Mesh DFU Failed to establish connection

[Jeffe]

Hi, recently I am been consistently getting the same issue as this post, despite having successful performed the Mesh DFU in the past and with the example code:  NRF MESH SDK5 DFU issue "Failed to upgrade target. Error is: Failed to establish connection" 

I suspect my issue might be the same as the person in this post, however, the person did not give much details.

Thanks in advance

Hello,

What kind of error do you get? And what did you try to do? You say that you succeeded running Mesh DFU in the past with the example code. What are you doing now? Are you still running the same example code? Did you change SDK version? Did you try to integrate DFU into a custom project? Some more details would be nice.

Best regards,

Edvin

apologies for that. I am currently running nrf5 SDK for Mesh 5.0.0. First i tried it on my custom project, where in the past it worked but recently got the issue as described in the opening post. At first I thought it might've been something in my code so I spent a long time trying to figure out the issue but to not avail. I decided to use then just go back to using example code only as a sanity check but the issue still happens. 

I suspect it also might be related to my environment, I always ran the Mesh DFU using a Ubuntu Laptop, both in the past and in the present. However, just 2 days ago I tried running the Mesh DFU with using example code on a Windows PC and it seemed to work. But when I tried today with the same example code again it failed with the same error as described in the opening post. 

I'm currently really puzzled, I will try to do more tests, and double check my procedure in the meatime
