DFU function of nRF Connect and nRF Toolbox apps

[JerryZW]

Hi, i have application with buttonless DFU and boot loader. I am able to upload distribute zip package to the board via nRF Connect and nRF Toolbox apps on Android. But the DFU functions of these two APPs does not work on iOS. 

(1) For nRF Connect, the dfu button does not show up when the Phone got connected with "DfuTarg". 

(2) For nRF Toolbox, the device firmware update got stuck at "connecting". 

My IOS version is 10.0.3. Is there any way to solve the problem? Thanks.

Hi!

Maybe you could provide me with some additional information?

Are you using the nRF52 DK? Also, which version of the SDK are you working with?

Are you using the latest version of nRF Connect and nRF Toolbox?
If not, which version are you using?

Cheers,
Joakim.

Hi Joakim,

Thank you for your reply.

(1) Yes, I am using nRF52 DK

(2) I don't know how to check the SDK version, but the softdevice version is 4.0.3. Is there anyplace I can check the SDK version in the SDK folder?

(3) Both apps are newest version, nRF toolbox is 4.4.4, nRF Connect is 1.8.5. My IOS version is 10.0.3.

Thank you so much for your assistance.

Thank you for the update.

I'll see if I'm able to reproduce this, so we can find out what the issue might be.

2) Yes, you can open your SDK folder, go to documentation and open the release_notes.txt. The SDK version should be at the very top.

Cheers.

Hi.

Maybe you could take a look at this thread and the answer from Bjørn, and see if that could be related to your issue.
