CC2640R2F: Sensor Controller Studio Multi-Buffered ADC got stuck

Other than this problem, I tried to implement custom multiple buffer. I got the same error.  

!! Another update:  The Actual Data Streamer project got stuck in the same place. I couldn't understand why it doesn't work. 

Hi AB,
Thanks for the help. For now I changed the implementation something like below: It works. I am sending these buffers to Android phone via BLE. However, I see so much jitters in the graph (it is for plotting the data in android). What can I do to eliminate these jitters?
Thanks.

I do not have the lab equipment to realize a pre-determined signal. However I saved a log file to examine the incoming data. I had interesting results: In the text document, every 123 data corresponds to 1 packet and the data belongs to a sinusoidal wave (with DC). The packet itself seems correct because it is compatible with the wave. However between the packages there is always jump as far as I can see. What is the reason for that and how can I fix it? 
Thanks.

Here is the jittery plot. It seems like a periodic error occurs.

I figured out the problem. I assigned the array as 123 + 1(flag). I directly send this buffer using BLE. I misunderstood the Data Length Extension concepts. Here is what it should be:

The maximum allowed PDU is 251, therefore maximum MTU can be 247. Because it is notificatication characteristic, maximum size can be 244 bytes. When I decreased my buffer size to 121 +1 (uint16), the number of jumps decreased, but not completely.
