I am currently using the library with multiple xbee devices configured as
DigiMesh. I use an asynchronous callback function for reading data and I
asynchronously call the write function through the use of other callback
inputs. Each xbee device may be tasked with sending and receiving copious
amounts of data between computers. I occasionally receive the following error:
Exception in thread Thread-5:
Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 551, in __bootstrap_inner
self.run()
File "/usr/local/lib/python2.7/dist-packages/xbee/base.py", line 95, in run
self._callback(self.wait_read_frame())
File "/usr/local/lib/python2.7/dist-packages/xbee/base.py", line 399, in wait_read_frame
frame = self._wait_for_frame()
File "/usr/local/lib/python2.7/dist-packages/xbee/base.py", line 131, in _wait_for_frame
byte = self.serial.read()
File "/usr/lib/python2.7/dist-packages/serial/serialposix.py", line 456, in read
raise SerialException('device reports readiness to read but returned no data (device disconnected?)')
SerialException: device reports readiness to read but returned no data (device
disconnected?)
Sometimes the error happens immediately, while sometimes it takes time before
it occurs. I can also say that it is not due to a bad connection as I have
confirmed the connection as well as on various different vehicles. I am
curious as if it is due to multiple writes and reads possibly colliding as I
did not see any protection against this.
I appreciate any help someone could give.
