nrf51822 evaluation kit image from camera to BLE

[Dong Pham]

Hi Im electrical engineer student. I am working on nrf51822 evaluation kit and LinkSprite JPEG Color Camera UART Interface. I tried to control the camera to take picture, store in flash then from flash go straight to BLE. I get stuck at storing image to flash. The library in keil folder doesnt provide that much example. Is there anyone have a direction for me to continue this project? Thank you

You need to look at the pstorage. How big is the picture ? You only have a few KB in the nRF51 flash avail for storage.

I can't to your question about the camera protocol. You'll need to find the camera specification and understand the transfer protocol it uses to transfer data over uart. JPEG is a compressed image. You won't the picture itself but compressed data bitstream. In order to see the image you need to decode it first. You don't need to do that. Just sent all the data you receive and send it as it over BLE to whatever you use to decode the image. The nRF51 is not fast enough to decode the image in realtime.
