BLE_CableReplacement不起作用的原因？

214 BLE

问答对人有帮助，内容完整，我也想知道答案 0 您好，我正在尝试在两个 P-Nucleo_wb55 板之间建立通信。一旦我使用 cubeIDE 示例刷新固件 (STM32CubeRepositorySTM32Cube_FW_WB_V1.12.1ProjectsP-NUCLEO-WB55.NucleoApplicationsBLEBLE_CableReplacement) #define GATT_CLIENT 0//1//chaning this for client/server roles 我在我的 PC 上打开串行终端（putty 或 realterm），COM 端口可见但它们没有响应.... 0

答案对人有帮助，有参考价值 0 来自 STM32CubeRepositorySTM32Cube_FW_WB_V1.12.1ProjectsP-NUCLEO-WB55.NucleoApplicationsBLEBLE_CableReplacementreadme.txt @par How to use it ? This application requires having the stm32wb5x_BLE_Stack_full_fw.bin binary flashed on the Wireless Coprocessor. If it is not the case, you need to use STM32CubeProgrammer to load the appropriate binary. All available binaries are located under /Projects/STM32_Copro_Wireless_Binaries directory. Refer to UM2237 to learn how to use/install STM32CubeProgrammer. Refer to /Projects/STM32_Copro_Wireless_Binaries/ReleaseNote.html for the detailed procedure to change the Wireless Coprocessor binary. 做到了 In order to make the program work, you must do the following: - Open your preferred toolchain - Rebuild all files and load your image into target memory 我使用 STM32CubeIDE v1.7.0 并成功构建和闪烁 Two STM32WB55xx boards are used one acting as GATT client, the other as GATT server. Both boards need to be compiled with different code by changing the #definitions in app_conf.h #define GATT_CLIENT 0/1 /* 1 = Device is GATT Client, 0 = Device is GATT Server / If device is GATT client, it is also central (defined in ble_conf.h) If device is GATT server, it is also peripheral (defined in ble_conf.h) 这样做并闪现了两个不同的图像，每个 wb55 一个* Open VT100 Terminals on Client and Server side. Connected to ST Link COM port @115200. 不知道 VT100 终端是什么，我正在尝试使用 putty 和 realTerm，可以吗？它不是 Once the code is downloaded on the two STM32WB55xx boards and executed, the modules are initialized. The Peripheral device (Cable Replacement Server) starts advertising, The Central device (Cable Replacement Client) scans and automatically connects to the Cable Replacement Server. Once connected, the Cable Replacement Client (GATT Client) starts to search the Cable Replacement Services & Characteristics. The above phase takes about 5 seconds, after that period Reception and Transmission parts will appear in the Client and Server VT100 Terminals. On each VT100 Terminal windows you can type the text you want to send and receive the text sent by the connected device. To summarise: 1 User write text on GATT Server VT100 Terminal 2 Server ----------- Notification packet ------> Client or 1 User write text on GATT Client VT100 Terminal 2 Client ----------- Wtite Command packet ------> Server 它实际发生的是这个我输入 ascii“u”，然后 stlink 回答了一个奇怪的字符串（在另一个模块中没有任何反应）好的，我意识到 VT100 不仅仅是串行终端程序的名称，这是一个完全不同的古老 uart 协议 yeey（它以八进制定义）所以更多的逆向工程，我开始相信这不会是一个非常有用的例子所以如果我发送字符“t” 我会得到回复“e[32;23Ht”，这看起来像 https://vt100.net/docs/vt100-ug/chapter3.html “e[”等同于“ESC[”（CSI）最后一个 H 是最终字符其位组合终止转义或控制序列的字符。参数字符串有两个参数，它们在这个函数中构建 void PosCur(uint8_t iX, uint8_t iY) { char szCtrl[30] = "33[01;01H"; szCtrl[3] = (int8_t) ((iY % 10) + '0'); szCtrl[2] = (int8_t) ((iY / 10) + '0'); szCtrl[6] = (int8_t) ((iX % 10) + '0'); szCtrl[5] = (int8_t) ((iX / 10) + '0'); UartTransmitStr(szCtrl); }
