除了信标之外的任何东西都需要1.33版本的RN4020？

我猜你正在谈论蓝牙模块。但是哪一个呢？？？？

    I will Guess your are talking about a Bluetooth Module.  But which one???

嗨，RN4020V1.33 FW有以下的发布说明：http://WW1.Microchip .com /下载/ En/DeViceOC/RN4020%20固件%201.3BEC %20版本%20Notes May2016PDFIT增加了一些特性

我在MLDP模式中使用RN4020。我看不到1.33个版本和旧版本的区别。



      以下为原文

    I'm using RN4020 in MLDP mode.  I see no difference between 1.33 and older versions.

谢谢，这是我的经验，加上我有一些麻烦（现在记不起来）1.33版本。而且，DeXo（DigiKi& & Mouser）有很多1.23个，但还不到1.33个。



      以下为原文

    Thanks, that's been my experience, plus I had some trouble (can't remember now) with the 1.33 version.
 
Also, Distro (Digikey & Mouser) have lots of the 1.23, but not much 1.33 yet.
 

你可以下载UpDATEr4020YDUFIUTITYYYFF110-133，从理论上讲，你会允许使用流控制的UART电缆升级固件到1.33（RTS/CTS）吗？老实说，我尝试过，甚至无法与模块进行流量控制。E固件嵌入其中，所以无法提取。RN4020升级的另一种方法是通过UART电缆（无流量控制）、终端（TelAtTM等）和升级文件。这对我起了作用。显然流量控制是必须的，但是我把波特率设置为9600，我成功了很多次。您用“~”（在手册中描述）开始升级，然后将文件发送为“二进制文件”（重要），也可以使用成对的设备来升级OTA（在空中）。风险更大，好像文件被破坏了，再也没有办法了…无论如何升级都是有风险的操作，我已经用几个模块结束了BLICKED。似乎不是一个办法，你必须假设你会砖块，他们还会出售更多的。据我所记得的升级文件不在网站上，所以你可能会要求他们。我想我是在别的地方找到的，出乎意料（或不是）。



      以下为原文

    You can download the updater  RN4020_DFU_Utility_fw110-133BEC
that, in theory, will you allow upgrading firmware to 1.33 using a UART cable with flow control (RTS/ CTS)
To be honest, I tried and just wasn't even able to communicate with the module with flow control.
Unfortunately that application has the firmware embedded on it so you can't extract it.
 
Another way of upgrading the RN4020 is by a UART cable (no flow control), a terminal (TeraTerm, etc) and the upgrade file. This worked for me. Apparently flow control is a must, but I set the baud rate to 9600 and I succeeded a number of times. You start the upgrading with '~' (described in the manual) then send the file with 'Send file' as 'binary' (important).
 
It's also possible to used a paired device to upgrade OTA (over the air). More risky as if the file gets corrupted there is no way back... Upgrading is anyways a risky operation, I already ended with a few modules bricked. Doesn't seem to be a way around, you have to assume you will brick some and they will sell some more as well.
 
As far as I remember the upgrade files are not in the website, so you might ask for them. I think I found them somewhere else, surprisingly (or not).
