使用DFU-OTA将RN4020固件更新至1.33 如何设置发件人收件人？

您好，A）我有一个RN4020演示板（ReV1.33），它通过USB与PC连接，在那里可以与它通信，使用终端PROG。B）我有一个自己的应用程序，带有RN4020（Rev 1.23）和一些PIC控制器，我可以根据需要来安装。我想更新B的固件。4020至1.33，使用DFU-OTA。这意味着A将连接到B，并发送固件二进制。我已经有二进制文件1.33。有人可以帮助双方的必要设置，让他们连接，并发送固件文件，请？我搜索了很多，我发现的是接收器：+//Eng/ONSF，2 / /执行完整的工厂ReSETSR，10008000 / /支持MLDP，启用OTA（默认模式下启用外设）R，1 / /重新引导应用设置/ /等待“CMD”A//开始广告，但如何设置发送者RN4020？我发现，我需要命令E连接，对于接收器~，2进入DFU模式？有人能帮忙吗？如何正确设置发送者和收件人？这会有很大的帮助（我想不仅对我来说），最好的问候，Juergen

    Hello,

A) I have a RN4020 Demo-Board (rev1.33) which is connected through u*** with a PC,
and there I can communicate with it, using a Terminal prog.

B) I have an own application with a RN4020 (rev 1.23) with some pic controller,
which, I can setup as necessary.

I want to update the firmware of the B) RN4020 to 1.33,
using DFU-OTA. This means A) will connect to B) and send the firmware binary.
I have the binary file 1.33 already.
Can someone help with the necessary setup for both sides,
to get them connected, and to send the firmware file, please?

I googled a lot, what I found out is for the receiver:
+                // echo on
SF,2             // perform complete factory reset
SR,10008000     // support MLDP, enable OTA (peripheral mode is enabled by default)
R,1             // reboot to apply settings
                // wait for "CMD"
A               // start advertising

But how to setup the sender RN4020?
I found, I would need command E to connect,
and for the receiver
~,2
to enter DFU mode?
Could someone please help, how to setup the sender and reciver exactly?
That would help a lot (and I guess not only for me).
Best regards, Juergen
