I have two questions I want to ask in relation to the SHIMMER.
Firstly in relation to the maximum throughput of data over the Bluetooth radio, to test this I have set up the Shimmer to constantly call the Bluetooth.write() function and am using modified code from simpleAccel.py to monitor the throughput (using time.time() phyton calls after bytes are received). I am noticing that even with a looping continuous write call (Shimmer code doing nothing else) the maximum throughput I am achieving is generally around the 10KB/s mark. I would have thought I would be able to achieve much higher, any thoughts on how I would go about increasing this? Secondly I am also trying to incorporate the Bluetooth functionality into the JustFATLogging application. However the modification I am adding is I want the to perform read operations on the SD card after the writes have taken place and then stream those values. I have successfully added in the Bluetooth functionality. However I have tried adding in FatFs.read() calls but this operation never seems to be carried out, is there some code I need to add to ensure the SD card can be read from or anything else I need to do for this? Any help with this would be appreciated, thanks, Darren
