The transport properties client is a [BSP client](BSP) that synchronises transport properties between pairs of devices. Transport properties describe how to connect to a device over various transports.
### Group identifiers
### Identifier
The client's identifier is `org.briarproject.bramble.transport`.
The client's identifier is `org.briarproject.bramble.transport`. The major version is 0.
The client uses a separate group for each pair of contacts. The [group descriptor](BSP#group-identifiers) is a [BDF list](BDF) containing the unique IDs of the contacts' identities, sorted in ascending order as byte strings.
### Groups
The client uses a separate BSP group for communicating with each contact. The [group descriptor](BSP#group-identifiers) is a [BDF list](BDF) containing the unique IDs of the contacts' identities, sorted in ascending order as byte strings.
The client also uses a group with an empty descriptor for storing local transport properties. This group is not shared with any contacts.
### Message types
**UPDATE** - The message body is a BDF list with three elements: `transportId` (string), `version` (int), and `properties` (dictionary). `transportId` and `properties` are supplied by the transport plugin. `version` is incremented whenever the properties change.
