About the device_firmware_updates project

[Angela]

Hi,

I'm knowing the device_firmware_updates project in SDK and I want to know whether I need to program the softdevice when I do the device firmware updates over UART?

I have read the help document of nRFgo Studio and do as the serial bootloader say,but I can update the firmware over the UART.Could I just use the nRFgo Studio to do it?

Must I do it by the command line?If it does,could you tell me how to do it?I cann't understand well by reading the readme.txt in hci_dfu_send_hex folder.

thanks

Is there anyone master that can answer my question?Or give me some advice?It seems that the DFU cann't be done by UART

Hi Hung Bui,

Could you tell me how to do the modification if I don't want to have the softdevice?Because we have some product havn't use the softdevice.Thanks.

I also try to use use the DFU via UAR(have softdevice):

• Flash the softdevice
• Flash the bootloader using nRFGo Studio
• Fflow control is used and use the default baud rate,

Then I can see the LED1 is lighted.I put the *.hex document at C:\NewFirmware and load it via nRFgo Studio.But it cann't update the firmware and stay at the status all the time(as attached).

Besides,I also use the CMD to do it:hci_dfu_send_hex.exe -f C:\NewFirmware\ble_app_hrs.hex -p COM 1 -fc -b 38400. But I still cann't update the firmware.

Could you give me some advice?Thanks.

Look forward to your reply.Thanks.
