nRF52840 DFU problem

[Yinbun Ye]

Hi，

    I can dfu successed by using PC's nRF Connect with 2xDKs, but can't dfu by using Android's nRF Connect. For mobile's dfu, just enter 'DfuTarg' and auto conn, but could not see any data in trasmit in the dfu's uuid. And after a while, 'DfuTarg' disconn and ota failed and I don't know why

Did you click on the DFU icon in the upper right corner, and then uploaded the DFU zip file?

Enter the 'DFUTarg', click the dfu again,will stuck on 'initializing' screen.And I can dfu successed by using IOS's nRF Connect.

What Android phone brand and model are you using ?

What SDK version are you using ?

Do you see the same issue using the DFU function in nRF-Toolbox ?

[Yinbun Ye]

SDK15.3
I could dfu by One Plus 7 or IOS 12.2.
It should be caused by the phone is too old and the CPU is MTK.
thx a lot
