The overall BabbleSim documentation provides information about BabbleSim's architecture, as well as general information on this physical layer.
There you can also find some simple usage examples.
This Phy accepts many command line parameters, for more information about these,
you can run it with the --help option.
For more details about the design of this Phy please check README_design.md.
For information about how to select a different channel or modem model check this page. For information about how to implement a new channel or modem model, check README_channel_and_modem_if.md
The interface between the simulated devices and this Phy is provided by ext_2G4_libPhyComv1. Please refer to its documentation for more information about the exact protocol and the messages which each device exchanges with this Phy.
A device is free to advance its simulated time even before it gets
a response to a request and to pipe several consecutive requests.
This can be done easily and safely for Tx and Wait requests.
It would be more difficult though for a device to be able to
pipe any request after a Rx, RSSI, or CCA attempt.
But this Phy follows the principle of not responding to a request until the
time in which that request would have been completed.
Note that piping several requests ahead of time will greatly increase the speed of the simulation if there is free CPU cores. Even if there is no free CPUs, it will overall increase performance by decreasing the number of required context switches.
