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.

First things, put your camera aside for a while. Take UART and other ble examples and get them working. Get a feel of how BLE works. Once you familiar with data transmission over BLE, then you can get back to your camera. There are many examples in the sdk you can look at. If you are using Keil free licence, it is limited to 30KB. This is probably not enough for real work. There are Eclipse based development which is completely free. You look at this Blog site on how to setup up Eclipse based nRF51 development. It also contains many examples you can use, including UART over BLE. embeddedsoftdev.blogspot.ca/.../ehal-nrf51.html
