Problem in DFU implementation for nrf52 thingy

[suvarna_kadam]

Hi

I am using nrf52 thingy hardware version 1.0.1

I want to use OTA for the same module with customize application.

Till the time  I am able to transfer firmware file over DFU but the problem is with ble settings. After the DFU device fails to change advertising name and other ble settings like advertising timeout and connection timeout. Other peripheral changes are successfully updated but this fails the ble settings.

I am referring the following link for the DFU files

1. https://devzone.nordicsemi.com/nordic/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader

2. https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrfutil%2FUG%2Fnrfutil%2Fnrfutil_pkg.html

3. https://nordicsemiconductor.github.io/Nordic-Thingy52-FW/documentation/dfu_generating.html

For zip file I am using following command

nrfutil pkg generate --hw-version 52 --application-version 0 --application app_thingy_s132.hex --sd-req 0x98 --key-file private-key.pem app_dfu_package.zip

Can anyone help me for this help?

Thank you.

Hi.

Have you checked that your new firmware actually works alone?

If your device somehow "fails to change ..." it sounds like it does not boot correctly.

Hi AndreasF

I test device with edited firmware so it is but there issue is I have to flash softdevice every time along with application firmware. Changes did in  file thingy_config.h is not getting updated without uploading softdevice.
