First, let’s create a working BLE_UART_SERVER（串口透传） BLE_UART_SERVER（以下简称uart_server）是具备蓝牙串口透传功能且无安全要求的单连接示例。串口透传，指的是作为无线数据传输通道，蓝牙芯片将Uart上收到的数据不经任何处理 A connected peer such as a smartphone application can transmit data to the micro:bit, up to a maximum of 20 octets at a time by writing to the RX Characteristic. Are you not able to get this to work? If you look inside the discovery_complete(. Follow steps mentioned in the Running a Precompiled Example section. The server is insight-fully (lol) named "UART Hello World 2". Many embedded BLE chipsets provide a "UART emulation" over BLE GATT. Passing the connected peripheral from the array of scanned peripherals and referencing the service uuid to the peripheral when we want to access it from This solution demonstrates how to enable fast data transfer between Bluetooth Low Energy Microchip hardware and Android Phone App. Follow steps mentioned in of Running a Precompiled Example document; Open and program the Application Example Example code for interacting with a Bluefruit Bluetooth LE UART in an Android application. But since arduino and device can not be connected by wires, so I am trying to use bluetooth for communication. For more information about the UART Service and compatible devices, I recommend 在单连接的BLE_UART_SERVER示例里，串口数据是没有格式的，蓝牙收到的数据也是单纯的透传。但在多连接的场景下，为了对收到数据的来源进行标志，应用通过串口传送出去的蓝牙数据应当包含con_idx相关信息。 ble uart server ¶.
