Good day to all
I am trying to change the Application on a device with an nRF52832 chip with an existing firmware. To do this, I use nRF Connect for Mobile 4.25.3. From the nRF5 SDK 17.1.0 examples/ble_peripheral/ble_app_beacon, I used ble_app_beacon_pca10040_s 132.hex and created it through nrfutil 5.2.0.a zip file of the firmware with the key I generated.
When I try to update the firmware via DFU, I get the following errors:
E 23:02:42.318 [DFU] Remote DFU error: INVALID OBJECT

What am I doing wrong? Can you tell me how to update the firmware?
