ble disconnection in dfu mode

[prateek]

Hi All,

i am working on SDK-14.2, i am facing issue with ble disconnection in dfu mode.

by using nrf-Connect in mobile i am upgrading the firmware, but it lost connection when dfu reaches 15-20%. after that it re-connect with device and still in dfu mode.

when i re-Select  the zip file. it start again where dfu stops.

there is one more problem with the speed, it takes around 5-7 min to complete the dfu process.

please see the log in the snapshot.

please help me to resolved the issue.

Thanks,

Prateek

Hi Prateek.

Which examples are you using? Are you using any of the DFU bootloader examples, and which one?

Hi Andreas,

I am using my custom code with the help of DFU Bootloader Example.

In Previous, i am using sdk-11 which works fine in dfu and i am not getting any issue with DFU, while currently i am upgrading my sdk to 14.2 in which i am getting this issue.

Thanks,

Prateek

Hi Prateek.

Could you please upload your project so I can have a look at it?

Hi Andreas,

i can't upload complete project to thread. you can ask me the section you want to look.

Thanks,

Hi Prateek.

I really need more information in order to be able to help you. Can you post any debug output? Output during the dfu? Are you using Watchdog? Can you please add your main.c and sdk_config.h?

- Andreas

Hi Andreas,

I am uploading main.c and sdk_config.h, i am not using watchdog in this.

i am using

Moto G5S plus - Android 8.1.0 - finding multiple time disconnection issue - 0x85,0x08 error code

Nexus 6P - Android 8.1.0 - Single time disconnection issue - 0x85,0x08 error code

Hi.

I'm not able to reproduce the error with the main.c file and sdk_config.h file you supplied. Could you please upload the project in a .zip file or do a debug in Segger Embedded Studio as I suggested previous?

Hi Andreas,

My hole application is based on ARMGCC and i am in last stage of the project, in that i am not able to use any other tools for the development. as i debug this in nrf Connect, i am getting  error code ( 0x85, 0x08, 0x16).

please help me to resolved the error, if you have nos of solution, provide me i am trying everything asap.

thanks.

[AndreasF]

Hi Prateek.

As I previously said, based on the information you have provided I cannot draw any conclusion to what may cause your problem. To understand the events leading up to this issue the project must be debugged, either by you or me. The error codes you provide gives little insight to where or what has gone wrong in the code.

Please debug the project or upload it in a .zip file so that I can debug it.
