大家好。 原计发送广播信息一次后设置定时器参数再进入睡眠状态PM2，现在我通过uA表看到电流远不只文档上说的0.8uA。 通过调试最后发现居然执行BSP_Init();后睡眠模式就不好使了（睡眠代码放到这行前确实为0.8uA）。 BSP_Init(); //假如注释这句就能去到0.9uA左右。 //Init_SLEEP_TIMER_5s(); P1DIR = 0x03; while(1) PowerMode(2); 这里测试永远都是100uA左右，请问无线发射后怎么进入PM2模式？ 谢谢。

大家好，我想连接RN4020与我创建的Android应用程序，并使用一个具有许多特点的私人服务。我不想使用MLDP。最终目的是将RN4020与PIC连接。Android应用程序将使用SURR命令查询数据，RN4020将以特性来回答。我配置了如下模块：如果我启动旧的MLDP终端（关闭源）应用程序，它列出RN4020，但是如果我启动新的（开源），它不列出BT模块，并且如果我启动谷歌的蓝牙GATT应用程序。有人知道是否有一些与RN4020模块一起工作的开源应用程序？提前感谢 以上来自于百度翻译 以下为原文 Hi everyone, I'm trying to connect rn4020 with an android app created by me and use a private service with many characteristics. I don't want to use MLDP. The final purpose is to connect the rn4020 with a pic. The android app will ask for data with SUR command and the rn4020 will answer with the charcteristics. I'm configured the module as follow:SF,2 //factory resetPZ //clear private serviceSS,00000001 //Enable private serviceSR,20000000 //auto advertisePS,123456789012345678901234567890FF // create a service with this uuidPC,12345678901234567890123456789011,12,14 // create a charcteristic with this uuid, readable and notifyable and 20 bytes longR,1 If I launch the old MLDP terminal (close source) app it lists RN4020, but if I launch the new one (open source) it doesn't list the BT module and also If I launch the bluetooth GATT app made by Google. Do anyone know if there is some opensource app that works with rn4020 module?Thank you in advance

在这里：http://MicroChIPDeavic.com／FAQ:96:你会发现一个非常简短的微芯片开发者帮助文章：“我如何把RN4020模块放在观察者的角色中去接收广告数据包？”本文的主要内容是：“一个模块作为一个外围设备，另一个模块作为中心。在中心发出命令“j，1”，后面跟着命令“f”。在外围设备上，发出“N”命令，后面跟着要做广告的数据。发布外围设备的“A”命令开始广告。“我已经成功和失败了这个过程，可能是基于外围节点的‘n’和‘a’命令的相对定时，以及中心节点上的‘j，1’和‘f’命令。可能还有其他问题。两个无线节点的配对是最异步的过程。很明显，不能将时间强加给用户。它必须工作，不管这两个节点是如何相互呈现的。当我成功时，我看到的广播消息是：我希望：：1001EC01CF7B6，0，35，BRCST：0201040CFF46E616C5265656C4C43.当不成功时，我看到每次都是相同的伪消息：：00，-35注意到，两个接收到的消息具有相同的（正确的）MAC地址。如果我不发出“A”命令，则“F”命令什么也得不到。相同的软件结构是成功和失败的基础。看来，如果“A”命令在“F”命令前面一秒钟左右，一切都有效。有没有实现Microchip开发者帮助文章的最佳实践方法？我想感谢RISC和MyZigBee在帮助我达到这一目标方面的帮助，特别是对广告结构的广播消息管理器特定数据字段的解码。如果你们中的任何一个可以评论和评论这个问题，我将非常感激。 以上来自于百度翻译 以下为原文 Go here: http://microchipdeveloper.com/faq:96 There you will find a very short Microchip Developer Help article entitled: "How do I put the RN4020 module into an Observer role to receive advertising data packet?" The text of this article is: "Set up one module as a peripheral and the other as a central. Issue the command ‘J,1’ on the Central, followed by the command ‘F’ . On the Peripheral, issue the ‘N’ command followed by the data you want to advertise. Issue the ‘A’ command on the peripheral to begin advertising." I have had success and failure with this procedure, possibly based on the relative timing of the 'N' and 'A' commands on the peripheral node and the 'J,1' and 'F' commands on the central node. There may be other issues. The pairing of two wireless nodes is about the most asynchronous process there is. Clearly one cannot impose timing on the user. It just has to work, no matter how the two nodes present to each other.. When successful, I see the broadcast message I expect: 001EC01CF7B6,0,-35,Brcst:0201040CFF446E616C526565664C4C43 When not successful I see a bogus message that is the same every time: 001EC01CF7B6,0,,00035B0358E607DD021A08123A000300,-35 Note that both received messages have the same (and correct) MAC address. If i do NOT issue the 'A' command, the 'F' command receives nothing. The same software structure underlies both successes and failures. It does seem that if the 'A' command precedes the 'F' command by a second or so, everything works. Is there a best practices method of implementing the Microchip Developer Help article? I would like to acknowledge both RISC and myZigbee for help in getting me this far, especially the decoding of the broadcast message MANUFACTURER SPECIFIC DATA field of the AD Structures. If either of you could review and comment on this issue I would greatly appreciate it.
