Image Transfer Demo won't work

[leojg]

Hello, I'm having trouble to make the image transfer demo work.

I flashed the .hex files found here: https://github.com/NordicPlayground/nrf52-ble-image-transfer-demo to the board and nothing happens. I don't even see the device when scanning.

I got a nRF52840 board and a 2mp arducam connected in the side connector from p27 to p12 and with the arducam VDD pin going to the 5v pin in the other side of the board.

I also tried other pre compiled .hex examples that come with the SDK 13 and they seem to work, for example the ble_app_uart will show in the scanning.

I also tried to compile the source code via make and get the following error:

Compiling file: main.c

In file included from ../../../main.c:67:0:

../../../ble_image_transfer_service.h:133:1: error: '__packed__' attribute ignored [-Werror=attributes]

 }ble_its_ble_params_info_t;

 ^

../../../main.c:69:25: fatal error: cl_includes.h: No such file or directory

cc1: all warnings being treated as errors

compilation terminated.

I'm working in Mac so I can't install Keil 5, but I tried on Segger and I also got a similar error.

Could you point me in some direction about what I'm doing wrong?

Thanks!

Hi 

Did you flash the S140 SoftDevice before you flashed the application hex?
Otherwise it will not work. 

The current project has only been tested with Keil unfortunately, so I don't know what is the problem with make files.

I am working on a new version of the example that is updated with SDK v15 support and Segger project files, but I haven't released it yet because there are some issues with the transfer speed (it's not as fast as the old version). 
If you still can't make it work with the hex files I can provide you a zip of the new version in case it can be of some help, just be aware that it seems to run slower on some phones.

Best regards

Hello,

Yeah I flash the s140_nrf52840_5.0.0-2.alpha_softdevice.hex first and then the nrf52840_xxaa_side_header.hex

If you can send me a zip with the new version that would be great, im not concerned with the speed right now :D

Thanks a lot!

Hi

I attached the current state here. 

Unfortunately there is some issue with the PCA10056 version, and the SPI communication doesn't work properly when I try to take a picture. The PCA10040 version works fine. 

Could you try it out and see if you have more luck?

Tomorrow is my last day before I leave for vacation, so I can't guarantee that I will be able to solve the issue in time. 

Best regards
Torbjørn

Happy to help ;)

Just let me know once you have some time to test it.
