The mesh module sends packets using multi-hop routing to a specified receiver somewhere in the network.
Channels
The mesh module uses 3 channel; one for the multi-hop forwarding (multihop) and two for the route disovery (route-discovery).
| void mesh_close |
( |
struct mesh_conn * |
c | ) |
|
Close an mesh connection.
- Parameters
-
| c | A pointer to a struct mesh_conn This function closes an mesh connection that has
previously been opened with mesh_open().
This function typically is called as an exit handler. |
- Examples:
- example-mesh.c.
Definition at line 177 of file mesh.c.
| void mesh_open |
( |
struct mesh_conn * |
c, |
|
|
uint16_t |
channels, |
|
|
const struct mesh_callbacks * |
callbacks |
|
) |
| |
Open a mesh connection.
- Parameters
-
| c | A pointer to a struct mesh_conn |
| channels | The channels on which the connection will operate; mesh uses 3 channels |
| callbacks | Pointer to callback structure This function sets up a mesh connection on the
specified channel. The caller must have allocated the
memory for the struct mesh_conn, usually by declaring it
as a static variable.
The struct mesh_callbacks pointer must point to a structure
containing function pointers to functions that will be called
when a packet arrives on the channel. |

| int mesh_ready |
( |
struct mesh_conn * |
c | ) |
|
Test if mesh is ready to send a packet (or packet is queued)
- Parameters
-
| c | The mesh connection on which is to be tested |
- Return values

| int mesh_send |
( |
struct mesh_conn * |
c, |
|
|
const linkaddr_t * |
dest |
|
) |
| |
Send a mesh packet.
- Parameters
-
| c | The mesh connection on which the packet should be sent |
| dest | The address of the final destination of the packet |
- Return values
-
| Non-zero | if the packet could be queued for sending, zero otherwise This function sends a mesh packet. The packet must be
present in the packetbuf before this function is called.
The parameter c must point to an abc connection that
must have previously been set up with mesh_open(). |
