1. add network channel switch function.
- users can obtain the new channel through the event MESH_EVENT_CHANNEL_SWITCH.
- the entire network will be moved to the same channel as the router without user intervention.
- if no router is in the network, users can call esp_mesh_switch_channel() on the root side to
move the entire network to their desired channel.
2. support not configuring the network channel.
3. support not configuring the router BSSID even if the router is hidden.
4. add allow_channel_switch to mesh configuration.
- if the channel is not specified, this value will be ignored.
- if the channel is specified and this value is set, when "fail" (mesh_attempts_t) times of parent selection
or look for networks are reached, device will change to perform a full channel scan for networks that could join.
- if the channel is specified and this value is set to 0, when a root is not elected, channel switch is not allowed.
but when a root appears, the root performs a full channel scan during the process of connecting to the router,
so even allow_channel_switch is set to 0, the root may still switch channel and eventually the entire network
changes channel.
5. add allow_router_switch to mesh router configuration.
- if the BSSID of router is not specified, this value will be ignored.
- if the BSSID of router is specified and this value is set, when the router of this specified BSSID fails to be found
after "fail" (mesh_attempts_t) times, the entire network is allowed to switch to another router with the same SSID.
6. modify the root to perform a full channel scan when esp_wifi_connect().
7. support handling beacon without DS Paramter Set.

Mesh Internal Communication Example
This example demonstrates how to use the mesh APIs to set up a mesh network, send and receive messages over the mesh network and etc.
Features Demonstrated
-
mesh initialization
-
mesh configuration
-
mesh start
-
mesh event handler
-
root send and receive
-
other nodes receive
Run make menuconfig to configure the mesh network channel, router SSID, router password and mesh softAP settings.
When the mesh network is established and if you happen to run this example on ESP-WROVER-KIT boards, the RGB light indicator will show you on which layer devices are. The pink reprents root; the yellow reprents layer 2; the red reprents layer 3; the blue reprents layer 4; the green reprents layer 5; the white reprents layer greater than 5. Root continuously sends an On / Off control message to all devices in its routing table. Devices including root itself receive this message and do the On / Off.
