Python: the rb9704 command line, a fake modem, and the tests
rb9704 drives a 9704 on USB and the Cloudloop account behind it, moved from WII6's host/rockblock with its project names taken out. rb9704-fake speaks JSPR on a pty or a serial port: everything the library asks, MO in segments with the CRC checked, MT, signal, provisioning, refusals and failures on command. The tests run against the fake at every level: the fake itself, the command line, Ground Control's Python binding, the shell sample on native_sim, and the sample on a board (test_zephyr.py, one suite through two consoles). test_real.py makes free checks against a real modem.

"""
|
||||
rb9704 - drive a RockBLOCK 9704 from the host over its USB-C port.
|
||||
|
||||
rb9704 ports
|
||||
rb9704 [-p PORT] info
|
||||
rb9704 [-p PORT] signal [--watch S] [--every S]
|
||||
rb9704 [-p PORT] provision [--timeout S]
|
||||
rb9704 [-p PORT] jspr [LINE ...]
|
||||
rb9704 [-p PORT] send (--text T | --hex H | --file F) [--topic N] [--yes]
|
||||
rb9704 [-p PORT] listen [--out DIR] [--for S]
|
||||
rb9704 [-p PORT] session (--text T | --hex H | --file F) [--quiet S] [--yes]
|
||||
rb9704 cloud ping | things | mo | msg ID | mt ... | status ID
|
||||
|
||||
The modem side uses Ground Control's rockblock9704 package, a binding of
|
||||
the same C library this repository builds into Zephyr, so what works here
|
||||
is the library the firmware runs. `provision` and `jspr` speak
|
||||
JSPR directly over pyserial instead, because the library only asks for
|
||||
the provisioning when a message is sent, and asking that way is free.
|
||||
|
||||
`send` and `session` cost airtime and ask before sending; --yes skips the
|
||||
question. Everything else on the modem side is local serial traffic and
|
||||
costs nothing. `cloud mt` costs airtime too.
|
||||
|
||||
The port is -p, or $RB9704_PORT, or the one FTDI FT234XD attached (the
|
||||
9704's USB-C bridge, 0403:6015). --log FILE appends every event as a JSON
|
||||
line, for the bench log.
|
||||
|
||||
The cloud verbs talk to the Cloudloop Data API (api.cloudloop.com). The
|
||||
token is $CLOUDLOOP_TOKEN or the first line of ~/.config/rb9704/cloudloop.token;
|
||||
it never goes in a repository. docs/CLOUDLOOP.md says how to get one.
