[Feature] Runtime EMANE config updates (The questions of session.emane.setconfig and Emane noisemode change)

[GLtangzero]

Q1:

from core import utils

# standardized way to retrieve an appropriate config id
# iface id can be omitted, to allow a general configuration for a model, per node
config_id = utils.iface_config_id(node.id, iface_id)
# set emane configuration for the config id
session.emane.set_config(config_id, EmaneIeee80211abgModel.name, {
    "unicastrate": "3",
})

The current code in core do not have the function of session.emene.setconfig, is there other function to realize it?

Q2:
The core will load the setting in emanephy.xml, but even the noisenode change to any other value, when the session is running the noisenode still keep the value of none.

I test the up question both in the code of tutorial7:

from core.api.grpc import client
from core.api.grpc.wrappers import Position, NodeType
from core.emane.models.ieee80211abg import EmaneIeee80211abgModel


def main():
    # interface helper
    iface_helper = client.InterfaceHelper(
        ip4_prefix="10.0.0.0/24",
        ip6_prefix="2001::/64",
    )

    # create grpc client and connect
    core = client.CoreGrpcClient()
    core.connect()

    # create session
    session = core.create_session()

    # create nodes
    position = Position(x=375, y=500)
    emane_net = session.add_node(
        _id=1,
        _type=NodeType.EMANE,
        name="emane1",
        position=position,
        emane=EmaneIeee80211abgModel.name,
    )
    position = Position(x=250, y=250)
    node2 = session.add_node(_id=2, model="mdr", name="n2", position=position)
    position = Position(x=500, y=250)
    node3 = session.add_node(_id=3, model="mdr", name="n3", position=position)

    # create links to emane
    node2_iface = iface_helper.create_iface(node_id=node2.id, iface_id=0)
    node2_iface.ip4 = "10.0.0.1"
    node2_iface.ip4_mask = 32
    node2_iface.ip6 = "2001::1"
    node2_iface.ip6_mask = 128
    session.add_link(node1=node2, node2=emane_net, iface1=node2_iface)
    node3_iface = iface_helper.create_iface(node_id=node3.id, iface_id=0)
    node3_iface.ip4 = "10.0.0.2"
    node3_iface.ip4_mask = 32
    node3_iface.ip6 = "2001::2"
    node3_iface.ip6_mask = 128
    session.add_link(node1=node3, node2=emane_net, iface1=node3_iface)

    # start session
    core.start_session(session=session)


if __name__ == "__main__":
    main()

CORE does not have any built in support for runtime config editing. You can use EMANE directly. I would look into their documentation or can use command line, like below from what I am seeing.

emanesh node-1 set config nems mac delay=1.5

Hello @bharnden:
Thanks for your reply, but actually I want ask about the presetting, it's meaning before we start the simulation.
Currently when I change the parameter in /usr/share/emane/manifest/emanephy.xml or /usr/share/emane/manifest/ieee80211abgmaclayer.xml the mostly parameters will change when I start the new simulation, but the parameter of noisemode is not change whatever the value I have setting.

Hi:
Actually I just a new one in the core and emane, so I still have some other question:
Q1:
If I change the setting in mac and phy, should I change all of changes in all nodes?(even the emane cloud node)
Q2:
In the tutorial7, the current scenario.xml works good, but when I change the noisemode to all, the nodes can't connect anymore, I attached the changed xml document.

noise_mode.xml

Thanks of your patience!
