BM64无法将URAT数据发送到配对设备

嗨，Phil，可能是个愚蠢的问题，你检查过模块默认波特率吗？我摔跤的BM78有115200的缺欠。欢呼杰夫。

    Hi Phil,
Might b a daft question, have you checked the modules default baud rate? The bm78 I'm wrestling with has a default of 115200.
Cheers Geoff

有两个问题需要帮助，我使用的是类似的BM62。你使用的是评估板还是内置到自定义板上？如果使用评估板，你是通过USB端口还是UART报头（J6）连接？你使用微芯片提供的PC程序连接到BM64 UART吗？正如杰夫所说，BMUD默认值为BM64的115200。三个重要引脚是：MFB-HeIAN-LUPP2O0-高，如果您通过EVE板的USB端口连接，您应该能够看到115200 Bad的通信，但是如果通过J6连接，则需要进行电路板修改。默认情况下，EVE板上的USB到UART芯片控制接收线到BM64，并且不允许J6的UART引脚在通过USB供电时工作。如果你想通过USB来从USB设备上发送命令，你必须断开Q11。我已经能够使用BM62的评估板通过UART连接，但是我还没有能够在自己的原型板上连接UART（还没有确定为什么）。

    A couple of questions to try and help out, I'm using the similar BM62.

• Are you using the evaluation board or is this built into a custom board?
  
• If using the evaluation board, are you connecting through the USB port or the UART header (J6)?
  
• Are you using the supplied PC programs from Microchip to connect to BM64 UART?
  

As Geoff states, the baudrate, by default is 115200 for the BM64.  The three important pins are:

• MFB - high
  
• EAN - low
  
• P2_0 - high
  

If you are connecting through the u*** port of the eval board you should be able to see communication at 115200 buad, but if you are connecting through J6, you will need to make a board modification.  By default, the USB to UART chip on the eval board controls the receive line to the BM64 and does not allow the UART pins of J6 to operate when powering through USB.  If you want to power though USB and send commands from an external device via J6, you must disconnect Q11.
 
I have been able to use the evaluation board for the BM62 to connect through the UART, but I have not been able to connect though UART on my own prototype boards (yet to determine why).

谢谢你的回复。我没有使用评估板。我有BM64猪背上PCB有SENA BT模块。我有BM64编程到9600波特，因为这是我正在发送SENA BT模块。

    Thanks for the responses.   I am not using the evaluation board.    I have the BM64 piggy backed on the PCB that had the Sena BT module.    I have the BM64  programmed to 9600 baud since that is what I was sending Sena BT Module.
