Update SDK and SofDevice 110 to SoftDevice 130 by DFU

[Astalos]

Hi

I have firmware uing SDK 7.1 and SoftDevice 110. There is prepared bootloader for DFU, and update by very old nrfToolbox app works fine. But now I want to update this firmware to SoftDevice 130 and SDK 11.0 (also bootloader). How can I accomplish this? When I try to update old firmware by newest nrfToolbox app, it says "DFU not supported". Should I prepare images in some special way?

@Astalos: When you flashed the S110, have you selected "Enable Softdevice protection" when you flash the softdevice ? If you don't then it's possible to update the softdevice to S130. Please be aware that S130 v2.0 is only compatible with nRF51 chip version 3.

The nRFToolbox app should still work with bootloader from SDK v7.1. Have you made sure you switched to the bootloader and the application does a service discovery (meaning service changed characteristic should be enabled) when it connect to the bootloader ?

You can also try to use nRFConnect to test if it works.

I didn't enable Softdevice protection. But will it be possible to make such update with .zip package with bin, manifest.json etc. created by nrfutil? Or have I to make old-style package?

It doesn't matter, the .zip or "old style package" is only for the DFU app, when sending data over the air, they are the same.

@Hung Bui Hi, If I use 3in1 hex file to program my 51822 and select "Lock entire chip from readback". Can I update softdevice from S110 to S130 by DFU?

It's still possible. As long as you don't set the check box to "Enable Softdevice protection" when you flash the softdevice.
