We want to Implement Nordic DFU function by ourself,but the DFU library and soruce code is not available to us.

So we need to get the Nordic DFU OTA documentation which describe the detailed upgrade process, where can find it?

Hi bh.niu, 

 

What do you mean by "DFU library and soruce code is not available to us." which library are you talking about ? Is it the mobile phone app library  or the firmware library ?

The documentation describing DFU protocol, you can have a look here.

We will make a “WeChat Mini Program ” to upgrade ble device.

“WeChat Mini Program ” is a program like mobile phone app，which is very popular in China.“WeChat Mini Program ” can not use mobile phone app library or mobile phone app source code directly.

We want to know how to pack commands and how to use commands.
