Trouble with buttonless DFU when using NRF52832 and nrf toolbox

[Gz]

Hi, My SDK version is 13.0 and my problem is when I run the examples\ble_peripheral\experimental_ble_app_buttonless_dfu project the 52DK seems ok but when I use the DFU in nRF Toolbox App, I have connected the 52DK and about uploading files, the error informations are "DFU CHARACTERISTIC NOT FOUND ".

And I notice there need a command to trigger DFU on 52DK, and I haven't found the way how to send the command in the App.

So how to use buttonless_dfu example to update the firmware?

Hi Gz, You need to test the bootloader first before you test the buttonless example. I suggest you to have a look at the documentation of the bootloader. You can follow my guide here. Buttonless guide is at the end.
