Hey, language. There are kids on the internet. BTW, your .service file
had the same bug with a small 'i' in Install, so it would not have worked
anyway. But as you said in your later post, you're not getting paid, so
I'm not here to quibble.
Anyway, I enabled the service, but it won't start due to some internal
error:
root@beaglebone:/tinkerforge/Example_project# systemctl start
imusend.service
Job for imusend.service failed because the control process exited with
error code.
See "systemctl status imusend.service" and "journalctl -xe" for details.

The shell file runs fine when I call it from the terminal:
/usr/bin/imuout.sh
But the system won't run it as a service for some reason.
/usr/local/lib/python2.7/dist-packages/tinkerforge/ip_connection.py", line
687 simply reads:
while self.receive_flag:
try:
data = self.socket.recv(8192)
except socket.error:
if self.receive_flag:
e = sys.exc_info()[1]
if e.errno == errno.EINTR:
continue
self.handle_disconnect_by_peer(IPConnection.DISCONNECT_REASON_ERROR,
socket_id, False)
break
687 if len(data) == 0:
if self.receive_flag:
self.handle_disconnect_by_peer(IPConnection.DISCONNECT_REASON_SHUTDOWN,
socket_id, False)
break
pending_data += data
This may be a bug in Python 2.7: http://bugs.python.org/issue14623
Per one recommendation:
The most simple workaround is to add timeout
time.sleep(1)
in the end of script that allows the threads to finish before the script
comes to end of life and close
Haven't figured out where to put a time.sleep(1) line.
