I am using a photo detector to sense heart beat data. That sensor data is being sent to my nRF51 DK's ADC and then transmitted out via Bluetooth. I want to collect that data in real(ish) time, in Matlab, so that my team can start running some DSP analysis on the data. For our project we cannot work with past data, it needs to be current data -- within a second or two.
So, I am receiving the nRF 51 DK packets in a nRF dongle in my computer's USB port. I downloaded Master Control Panel and it's great, but my information is trapped inside! Right now I'm writing scripts that will parse the log.txt file that the MCP generates, but I fear this is going to be inefficient.
I am hoping that there is someone here who can point me in a better direction. I'm trying to create this data path.. sensor -> 51DK -> dongle -> matlab, all streaming. At this point I have the voltages I want showing up in the MCP log.txt, I am just not sure that opening and closing files 100's of times a second is the most effective means of streaming my packet data into matlab.
