Help on class GsmModem in module pygsm.gsmmodem: class GsmModem(__builtin__.object) | | pyGSM is a Python module which uses pySerial to provide a nifty | interface to send and receive SMS via a GSM Modem. It was ported | from RubyGSM, and provides (almost) all of the same features. It's | easy to get started: | | # create a GsmModem object: | >>> import pygsm | >>> modem = pygsm.GsmModem(port="/dev/ttyUSB0") | | # harass Evan over SMS: | # (try to do this before 11AM) | >>> modem.send_sms("+13364130840", "Hey, wake up!") | | # check for incoming SMS: | >>> print modem.next_message() | <pygsm.IncomingMessage from +13364130840: "Leave me alone!"> | | | There are various ways of polling for incoming messages -- a choice | which has been deliberately left to the application author (unlike | RubyGSM). Execute `python -m pygsm.gsmmodem` to run this example: | | # connect to the modem | modem = pygsm.GsmModem(port=sys.argv) | | # check for new messages every two | # seconds for the rest of forever | while True: | msg = modem.next_message() | | # we got a message! respond with | # something useless, as an example | if msg is not None: | msg.respond("Thanks for those %d characters!" % | len(msg.text)) | | # no messages? wait a couple | # of seconds and try again | else: time.sleep(2) | | | pyGSM is distributed via GitHub: | http://github.com/adammck/pygsm | | Bugs reports (especially for | unsupported devices) are welcome: | http://github.com/adammck/pygsm/issues | | | | | Methods defined here: | | __init__(self, *args, **kwargs) | Creates, connects to, and boots a GSM Modem. All of the arguments | are optional (although "port=" should almost always be provided), | and passed along to serial.Serial.__init__ verbatim. For all of | the possible configration options, see: | | http://pyserial.wiki.sourceforge.net/pySerial#tocpySerial10 | | boot(self, reboot=False) | Initializes the modem. Must be called after init and connect, | but before doing anything that expects the modem to be ready. | | command(self, cmd, read_term=None, read_timeout=None, write_term='\r') | Issue a single AT command to the modem, and return the sanitized | response. Sanitization removes status notifications, command echo, | and incoming messages, (hopefully) leaving only the actual response | from the command. | | connect(self, reconnect=False) | Creates the connection to the modem via pySerial, optionally | killing and re-creating any existing connection. | | disconnect(self) | Disconnects from the modem. | | hardware(self) | Returns a dict of containing information about the physical | modem. The contents of each value are entirely manufacturer | dependant, and vary wildly between devices. | | next_message(self, fetch=True) | Returns the next waiting IncomingMessage object, or None if | the queue is empty. The optional _fetch_ parameter controls | whether the modem is polled before checking, which can be | disabled in case you're polling in a separate thread. | | ping(self) | Sends the "AT" command to the device, and returns true | if it is acknowledged. Since incoming notifications and | messages are intercepted automatically, this is a good | way to poll for new messages without using a worker | thread like RubyGSM. | | query(self, cmd) | Issues a single AT command to the modem, and returns the relevant | part of the response. This only works for commands that return a | single line followed by "OK", but conveniently, this covers almost | all AT commands that I've ever needed to use. | | For all other commands, returns None. | | send_sms(self, recipient, text) | Sends an SMS to _recipient_ containing _text_. Some networks | will automatically chunk long messages into multiple parts, | and reassembled them upon delivery, but some will silently | drop them. At the moment, pyGSM does nothing to avoid this, | so try to keep _text_ under 160 characters. | | signal_strength(self) | Returns an integer between 1 and 99, representing the current | signal strength of the GSM network, False if we don't know, or | None if the modem can't report it. | | wait_for_network(self) | Blocks until the signal strength indicates that the | device is active on the GSM network. It's a good idea | to call this before trying to send or receive anything.
