Hi, what exactly should we see as graphic from this example?

[chickenjohn]

it should display whatever you send from your bluetooth serial adapter

I mean...
leadii.bin send by python script - ecg graphic is bad.
Later I found, that If I send leadii.bin from terminal, graphic looks OK.
Is there any known issues?

Please, describe the data protocol.
