Image transfer demo

[Blaugranas23]

Hi guys! I have had an issue with Image Transfer Demo project. I use nRF52832 with OV2640 camera. I used installation project process described on the page https://github.com/NordicPlayground/nrf52-ble-image-transfer-demo#softdevice-version. The project was successfully compiled an launched on Nordic. Then i downloaded application for Android "ImageTransferDemo". Connection between Android app and the nRF is successfully established and when i try "Take Picture" from the app transmission of Packets normally executes, but picture doesn't appear into app after receiving packets. What the reason could be? Thanks...

Hi 

What model of phone are you using?

Are you able to take a screenshot of the app after the transfer has stopped?

Best regards

Hi

Do you have any other phones you can test with to see if the issue is the same?

Also, do you have a link to the camera module you have?
There are a couple of different version on the market, and they might behave slightly differently. 

Best regards

Good morning!

Yes, we have checked the application with different phones, particularly with Samsung note 8.

Link to camera we used https://www.amazon.com/Arducam-Module-Megapixels-Arduino-Mega2560/dp/B012UXNDOY.

Thanks,

Best regards!

Hi

Can you try to comment out line 796 of main.c and see if it works better?
https://github.com/NordicPlayground/nrf52-ble-image-transfer-demo/blob/master/main.c#L796

On some variants of the sensor this line is not needed, and having it in will cause problems.
