Transfter data from Linux PC to nRF52840 dongle over USB

[jitendra_cf]

Hi,

I have just purchased a nRF52840 usb dongle (https://www.mouser.in/ProductDetail/Nordic-Semiconductor/nRF52840-Dongle?qs=gTYE2QTfZfTbdrOaMHWEZg==).

I would like to transfer data from linux PC to nRF52840 dongle over USB and it can be read through any custom characterstic.

Is it possible to achieve this ?

All suggestions are appreciated.

Thanks and Regards,

Jitendra

Hi Jitendra.

Sorry for the late reply.

You can take a look at the Dongle Programming Tutorial, and instead of using the Blinky example, you can use the UART example.

Hi Andreas,

I have tried using UART example for nRF52840 dongle. Its USB works as nRF SDFU COM when dongle is in bootloader mode (Please find attached screenshot). When it exits from bootloader mode, there's no com port. So How can we test UART example ?

Any idea? 

Thanks & Regards,

Jitendra

Hi Jitendra.

Have you done the following:

1. Open the folder nRF5_SDK_15.2.0_9412b96\examples\ble_peripheral\ble_app_uart

2. Copy the folder pca10056 and rename it pca10059

3. Looked at Adapt a BLE example (with SoftDevice) and program it using nRF Connect Programmer in the Dongle Programming Tutorial, that is changed BOARD_PCA10056 to BOARD_PCA10059 and compiled the project

4. Added the Application hex file and the SoftDevice hex file to the Programmer Application and programmed the device?

Best regards,

Andreas
