|
|
This is a short program that is intended to be used only to validate voice entries
|
|
in the voice_lib.py file. It should only be used for building voice libraries and
|
|
only used during development to validate the entires.
|
|
|
|
It uses a number of hard-coded parameters, like the voice files to play back, the
|
|
slot, talkgroup, source, etc. of the originating stream.
|
|
|
|
It is not for novices to use, and should only be used by those comfortable with
|
|
how DMR packets are build and Python. It does not handle OpenBridge systems, only
|
|
HBP systems, and it is HIGHLY recommended to only use it against a single system
|
|
at a time.
|
|
|
|
It is a development and debugging tool and has no purpose in actual production
|
|
DMR networking systems.
