nrf52840 dongle connectivity doesn't work

[Banban]

Hi,

I downloaded nRF5_SDK_15.3.0_59ac345.

The first time,

Uploaded "..\examples\connectivity\ble_connectivity\hex ble_connectivity_s140_usb_hci_pca10059.hex" by nRF Connect Programmer.

But the dongle didn't work, and nRF Connect Programmer displayed:

The second time,

I opened "..examples\connectivity\ble_connectivity\pca10059\ser_s140_usb_hci\ses ble_connectivity_s140_usb_hci_pca10059.emProject" with SEGGER Embedded Studio and built this project. Uploaded "..\examples\connectivity\ble_connectivity\pca10059\ser_s140_usb_hci\ses\Output\Release\Exe ble_connectivity_s140_usb_hci_pca10059.hex" and "..\components\softdevice\s140\hex s140_nrf52_6.1.1_softdevice.hex" by nRF Connect Programmer. 

nRF Connect Programmer displayed the same errors.

My question is "How to compile and use connectivity for nRF52840 Dongle?"

Best regards

Hi

The reason you see that the Dongle is unable to reopen after flashing an application onto it is that it no longer is in bootloader mode. I just tested this myself with the SDK v17.0.0 connectivity example (\...\nRF5_SDK_17.0.0_9d13099\examples\connectivity\ble_connectivity\hex). After the device finished the DFU procedure and failed to reopen the device I got a pop-up saying the nRF52 Connectivity device was available in my "Bluetooth & other devices" page in Windows settings.

For more explanation regarding the Dongle and its bootloader, please check out our Dongle Programming tutorial, which goes into detail on this.

Best regards,

Simon
