there are various methods to improve throughput:
- use a background thread like SerialInputOutputManager to read permanently with infinite timeout and only send events to the main thread
- to reduce work in the main thread, merge events into a queue and handle as bulk event like done here
Hi, We are currently using the library as a plugin for a Unity app.
Unity script refresh rate is 30Hz so we are polling
port.read()every ~30mS. Device is sending continous data at 9600 baud but we are loosing packets.1) Is there any "interrupt driven" usage of the library in order to buffer incoming data? 2) Is this a common/know limitation of Android USB API? If so, whats the procedure to handle this?
Lastly, we are in doutb why the "protocol header" is 2 bytes?. We always seem to have 2 bytes more thant the returned by port.read(). ie: device sends 0x01-0x02-0x03-0x04, port.read() returns 2.
