Read Thread takes more time reading large bytes #308

Closed sivaprashanth closed 4 years ago

sivaprashanth commented 4 years ago

First i connect serially with the streams example as shown, then once i create a status timer as shown below the usb device stops reading :
if (status_timer != null) return; status_timer = new Timer(); TimerTask updateProfile = new StatusTimerTask(this); Log.d(TAG2,"Status Timer created"); Global gs = (Global) getApplication(); if(!gs.mQblockSettings.isUSBMode) status_timer.scheduleAtFixedRate(updateProfile, 0, 200); else status_timer.scheduleAtFixedRate(updateProfile, 10, 1000);

i saw that if i disconnect the usb from the device the read thread again starts back. I infered this through my log messages.Anyone have any idea about it please help me.

but somehow if i start my timertask after the connection has been made then it works fine. I dont know whether the timer is stopping the service thread or not.

i am reading 1024 bytes of information as a stream. it seems to take a minute to read them at baud rate 9600. i am using aysn api with chipset CH34X device. is there another approach to read the thread faster?

the issue is with the baud rate. changing the baud rate 115200 worked fine with this library itself.
