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
I haven't tested the mac version. It should probably be the same way. Open the Bluetooth Low Energy application in nRF Connect. Connect to your device (buttonless_dfu). I'l just use the normal bootloader project for now.
After connected, press the DFU button. Please see the attached screenshot:
Then you just select the file which you want to upload, and press "Start DFU".
Since you are able to upload some DFU packets before, I assume you have got the basics up and running, but just in case it may be of any help, I'll attach a link to a blog post describing how to perform the DFU operation step by step.
