Currently only keep func pointer for the followings:
- Invalid parameter (mesh btc & mesh stack)
- Out of memory (mesh btc & mesh stack)
- Unknown act (mesh btc)
- Invalid model user data (mesh stack)
- BT_DBG("%s", __func__) (mesh btc & mesh stack)
- A few other specific situations (buf ref debug, send status check)
Different bluetooth host has different behaviors, so it's better
to maintain a scan check mechanism of BLE Mesh itself.
Fixes an issue when only PB-GATT is enabled for node, which will
output a scan error log when the device is provisioned.
This commit fixes a bug as well as changes a behaviour.
Bugfix: During softap/httpd based provisioning, if a session was closed
midway and a new one started, it would never proceed if the http server
assigns same socket number to the new session (which happens almost always).
Now, if a session is closed, using the http callbacks, the older session
data is cleared so that a new one can be created.
Behavioural change: If a client (mobile app particularly) does not use
persistent http session i.e. all provisioning communication on the same
socket, the provisioning may fail. Earlier, since the session context was
not getting cleared, even if the client closed a session and continued
on a new one, it would go through if the socket number assigned was same
(which happens almost always).
Ideally, from a security perspective, all communication related
to secure provisioning must happen on the same socket, and so, this
change is required.
1. If the root is specified (FIXED-ROOT) by set type or set parent, change ie.mesh_type to MESH_ROOT before connect to router.
2. Release esp_mesh_recv_toDS when the root becomes non-root.
3. esp_mesh_set_type now supports MESH_IDLE and MESH_STA.
4. Fix ie.rc_rssi is not updated during scan and vote.
5. Fix ie.mesh_type do not match ie.layer caused by parent switch.
6. Fix during root switch, the original root doesn't disconnect from the router after it receives the switch request from the new voted root. (root switch happens by invoking esp_mesh_waive_root).
7. Fix the routing announce timer is not stopped immediately in a new root if the new root is transformed from non-root.
8. Choose the candidate with less ie.assoc when doing parent switch.
Update send_ttl mainly for server models. When a server model
receives a message, and the status is required to be replied
by the application, we need to set send_ttl to the msg context.
If send_ttl is not updated in btc, and the applcation does not
set the TTL either, then the status will be replied with TTL=0,
which may cause the client side (e.g. the phone App) failed to
receive the status.
