HC-05最新資料,包括AT指令介紹,模塊介紹,串口調試助手,單片機例程,模塊的封裝等等模塊介紹:HC-05 藍牙串口通信模塊,是基于 Bluetooth Specification V2.0 帶 EDR 藍牙協議的數傳模塊。無線工作頻段為 2.4GHz ISM,調制方式是 GFSK。模塊最大發射功率為 4dBm,接收靈敏度-85dBm,板載 PCB 天線,可以實現 10 米距離通信。模塊采用郵票孔封裝方式,模塊大小 27mm×13mm×2mm,方便客戶嵌入應用系統之內,自帶 LED 燈,可直觀判斷藍牙的連接狀態。模塊采用 CSR 的 BC417 芯片,支持 AT 指令,用戶可根據需要更改角色(主、從模式)以及串口波特率、設備名稱等參數,使用靈活。設置一個為主機,一個為從機,配對碼一致(默認均為 1234),波特率一致,上電即可自動連接。HC-05 支持一對一連接。在連接模式 CMODE 為 0 時,主機第一次連接后,會自動記憶配對對象,如需連接其他模塊, 必須先清除配對記憶。在連接模式 CMODE 為 1 時,主機則不受綁定指令設置地址的約束,可以與其他從機模塊連接。
