DFU Service not found

[NigelJu]

I want to upgrade FW.

Android app has done. but only iOS encounter some problems.

First, I try to download nRF Toolbox on Github. result is DFU Service not found.

I trace code, I find ExperimentalButtonlessDfuUUID is not as same as my UUID, so I change DfuUUID, but still other error.

Then, I ask android  friend how to implement it, but he say just call library function without any edition.

Second, I try to download nRF Toolbox on AppStore. result is DFU Service not found, too.

Is zipFile with some limit between android and iOS?

Hi Nigel, 

which SDK version are you using to build your application on the nRF51822?

Could you try to add the DFU service from the SDK without modifying the UUID of the service and then see if that solves the issue?

Also could you use nRF Connect for iOS to connect to your device and add a screenshot of the discovered services ? Just want to check that the DFU service is added correctly.

Best regards
