100% cpu hang

[oroulet]

Hi, I just received a new device and I am trying to make it work. but the rfcom sample just hangs with 100%cpu. How can I debug that kind of thing? I tried to add debug from asyncio import get_event_loop from logging.config import dictConfig from sys import stdout

LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'standard': { 'format': '%(asctime)s %(levelname)-8s %(name)-35s %(message)s' }, }, 'handlers': { 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', 'stream': stdout, 'formatter': 'standard' }, 'file': { 'level': 'DEBUG', 'class': 'logging.handlers.RotatingFileHandler', 'formatter': 'standard', 'filename': '/tmp/rfxcom.log', 'maxBytes': 10 * 1024 * 1024, }, }, 'loggers': { 'rfxcom': { 'handlers': ['console', 'file', ], 'propagate': True, 'level': 'DEBUG', } }, }

from rfxcom.transport import AsyncioTransport

dev_name = '/dev/serial/by-id/usb-RFXCOM_RFXtrx433_A1XPT6J4-if00-port0' loop = get_event_loop()

def handler(packet):

Print out the packet - the string representation will show us the type.

print(packet)

# Each packet will have a dictionary which contains parsed data.
print(packet.data)

# You can access the raw bytes from the packet too.
print(packet.raw)

try: dictConfig(LOGGING) rfxcom = AsyncioTransport(dev_name, loop, callback=handler) loop.run_forever() finally: loop.close()

Hi,

I'm out on vacation for two weeks from today. I can try and help you when I get back if you still need it.

Sorry I can't help sooner.

when hanging the red led on the box is solid red until I ctrl-C

I don't know if it is the same problem, but I notice that rfxcom module was taking 100% CPU without hanging. I made a cProfile and saw that it was in the python3.4/asyncio/base_events.py, python3.4/selectors.py and python3.4/asyncio/selector_events.py that were the main cpu time. cf http://stackoverflow.com/questions/31526544/asyncio-python-module-takes-100-cpu

If someone has a clue...

Sorry, this project is not currently maintained by me. I would support anyone that wants to take it on.

I believe this was fixed by #21
