Hello, I am trying to implement OTA firmware update using Secure DFU.
SDK - 12.2
Softdevice - s132
Board - PCA10040 (nRF52)
I followed instructions mentioned here
Issues:
-
Once the bootloader code has been uploaded, device advertises as DFUTARG.
-
Able to connect to the device.
-
When I select .zip packet or .bin + .dat package, the following changes can be seen: "Initialising", "DFU starting" followed by immediate "Disconnected".
-
This is common to both nRF Connect and nRF Toolbox.
-
The procedure works fine with test_bootloader and test_hrm example.
-
Also, I am not generating a bootloader settings file as I just want to work with default settings.
Am I missing something, that is not mentioned on the link provided above?
