE, characterUUID }, GATT_PERMIT_READ, 0, &simpleProfileChar3Props }, // Characteristic Value 3 { { ATT_BT_UUID_SIZE, simpleProfilechar3UUID }, GATT_PERMIT_WRITE, 0, &simpleProfileChar3 }, // Characteristic 3 User Description { { ATT_BT_UUID_SIZE, charUserDescUUID }, GATT_PERMIT_READ, 0, simpleProfileChar3UserDesp }, // Characteristic 4 Declaration { { ATT_BT_UUID_SIZE, characterUUID }, GATT_PERMIT_READ, 0, &simpleProfileChar4Props }, // Characteristic Value 4 { { ATT_BT_UUID_SIZE, simpleProfilechar4UUID }, 0, 0, &simpleProfileChar4 }, // Characteristic 4 configuration { { ATT_BT_UUID_SIZE, clientCharCfgUUID }, GATT_PERMIT_READ | GATT_PERMIT_WRITE, 0, (uint8 *)&simpleProfileChar4Config }, // Characteristic 4 User Description { { ATT_BT_UUID_SIZE, charUserDescUUID }, GATT_PERMIT_READ, 0, simpleProfileChar4UserDesp }, // Characteristic 5 Declaration { { ATT_BT_UUID_SIZE, characterUUID }, GATT_PERMIT_READ, 0, &simpleProfileChar5Props }, // Characteristic Value 5 { { ATT_BT_UUID_SIZE, simpleProfilechar5UUID }, GATT_PERMIT_AUTHEN_READ, 0, simpleProfileChar5 }, // Characteristic 5 User Description { { ATT_BT_UUID_SIZE, charUserDescUUID }, GATT_PERMIT_READ, 0, simpleProfileChar5UserDesp }, // Characteristic 6 Declaration { { ATT_BT_UUID_SIZE, characterUUID }, GATT_PERMIT_READ, 0, &simpleProfileChar6Props }, // Characteristic Value 6 { { ATT_BT_UUID_SIZE, simpleProfilechar6UUID }, GATT_PERMIT_READ | GATT_PERMIT_WRITE, 0, simpleProfileChar6 }, // Characteristic 6 configuration { { ATT_BT_UUID_SIZE, clientCharCfgUUID }, GATT_PERMIT_READ | GATT_PERMIT_WRITE, 0, (uint8 *)&simpleProfileChar6Config }, // Characteristic 6 User Description { { ATT_BT_UUID_SIZE, charUserDescUUID }, GATT_PERMIT_READ, 0, simpleProfileChar6UserDesp }, };
