pure virtual |
Allows the modem driver to do its work.
Should be called regularly to perform the work of the driver as the driver does not run in its own thread. This allows us to guarantee that no signals are called except inside this method. Does not block.
Implemented in goby::acomms::MMDriver, goby::acomms::IridiumShoreDriver, goby::moos::BluefinCommsDriver, goby::acomms::IridiumDriver, goby::moos::UFldDriver, goby::acomms::BenthosATM900Driver, goby::acomms::ABCDriver, goby::acomms::UDPDriver, and goby::pb::PBDriver.
|
pure virtual |
Virtual initiate_transmission method. Typically connected to MACManager::signal_initiate_transmission() using bind().
m | ModemTransmission (defined in acomms_modem_message.proto) containing the details of the transmission to be started. This may contain data frames. If not, data will be requested when the driver calls the data request signal (ModemDriverBase::signal_data_request) |
Implemented in goby::acomms::MMDriver, goby::acomms::IridiumShoreDriver, goby::acomms::IridiumDriver, goby::moos::BluefinCommsDriver, goby::moos::UFldDriver, goby::acomms::BenthosATM900Driver, goby::acomms::ABCDriver, goby::acomms::UDPDriver, and goby::pb::PBDriver.

Starts the modem driver. Must be called before poll().
cfg | Startup configuration for the driver and modem. DriverConfig is defined in acomms_driver_base.proto. Derived classes can define extensions (see http://code.google.com/apis/protocolbuffers/docs/proto.html#extensions) to DriverConfig to handle modem specific configuration. |

boost::signals2::signal<void(protobuf::ModemTransmission* msg)> goby::acomms::ModemDriverBase::signal_data_request |
Called when the modem or modem driver needs data to send. The returned data should be stored in ModemTransmission::frame.
You should connect one or more slots (a function or member function) to this signal to handle data requests. Use the goby::acomms::connect family of functions to do this. This signal will only be called during a call to poll. ModemTransmission is defined in acomms_modem_message.proto.
Definition at line 96 of file driver_base.h.
boost::signals2::signal<void(protobuf::ModemTransmission* msg_request)> goby::acomms::ModemDriverBase::signal_modify_transmission |
Called before the modem driver begins processing a transmission. This allows a third party to modify the parameters of the transmission (such as destination or rate) on the fly.
You may connect one or more slots (a function or member function) to this signal to handle data requests. Use the goby::acomms::connect family of functions to do this. This signal will only be called during a call to poll. ModemTransmission is defined in acomms_modem_message.proto.

boost::signals2::signal<void(const protobuf::ModemRaw& msg)> goby::acomms::ModemDriverBase::signal_raw_incoming |
Called after any message is received from the modem by the driver. Used by the MACManager for auto-discovery of vehicles. Also useful for higher level analysis and debugging of the transactions between the driver and the modem.
If desired, you should connect one or more slots (a function or member function) to this signal to listen on incoming transactions. Use the goby::acomms::connect family of functions to do this. This signal will only be called during a call to poll. ModemRaw is defined in acomms_modem_message.proto.

boost::signals2::signal<void(const protobuf::ModemRaw& msg)> goby::acomms::ModemDriverBase::signal_raw_outgoing |
Called after any message is sent from the driver to the modem. Useful for higher level analysis and debugging of the transactions between the driver and the modem.
If desired, you should connect one or more slots (a function or member function) to this signal to listen on outgoing transactions. Use the goby::acomms::connect family of functions to do this. This signal will only be called during a call to poll. ModemRaw is defined in acomms_modem_message.proto.

boost::signals2::signal<void(const protobuf::ModemTransmission& message)> goby::acomms::ModemDriverBase::signal_receive |
Called when a binary data transmission is received from the modem.
You should connect one or more slots (a function or member function) to this signal to receive incoming messages. Use the goby::acomms::connect family of functions to do this. This signal will only be called during a call to poll. ModemDataTransmission is defined in acomms_modem_message.proto.

boost::signals2::signal<void(const protobuf::ModemTransmission& message)> goby::acomms::ModemDriverBase::signal_transmit_result |
