Hi David,
I've tested this with SDK 16.0.0. I didn't make any modifications to the bootloader except for changing the public key. To test it, unzip the attached zip and program the softdevice and bootlaoder in \dfu_test\bl+sd. Then try to do DFU with the included app_dfu.zip package.
Note: there seems to be a bug in the latest pre-release of nrfutil. Please make sure you're using nrfutil v.5.2.0. https://devzone.nordicsemi.com/f/nordic-q-a/54202/error-of-invalid_object-when-using-nrf-connect-desktop-after-generating-dfu-zip-file-with-new-keys
Hi Vidar,
Do you have the document for bootloader?
How it initializes and sends data package to from the APPs to bootloader?
I mean the shakehand of the communication between the Apps & bootloader.
Thanks,
David
Hi Vidar,
I also see this issue. I sends data over the UART to nRF52810 CPU. Sometimes, it causes issue below. I seems the UART registers are messing up?

David
Hi David,
Please create a new thread for the UART question and try to include more information about the problem. Preferably the full project and instructions on how to replicate it. It's strange that the debugger reads all the UART0 registers as 0xAAA..
Hi Vidar,
OK, can you answer case#1 vs. case#2 above?
Thanks,
David
Hi Vidar,
Even I sends 1 byte every 5s. it still waits until reach the PDU length 185 before it sends out.
void sendaByteData()
{
USART_SendData(USART1,0xEF);
}
Can you help to look into this?
Regards,
David
