I am tyring to implement a python program, using Twisted, to communicate
witha bluetooth device. The following is a sample code of what I have
implemented:
from twisted.internet import protocol, reactor
from twisted.internet.serialport import SerialPort
from twisted.protocols import basic
class DeviceBluetooth(basic.Int16StringReceiver):
def connectionMade(self):
print 'Connection made!'
self.sendString('[01] help\n')
def dataReceived(self, data):
print"Response: {0}".format(data)
print "-----"
print "choose message to send: "
print "1. Stim on"
print "2. Stim off"
print "3. Stim status"
print "4. Help"
# user input
ch = input("Choose command :: ")
if int(ch) == 1:
self.sendString('[02] stim on\n')
elif int(ch) == 2:
self.sendString('[03] stim off\n')
elif int(ch) == 3:
self.sendString('[04] stim ?\n')
elif int(ch) == 4:
self.sendString('[05] help\n')
else:
reactor.stop()
SerialPort(DeviceBluetooth(), 'COM20', reactor, baudrate=115200)
reactor.run()
When I run the program, sometimes I get a response and other times I do not
receive anything. And most of the times long responses are fragmented appear
as part of the next message. I have through the hyperterminal to make sure
that I get the appropriate response from by bluetooth device. So, the
problem has to be with my code.
Is there something that I doing wrong in my code?
