nRF Connect APP (Android) can't use BLE DFU after update to version 4.29.0

[Wayne_Chang]

Hi all,

last week i used nrf connect app (v4.28.1) to update firmware

after i pressed DFU button and selected binary file, then it will jump a window to choose like below

everything goes well

After I update app to version v4.29.0

I do the same thing, but the step after I select the binary file disappear

it doesn't show any window like the picture i show, and doesn't do any update step

I want to know is there any setting that I have to change after update the APP ?

Hi, 

I cannot reproduce it with the nRF Connect app v4.29.0 and zephyr/samples/subsys/mgmt/mcumgr/smp_svr. 

Please ensure to upload the package with modification.

Hi Amanda,

I did the same experiment as you say

I build the sample zephyr/samples/subsys/mgmt/mcumgr/smp_svr. (NCS 2.7.0) on nrf52840-dk

 

it still can't work on nRF Connect app v4.29.0 with samsung s23 ultra (Android14)

so I take another phone which has nRF Connect app v4.28.1 on samsung s10+ (Android 12),

and it works !!!!!

so I think the problem maybe is APP on different Android version ?

I don't think so. I tested on Pixel 6A (Android 14) without issues.

Hi Amanda,

I also borrowed a pixel 8 pro from my coworker
it also can't work
nRF Connect app v4.29.0 with Android 15
you can see the video i update:

and I also upload the video with previous two samsung phone
1. s23 ultra, v4.29.0, Android 14 (not working)

2. s10+, v4.28.1, Android 12 (working)

I judge success based on whether a window pops up after I choice a app_update.bin

Hi, 

Do you use the same file app_update.bin to test with these phones? I suspect not. 

I can reproduce the issue if uploading a different application without the same memory partitions.

I would suggest uploading the file build with the same pm_static.yml. You can duplicate build/partitions.yml, rename it to pm_static.yml, and place it under the application. Then regenerate the image with the pm_static.yml to upload.

I use the same binary file
To make sure that, i do it again with smp_svr on dk and regenerate binary file with only add some log printk for BLE OTA
and it still can't work

Today my s10+ update nRF Connect app to v4.29.0 by itself
and it can't work either...

Is there any previous version APK that i can download ?
