nrf52-ble-image-transfer-demo for nRF52840 Dongle

[Paul M.]

Hello everyone!
I'd like to implement the nrf52-ble-image-transfer-demo with a nRF52840 Dongle, for a small low-power image transfer application. My question now is, how do I need to alter the code so it would run on the dongle?

Thanks for your help,

Paul

Hi Torbjørn,

Thanks for your answer! I got the example to build this way as well. However, I cannot write it on the dongle. I do think however that the problem there is somewhere else. As I understood it, to program the dongle I need to generate the HEX file of the code, copy this file into the programmer of the nRF Connect for Desktop, and then simply write it onto the dongle. I have put the dongle into bootloader mode by pressing the reset button beforehand. The programmer then asks for a user input: "please select the SoftDevice required by the application firmware", and gives me a bunch of options to choose from. This, however, gets not asked if I simply try to write the blinky example onto the dongle. 

Would you happen to know where the problem is here?

Thank you very much,

Paul

I was able to write it onto the dongle by adding the s140_nrf52_7.0.1_softdevice.hex file

Hi Paul

That is good news. Does the application seem to run OK?

If everything is working you should see it advertise. 

Best regards
