Always output empty objects or nothing at all where objects are expected, but
no elements exist.
Also remove a few unneeded "requires", a few basic modules are provided by
announce.lua by default.
This adds a new announce.d datum "neighbours" (alfred 160) containing
information about mesh neighbours. It's intended to be an replacement
for batadv-vis.
In addition to the data already provided by batadv-vis it'll also
provide information about direct wifi neighbours.
Unlike batadv-vis, no data about clients is transmitted.
Sample data:
{
"wifi": {
"90:f6:52:82:06:02": {
"neighbours": {
"f8:d1:11:2c:a7:d2": {
"noise": -95,
"inactive": 0,
"signal": 0
},
"96:f6:52:ff:cd:6f": {
"noise": -95,
"inactive": 0,
"signal": -37
}
}
}
},
"batadv": {
"90:f6:52:82:06:02": {
"neighbours": {
"96:f6:52:ff:cd:6f": {
"lastseen": 2.8500000000000001,
"tq": 177
}
}
},
"90:f6:52:82:06:03": {
"neighbours": {
"f8:d1:11:2c:a7:d3": {
"lastseen": 2.3500000000000001,
"tq": 206
}
}
}
},
"node_id": "90f652820602"
}
This adds a `node_id` to announce.d. `node_id` is an hex-number uniquely
identifying a particular node. On nodes having a
primary MAC this MAC address will be used as `node_id` (sans the
colons). The value is opaque. It must not be converted back into
a MAC address.
`node_id` should be sent in all alfred and announced packets to
ensure clients can link the data to a particular node.
All announce.d scripts have been moved to /lib/gluon/announce/announce.d
The script /lib/gluon/announce/announce.lua will collect all information
and output json.
