Running examples on nrf52840 dongle

[Obakeng]

Hi,

I tried to run the pca10056 ble_app_uart on a nrf52840 dongle (pca10059) after modifying the example as suggested here on the devzone. I had to define the rx,tx,ctx and rts pins since these are not defined in the board header file for the dongle. However, after these changes and compiling using the Makefile under the armgcc folder and programming the resulting hex and the softdevice using nrfconnect, it did not work.

Could you please advise as to further changes that are needed to get the example to work as well as how to get general pca10056 examples to work on pca10059 (nrf52 dongle). Please note that I do not have the DK and cannot get hold of one in the time period I need to get this to work.

Note: I have got the examples meant for pca10059 to work without modifications.

Thanks,

OB

Can you elaborate on this statement:

programming the resulting hex and the softdevice using nrfconnect, it did not work.

Does it not work to program the application? Is the application not advertising? Is the data not coming over UART?

Which pins did you configure for UART peripheral? How did you connect UART to PC? Note that there is no Segger Debugger chip on the Dongle, meaning that there is no "automatic" UART to USB interface. If you want to use the USB interface for UART, you need to incorportae something like the USB CDC ACM Example into the application.

I run into the same issue.

Copied SDK 15.2 example examples\ble_peripheral\ble_app_uart\pca10056 into new pca10059 subfolder, changed board definition to BOARD_PCA10059 (tried both, armgcc and SES) and added pin definitions near the end of components\boards\pca10059.h:

#define RX_PIN_NUMBER  NRF_GPIO_PIN_MAP(0,10)
#define TX_PIN_NUMBER  NRF_GPIO_PIN_MAP(0, 9)
#define CTS_PIN_NUMBER NRF_GPIO_PIN_MAP(0,24)
#define RTS_PIN_NUMBER NRF_GPIO_PIN_MAP(0,22)

(Tried several pin assignments like 20,17,15,13 too).

Flashing with nRF Connect (Win10) succeeds, but the Dongle seems to crash immediately: no LEDs, no BLE advertising.

Really like the Dongle for prototyping and would like to understand how to get the peripherals used.
