nRFgo Studio cann't update the firmware via UART

[Alice]

Hi,

I use the UART to do the device firmware update and have used the dfu_dual_bank_hcl to compile.I use the nRFgo Studio V1.16 to program the s110_nrf51822_5.2.1_softdevice.hex and bootloader.Then I can see the LED1 is lighted.I put the *.hex document at C:\NewFirmware and load it via nRFgo Studio,use the default baud rate and enable flow control.but it cann't update the firmware and stay at the status(as attached).

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.

Hi Alice,

Have you verified you connected all four pin for UART on the nRF6310 properly ? You can refer to the attached image for the setup.

Your python error seems quite strange. On which machine and OS did you run the test ? We have only tested on Windows 7. Could you try on other machine ? You can try to uninstall Python for testing. The .exe doesn't require python to be installed.

Note that when the HCI bootloader running, LED2 should be lighted, not LED1.

I will try to make an example of using bootloader without softdevice and will havea an update when it is ready.
