v3.9.0

features:

• read() with timeout now allows unlimited read size for Android 9+
• SerialInputOutputManager now executes read and write in separate threads, so writeAsync is executed now immediately and not delayed any more until a read succeeded or timed out.

changes:

• before was possible to start SerialInputOutputManager with Executors.newSingleThreadExecutor().submit(ioManager). Now you have to use ioManager.start() as already used in the example.

v3.8.1

fixes:

• values supported by default setFlowControl() consistent with getSupportedFlowControl()
• catch all Throwables from SerialInputOutputManager.Listener methods (#601)
  to avoid breaking Interface changes, Error from onNewData() is wrapped into Exception when calling onRunError()

v3.8.0

features:

• flowcontrol for ftdi, pl2303, cp210x

v3.7.3

fixes:

• improved error handling for read() with concurrent close() (#569).
  (reworked previous solution from change 8b9ad7e / v3.7.1 because closeInt() was not working any more)
• write() throws SerialTimeoutException if connection still valid, instead of IOException which is typically handled as connection lost
• SerialInputOutputManager.writeAsync() handles SerialTimeoutException internally

v3.7.2

fixes:

• handle uncaught NPE causing App termination in prolific driver controlline background thread (issue was introduced in v3.7.1)

v3.7.1

changes:

• Add read() and write() with length argument (#544)
• improved error handling for read() with concurrent close() (#569)
  • isOpen() returns false during concurrent close()
  • less tracing in SerialInputOutputManager

v3.7.0

features:

• new Chrome OS CCD (Closed Case Debugging) ChromeCcdSerialDriver (#540)

changes:

• consolidate control line method results, if no control lines supported (GsmModemSerialDriver, ChromeCcdSerialDriver):
  • getSupportedControlLines returns EnumSet.noneOf(ControlLine.class)
  • getControlLines() throws UnsupportedOperationException, similar to get/set<SingleControlLine>()

v3.6.0

fixes:

• return Connection closed IOException from read on concurrent close instead of NPE

features:

• improved composite CDC devices support:
  • skip non ACM control interfaces
  • get correct ACM data interface from IAD
• new GsmModem device driver, e.g. for Unisoc based Fibocom GSM modems (#521)
• moved util/HexDump.java from example to library

v3.5.1

fixes:

• support composite CDC devices with non-consecutive interface IDs

v3.5.0

fixes:

• skip RNDIS related data interfaces in composite CDC devices

features:

• probe CDC devices by USB interface types instead of fixed VID+PID
  • no more custom prober required for standard CDC devices
  • legacy (singleInterface) CDC devices still have to be added by VID+PID
  • for autostart VID+PID still have to be added to device_filter.xml
