嗨,我正在制作使用RN870的定制板。昨天我可以通过UART访问RN48 70,但现在不行。这个模块似乎处于待机状态。(P1Y0:STATES2=低,P1Y1: STATES1=高)我不知道是什么原因,所以我想做“工厂复位”,但我找不到该程序的文件。如果有人知道怎么做,你能让我吗?或者,请告诉我如何退出待机状态。

(P1_0:Status2=Low, P1_1:Status1=High) I don't know what is cause, so I want to do 'Factory Reset'. But I could not find out document of that procedure. If anybody knows how to do that, could you let me? Or, please let me know how to exit from standby state. Best regards, |

工厂重置是命令“SF,1”。但是如果你的模块失去了MAC地址,这将无济于事。请参阅本主题:HTTP://www. McCHIP.COM/FUMMS/M954 916.ASPX
以上来自于百度翻译 以下为原文 Factory reset is command "SF,1". But if your module has lost its MAC address, this will not help. See this topic: http://www.microchip.com/forums/m954916.aspx |

谢谢你的回复。我联系了当地销售,他们现在支持我。模块是启动,但显示%unNoNeNoice %,所以我放弃修理,并将该模块更换为新的。
以上来自于百度翻译 以下为原文 Thank you for your reply. I was contacted local sales and they support me now. Module is boot but that display %UnknownDevice%, so I was give up to repair and replaced that module to new one. |

在之前的命令完全由模块响应之前,我已经通过发送命令来擦除其中的至少一个。在发送另一个命令之前等待完整的响应(包括对每个命令都像l& Cr & gt;lt & lfgt)的完整响应是非常关键的。
以上来自于百度翻译 以下为原文 I've bricked at least one of these by sending commands before the previous commands were completely responded to by the module. It is critical to wait for the complete response (including delimiters like |

谢谢你的回复和做测试。你能告诉我你在测试中执行了什么命令吗?如果你还记得的话。我从本地的销售中听说过,如果关闭电源,模块在执行命令和NVM(非易失性存储器)写入之间的时候,模块就不能工作。(S.PC命令)最好的问候,
以上来自于百度翻译 以下为原文 Thank you for your reply and to do test. Could you tell me know what command did you execute in testing, if you remember. I heard from my local sales, sometime the module get to not work if shut down a power the module between executing command accompany with NVM(Non-Volatile Memory) write. (ex. SN, PC command) Best regards, |

我不使用PC,但我确实使用SN;这是一个很好的点在发送命令时,它的写入NVM。我也认为它不喜欢在完成引导并发送%ReGue%%之前接收命令。最安全的做法是等待每一个命令的每一个回应。
以上来自于百度翻译 以下为原文 I don't use PC, but I do use SN; that's a good point about sending commands while it's writing NVM. I also think it doesn't like receiving commands before it has finished booting up and sent %REBOOT%. The safest thing to do is wait for every response to every command. |

感谢您的回复。我将仔细编程,避免在收到响应之前执行命令。
以上来自于百度翻译 以下为原文 Thank you for your reply. I will programming carefully that avoid execute commands before receive a response. |

启用命令“SR,8000”的流量控制和处理信号(RTS/CTS)?-有人在实际操作中尝试过吗?
以上来自于百度翻译 以下为原文 Enable flow control by command "SR,8000" and process the signals (RTS/CTS) ? --> Has anyone tried this in real operation ? |

是的,我在我的应用程序中使用流控制。只需在PIC中设置,然后在模块中打开它,它似乎起作用。
以上来自于百度翻译 以下为原文 Yes, I'm using flow control in my application. Just set it up in the PIC, then turn it on in the module and it seems to work. |
