Brian,
Depending on your needs there are three ways to accomplish this. The
first uses the lowest level API, emanesh.ControlPortClient:
[=== begin method 1 ===]
#!/usr/bin/env python
import sys
from emanesh import ControlPortClient, ControlPortException
client = ControlPortClient('localhost', 47000)
# You will need to determine the build Id for the component you wish
# to update. For this example we will search for the first RF Pipe
# radio model.
firstRFPipeBuildId = None
# Retrieve the running component manifest. This is the information
# available from the 'emanesh show' command.
for nemId,components in client.getManifest().items():
if firstRFPipeBuildId == None:
for buildId,componentType,plugin in components:
if plugin == 'rfpipemaclayer':
# Output for illustrative purposes only
print 'Found nem id:',\
nemId,\
'build id:',\
buildId,\
'type:',\
componentType,\
'plugin:',\
plugin
# Store the build id
firstRFPipeBuildId = buildId
break
else:
break
if firstRFPipeBuildId != None:
try:
client.updateConfiguration(firstRFPipeBuildId,
[('datarate',
ControlPortClient.TYPE_UINT64,
(1000000,))])
except ControlPortException as exp:
print >>sys.stderr,exp
else:
print >>sys.stderr, "unable to locate RF Pipe radio model instance"
client.stop()
[=== end method 1 ===]
The second method uses emanesh.EMANEShell. This is simpler but requires
you to conform to emanesh syntax:
[=== begin method 2 ===]
#!/usr/bin/env python
from emanesh import EMANEShell
shell = EMANEShell('localhost',47000)
shell.onecmd('set config 1 mac datarate=1000000')
shell.onecmd('exit')
[=== end method 2 ===]
The third method is available if you wish to script a scenario that
changes configuration at set time points. You can use the
emanecommand-eel command:
# emanecommand-eel /path/to/your/scenario/command.eel
where,
# cat /path/to/your/scenario/command.eel
5.0 localhost:47000 emanesh set config 1 mac datarate=1000000
emanecommand-eel uses method 2.
