Thanks, Maria!

Thanks.

Yes, other examples were working properly.

We successfully make the nrf52-ble-image-transfer-demo work!

After debugging, we detected that the problem was in the SPI clock stability as suggested here (using the side connector):

Thanks!

Thank you very much for your support, Maria.

We will face other issues during this project but I think you can close the thread 🙂.

Hello,

[quote user=""]We are using the nRF52840 DK (PCA10056, 3.0.2, 2024.21) and the on Win10 with SDK 16.0.0 + s140_nrf52_7.0.1_softdevice.hex, and we ordered and are waiting for a J-Ling V9 for debugging (unfortunately, it did not come with the DK).[/quote]

[quote user=""]We also compile the code, but again, we do not get any feedback neither via Serial Terminal (v1.4.3).[/quote]

We have not configured the solder bridges SB10-15 and SB20-25 yet, as suggested,

, because after checking the DK schematic we understand it is only required by the front header configuration.

That is good to hear!
