SDK 13.0 couldn't do DFU using UART when disable flow control

[Alice]

Hi,

I'm using nRF52832 and nRF52840 to work with MCU, then we should do the firmware update by the uart. I have compiled the bootloader_secure_serial project in the SDK 13.0 and then program it to the DK board, I run the command in the command line:

nrfutil dfu serial -pkg Blue5_test.zip -p COM5 -fc 1 -b 115200

It's OK. There is no flow control on my board, so I disable it in the serial_dfu_transport_init() function:

uart_config.hwfc               = NRF_UART_HWFC_DISABLED;

Then run the command:

nrfutil dfu serial -pkg Blue5_test.zip -p COM5 -fc 0 -b 115200

But it couldn't update the firmware and get the error as follow:

Bjørn Spockeli，

Could I see the code for the nrfutil on the command line about how to implent the DFU?

Our ble module is working with the WIFI module via the UART interface. So we would use the UART to do DFU and the zip package would be placed at the server,that is to say, put the zip package in the clound then send it to the wifi module through WIFI and then do DFU through UART.
