Hi Bob,
Thanks for your reply!
I thought 56 kbps should be easily obtainable but didn't know
what the upper limit might be. For testing I am using an Asus Transformer
Prime which has a quad processor. I thought maybe the debugger might be
slowing it down so I exported the apk, installed the app directly and
turned USB debugging in my tablet off via "Settings", all to no avail. I
presume that should have rid the app of possible debug delays???
My app is data acquisition from an external device that will
eventually be graphically displayed in a GUI window. I decided I wanted to
display the data as text to start with and then move on to the graphics
display.
I don't have any problem displaying the data with SENA's
bluetooth terminal software. Thus I am absolutely sure of the quality of
the data and the BT interface.
I am now considering the use of the Amarino bluetooth API
which also is capable of capturing the data without a glitch. But it would
result in another software tier that I would prefer to avoid.
TMA
