DFU failure

[mregan11]

I'm using SDK 15 and soft device S132 6.0.  Using nrf Toolbox to update custom firmware, I'm running into a situation where the DFU update fails with an error code 4 when trying to rename to DfuTarg before resetting into the bootloader.  

What are some possible reasons why this failure could occur?  What is error code 4?

I'm using similar firmware in other instances and have not had this error occur, so I'm looking for reasons why this error could occur.

Thanks,

Matthew

Hello Mathew,

I don't think that the phone is trying to rename the device. Are you sure that the phone is not trying to find a device named DfuTarg?

 

Do you have another DK, so that you can try to do this using nRF Connect for Desktop?

 

Is there something special that you have done with the bootloader? Static address, Bootloader requires bonding? Have you changed anything in the Bootloader project?

 

Best regards,

Edvin
