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.
1. resend eb which are pending in g_ic.tx_buf due to channel switch.
2. add lock for mgmg/xon/bcast to protect send from user flush.
3. softap: add check if secondary offset is correct when start softap.
4. softap: in inactive timer handler, add check if child bss is removed to avoid removing it again.
5. disable A-MPDU for non-root.
6. fix reusing a freed eb.
7. fix when node becomes root, it does not record assoc value to nvs.
8. discard unnecessary forwarded group packets.
9. fix toDS state is not updated in time.
10. fix s_sta_cnx_times is not cleared when deinit causes root sends ADD annoucement.
11. root: increase beacon timeout time from 6 seconds to 15 seconds to delay initiation of reconnection.
12. add esp_mesh_get_tsf_time to return TSF time.
13. send the whole routing table multi-times.
14. clear candidate settings if not receive candidate beacon within 8 seconds.
1. detect and fix root conflicts when router BSSID is not set.
2. when root can not connect to the router due to NO_MORE_STAS(reason code:5), root will stop re-connection and perform MESH_NWK_LOOK_FOR_NETWORK.
3. wifi: fix the disconnection caused by receiving a deauth frame from non-parent node during scanning.
4. fix routing table redundant issue.
5. modify the max routes limitation from 300 to 1000.
6. wifi: fix ap does not deauth sta which has not completed the 4-way handshake.
1. when no parent is found, send probe request via broadcast.
2. fix memory leak caused by the remove announcement being sent is not released when esp_mesh_stop() is called.
3. fix modify IE encrypt after mesh is started.
4. ignore esp_mesh_connect() if mesh automatic reconnection is enabled.
5. fix reason is cleared before vote is done.
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.
1. fix failture of mesh stop caused by block-sending.
2. fix when FIXED_ROOT is set, 2nd layer devices can not receive mesh event ESP_ERR_MESH_NO_PARENT_FOUND.
3. fix when FIXED_ROOT is set and the root turns off mesh function, 2nd layer devices do not look for new parents.
4. add APIs esp_mesh_disconnect() and esp_mesh_connect().
5. disconnect from parent/router when the DSSS channel in received beacon is different from the home channel.
6. remove nvs task to release 3k bytes memory.
1. fix ap_loss that occurs when the parent turns off the mesh function and becomes a normal WiFi with a different SSID.
2. add an event MESH_EVENT_NETWORK_STATE that contains information about whether there is a root in the current network.
3. modify the mechanism of mesh IE update.
4. fix a problem in the process of re-voting to select the root, the device that does not meet the conditions of being a root votes for itself.
5. fix an issue that occurs in esp_mesh_recv_toDS() when stopping the mesh.
6. when the user specifies a parent for the device, the device will set the authmode and password of its AP mode to the same value as the specified parent.
7. add two disconnected reason codes MESH_REASON_EMPTY_PASSWORD and MESH_REASON_PARENT_UNENCRYPTED.
1. suppport mesh type, mesh ID, router and IE crypt func&key at any time after mesh is initalized.
2. support modify parent at any time after mesh is configured.
3. modify manual networking example.
4. update header file.
5. fix issues in root conflicts handling.
6. add max length of beacon to menuconfig.
7. fix issue when received a beacon without DSSS.
The following commit rewrites the ESP-MESH docs. This commit includes
new diagrams and a structure approach to the mesh docs. Some mesh api references
have also been modified.
1. new APIs: esp_mesh_get_subnet_nodes_num() and esp_mesh_get_subnet_nodes_list().
2. fix hard to find the parent during connect.
3. disable Wi-Fi channel switch function.
4. fix a typo of MESH_EVENT_NO_PARENT_FOUND.
1. modify parent switch mechanism.
2. fix non-root doesn't clear the layer value in nvs.
3. fix retransmit the remove announcement packets.
4. add API esp_mesh_flush_upstream_packets().
5. automatically adjust passsive scan time based on the change of beacon interval.
1. add mesh_assoc_t to esp_mesh_internal.h file.
2. rename "node" to "device" in esp_mesh.h.
3. add MESH_EVENT_SCAN_DONE event.
4. add APIs esp_mesh_scan_get_ap_record() and esp_mesh_scan_get_ap_ie_len() to get scan results.
5. modify API esp_mesh_set_self_organized() by adding parameter "select_parent".
6. modify API esp_mesh_set_parent() by adding parameter "parent_mesh_id"
7. add manual networking example.
