ble_app_interactive code for nRF52840 Dongle

[Rekha]

Hi i am working on nRF52840 Dongle , I could not find ble_app_interactive application for nrf52840 dongle,

i am trying to implement the same code with some modification as below:

changed Project->options->c/c++ compiler->Preprocessor

Defines:

BOARD_PCA_10059

NRF52840_XXAA

S140

but i am getting an error saying: Duplicate definition for UARTE0_UART0_IRQHANDLER

Please suggest if there is already ble_app_interactive example code exist for nRF52840 Dongle???

Hi.

How did you try to implement it?

Did you follow this tutorial?

I did a successfull implementation by following that tutorial.

These are the steps I did:

1.  Make a copy of the folder pca10056 in examples\ble_central_and_peripheral\experimental\ble_app_interactive

2. Renaming that folder pca10059

3. Chaning the preprocessor define BOARD_PCA10056 to BOARD_PCA10059

4. Open the file components\boards\pca10059.h

5. Adding the defines needed for configuring UART for CLI

#define RX_PIN_NUMBER  NRF_GPIO_PIN_MAP(1,10)
#define TX_PIN_NUMBER  NRF_GPIO_PIN_MAP(1,13)
#define CTS_PIN_NUMBER NRF_GPIO_PIN_MAP(1,15)
#define RTS_PIN_NUMBER NRF_GPIO_PIN_MAP(0,2)
#define HWFC           true

Then I compiled the project without any errors:

Try this.

Best regards,

Andreas

I am using IAR to compile the code and generate hex file.

I am using nrf connect for desktop to dump code into Dongle. I am getting following error:

please suggest what to do?

Thanks

Thank you. I will look into that DFU Trigger library

Hi.

Yes. But those were just arbitrary pin definitions, you still have to connect them to wires and a serial interface in order to make it work.

I only showed you how to define pins 1.10, 1.13, 1.15 and 0.02 as UART pins, as you can see these "pins" are not connected to anything, you have to solder on wires and connect them to a serial interface which you plug into your PC in order to make the UART work.

Best regards,

Hi here is the link why  i dint connect pins externally:

Hi.

The nRF52840 Dongle does not have an on-board Segger debugger chip like the nRF52 DK, therefore you cannot "read and display through that port". You have to wire and solder as I described below in order to make the UART work for the nRF52840 Dongle.

Best regards,

Andreas

Yes i tried this . it works. Thank you.
