Ok. Seeing as that is a refinement of this question, with more information, I will close this ticket.
The discussion will continue in the other ticket.

Hi, I wrote another question (here : Link to question) with more detailed information of the problem I am encountering

Hi,

Sorry for my late reply.
The Dongle Programming Tutorial is the reference for how to make the examples compatible with the dongle.
You are currently attempting the BLE Blinkey example. Have you tried to do the non-ble(without softdevice) Blinkey example first, before doing the BLE one?

Please elaborate on the exact errors you are encountering. If you could provide a log of the building output that would be beneficial.

Best regards,
Karl

I think the problem is coming from the linker part, I am entering ( FLASH_PH_START=0x0;FLASH_PH_SIZE=0x100000;RAM_PH_START=0x20000000;RAM_PH_SIZE=0x40000;FLASH_START=0x1000;FLASH_SIZE=0xDF000;RAM_START=0x20000008;RAM_SIZE=0x3FFF8 )

is there any reference on how to set up the linker?

No problem, I am trying to download to the USBD BLE UART example in the nrf5240 dongle by referring to the nRF52840 Dongle Programming Tutorial . But when I do the modifications of the linker and processor, I am encountering errors when building the project. Is there any more references on what to modify to make an nrf52 DK software compatible with nrf52 dongle?

Yes, this is correct. I should instead have referred you the USBD BLE UART example for this, my apologies.
This example communicates between the PC and Dongle using a virtual COM port, instead of UART.
Note that this example is made for communicating with the nRF UART application for smartphones, so you will have to make changes to the example so as to communicate with your DK.

Sorry for any confusion this might have caused.

Best regards,
Karl

Yes, you understood my request.

I have a last question regarding the dongle. I read that the dongle does not have a UART to communicate with the PC, but a serial communication can happen through the USB. Do I have to change the coding of the " BLE Central nordic uart example" to operate by USB?

Hi,

Yes, there are many ways to go about achieving this.
Have you seen the Nordic UART example from the SDK?
The example demonstrates how you can pair two devices, and have them transmit what they receive on UART to each other.
The Dongle could run the BLE Central nordic uart example and the DK could run the UART/Serial port emulator example, to demonstrate this.

You then just need to modify the application running on the DK, to sent the sensor data rather than UART data.

Is this what you were looking for?

Best regards,
Karl
