一.從機為另一款芯片藍牙模塊，Uuid分別為

Server_Uuid:

D973F2E0-B19E-11E2-9E96-080020F29A66

Tx_Uuid：

D973F2E1-B19E-11E2-9E96-9E08000C9A66

Rx_Uuid：

D973F2E2-B19E-11E2-9E96-0800200C9A66

使用Central例程，修改以下

uint8_t?server_uuid[16]=?{0xD9,0x73,0xF2,0xE0,0xB1,0x9E,0x11,0xE2,0x9E,0x96,0x08,0x00,0x20,0xF2,0x9A,0x66};
static?void?centralStartDiscovery(?void?)
{
//??uint8?uuid[ATT_BT_UUID_SIZE]?=?{?LO_UINT16(SIMPLEPROFILE_SERV_UUID),
//???????????????????????????????????HI_UINT16(SIMPLEPROFILE_SERV_UUID)?};
??
??//?Initialize?cached?handles
??centralSvcStartHdl?=?centralSvcEndHdl?=?centralCharHdl?=?0;
??centralDiscState?=?BLE_DISC_STATE_SVC;
??
??//?Discovery?simple?BLE?service
??GATT_DiscPrimaryServiceByUUID(?centralConnHandle,
?????????????????????????????????server_uuid,
?????????????????????????????????ATT_UUID_SIZE,
?????????????????????????????????centralTaskId?);
}

上述代碼執(zhí)行無法查詢到服務(wù)Handle，需要怎樣修改

二.如果在不知道對方Uuid的情況下，在通過Mac連接到從機設(shè)備后怎樣獲取uuid

待連接的藍牙芯片的UUID是128bit，CH58xcentral默認是16bit的，因此需要做修改：

可以留下郵箱，提供代碼參考。

您好，您留個郵箱，給您發(fā)發(fā)現(xiàn)所有服務(wù)的參考代碼。

問題已經(jīng)找到了，謝謝！還有個問題就是CH579M SWD調(diào)試必須先用WCHISP軟件設(shè)置使能"兩線仿真"么？因為我手頭的板子是沒有USB口的，沒法使用WCHISP軟件，如果我需要仿真該怎么辦？

代碼調(diào)試期間，啟用兩線仿真需要在上位機進原廠boot后操作。您板子上有接出UART1和PB22嗎嗎，使用UART1接口也可以進boot，PB22接GND同時串口4根線一起接上，再點擊啟用兩線仿真，也可以成功（串口識別BOOT不會有提示）。啟用SWD會提示有代碼泄漏風險，代碼調(diào)試完畢批量生產(chǎn)后不建議啟用。

我這邊還遇到一個問題，CH579M為主機可以和CH579M的藍牙模塊(從機)進行通訊，讀寫都正常.但是和BLUENRG1芯片的藍牙模塊沒法通訊，服務(wù)特性搜索如下，當寫入數(shù)據(jù)時提示W(wǎng)rite Error ：3，手機搜索BLUENRG1模塊如下，手機可以正常和BLUENRG1模塊通訊。請問我這邊出錯 的原因是什么，謝謝！

搜索代碼如下:

	uint8_t?result;
//??attReadByTypeReq_t?req;
	uint8_t?i;

		if((iFindChar?&0x03)?==?0x03)
??		centralDiscState?=?BLE_DISC_STATE_CCCD;	
	}
??else?if?(?centralDiscState?==?BLE_DISC_STATE_CCCD?)

}

在建立連接成功之后，可以直接根據(jù)handle值進行通信：

這個例程可以發(fā)我郵箱么，謝謝！個人信息保護，已隱藏

這里的類型如果是write no response，則做如下修改：
