嗨,我正在使用RN467 7双模式蓝牙模块,由于某种原因,我把波特率改为9600,它工作了一段时间,后来它停止在UART中响应,我把CTS引脚拉低,我尝试了工厂复位命令仍然不工作。E到9600,配对没有发生,但是UART侧可以看到发送的数据,配对不是发生在最新的Android手机上(更高的KITKAT(Android版本4.4.2)),Android KITKAT Mobile是配对的,并且我在两个方面发送数据,问题是更高版本(注:我有E)在移动时,我尝试过在这个模块中的工厂重置,在移动侧当我尝试配对它随机显示2个错误消息1)不能与DualySPP 2通信)不能与DualySPP(模块名)配对因为不正确的PIN或密钥,模块是双M的。ODE和认证模式是“WorkWork”。是否有任何程序来改变我丢失的UART波特率,我刚刚发出命令SU,96 & lt;Cr & Gt;请尽快帮助我。谢谢,Sunil Kumar。
以上来自于百度翻译 以下为原文 Hi, Iam working with RN4677 dual mode bluetooth module, for some reason i changed the baudrate to 9600, it worked for some time, later it stopped responding in uart, i have pulled CTS pin to low, i tried the factory reset command still not working. In another module(RN4677) after changing the baudrate to 9600, pairing is not happening but uart side i can see the transmitted data, pairing is not happening for latest android mobiles(higher then kitkat(Android version 4.4.2)), android kitkat mobile is pairing and i transmit the data on both side, the problem is for higher versions (note: i have enabled the GPS in mobile while trying), i have tried factory reset in this module too, in mobile side when i try to pair it randomly shows 2 error messages 1) cannot communicate with Dual_SPP 2) Couldn't pair with Dual_SPP(module name) because of an incorrect PIN or passkey, the module is in dual mode and authentication mode is 'Just Works'. Is there any procedure to change uart baudrate which iam missing, i have just sent the command SU,96 Thank you, Sunil Kumar |

我知道这是一个旧的帖子,但是在RN467 7固件中似乎有一个bug影响低波特率。他们已经修复了它,但出于某些原因,似乎不想释放更新的固件。我相信RN467 7实际上是过时的,他们推荐使用RN467 8而不是在英国似乎还没有广泛使用。
以上来自于百度翻译 以下为原文 I know this is an old post, but there appears to be a bug in the RN4677 firmware which affects low baud rates. They have fixed it but for some reason don't appear to want to release the updated firmware. I believe the RN4677 is in effect obsolete and they are recommending using the RN4678 instead - which doesn't appear to be widely available in the UK yet.... |

该模块有一个V1.11固件更新。我听说还有一个更新。我听说他们也搬到了RN467。但77人仍然可用。
以上来自于百度翻译 以下为原文 There is a v1.11 firmware update for that module. I am told there will be another update. And I heard they are moving to the rn4677 too. But the 77 will still be available . |

难道你不喜欢微芯片支持系统吗?我有一个开放的票RN467 7臭虫,他们还没有告诉我关于新的固件…我正在考虑移动到RN467 8,但接口太复杂,需要太多的处理器引脚管理唤醒,复位等。我想知道他们是否正在计划一个BT4经典的唯一模块,以取代RN。42?它的牙齿越来越长,但RN46X系列是支持经典模式的唯一选择。
以上来自于百度翻译 以下为原文 Don't you just love the Microchip support system? I've got an open ticket on RN4677 bugs and they've not told me about the new firmware... I was considering moving to the RN4678 but the interface is too complicated and needs too many processor pins to manage wakeup, reset etc. I wonder if they are planning a BT4 classic-only module to replace the RN42? It's getting long in the tooth but the RN467x range are the only options that support classic mode. |
