I need help to build a demo of product consisting of BLE observer. I chose the nRF51822 due to lower cost, many choices for modules, and it does just what I need. I was able to set up the Segger IDE but then found out that the BLE observer example for the nRF51 DK/PCA10028 is not compatible. Does anyone have a recommendation? Of course, I would prefer having the example code for the BLE observer running on the Segger IDE, since my application will require only minor modification for this product demo. Also I cannot afford a Keil license.
