nRF52840 dongle issue

[Rajneesh]

Hello Nordic team

I am working on "ble_app_uart_pca10056_s140" SDK V-15.2. IDE: Segger Embedded Studio.

After compiling above project I am trying to download two files "softdevice" and "application" via nRFConnect PC application but after successfully download dongle doesn't working.

Then I download pre-compiled "ble_app_uart_pca10056_s140.hex" in dongle via nRFConnect PC application and dongle working and advertising.

So, my question is do we have to change anything in setting/configuration for nRF52840 dongle or do we need to merge softdevice and application file?

If need any settings/configuration please let me know which one?

If need to merge two files please provide me steps or commands. Or any link.

Any help will be appreciated.

Regards

Raj

Hi Raj.

Have you looked at the Getting Started Guide and Programming Guide for the nRF52840 Dongle?

To program the Dongle, it must be in bootloader mode.

If you want to program the ble_app_uart_pca10056_s140.hex:

1.Put it in bootloader mode as the programming guide shows.

2. Open nRF Connect Programmer.

3. Add the application .hex file and the S140 SoftDevice hex file:

ble_app_uart_pca10056_s140.hex

s140_nrf52_6.1.0_softdevice.hex

4. If LD2 on the Dongle still pulses red, simply take the Dongle in and out of the USB port.

You should then be able to see the Nordic_UART application in nRF Connect on your mobile phone advertising.

You do not need to merge any files.
