Backport following WiFi fixes to v3.1:
1. Fix AMPDU RX sequence compitability bug
2. Optimize scan capability in all channel scan
3. Fix some modem sleep bugs
4. Update API to set CSI channel filter and HT_LTF data generating
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.
Some APs transmit AMPDU and MPDU by turns. Moreover, the sequence
numbers of AMPDU and MPDU are out of order, e.g. MPDU(1253) -
AMPDU(1251, 1252) - MPDU(1254) - AMPDU(1255, 1256). In order to
receive both AMPDU and MPDU in order, MPDU must be reordered with
AMPDU.
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.
Fix following WiFi bugs:
1. Shouldn't scan when connect
2. Check beacon length in modem sleep
3. Fix the bug that AP may deauth wrong station when inactivity timer expires
4. Fix the bug that WiFi assert the system when receiving empty MCS in association response frame
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.
Backport following bug fixes to v3.1:
1. Bug fix of may connect to wrong AP in all channel scan
2. Station state machine change and fix ap loss
3. Add compatible to ccmp encryption
4. Update libphy.a to v3960:
4.1 Decrease phy_init time from 900us to 347us in sleep wakeup
4.2 Fix RX STBC initialization
4.3 Modify set_chan function to fix interrupt watchdog issue
5. Fix several wpa2 enterprise issues
5.1 Fix heap corrupted bug
5.2 Fix memory leak bug
5.3 Make wpa2 enterprise thread-safe
Closes https://github.com/espressif/esp-idf/issues/1569
6. Bugfix of coex wifi pm
This change adds a check for compatibility between the nvs version
found on nvs flash and the one assumed by running code during nvs
initialization. Any mismatch is reported to the user using new error
code ESP_ERR_NVS_NEW_VERSION_FOUND.
Since 94250e42a0, UART output is suspended when entering sleep mode
(deep or light sleep). This makes sense for light sleep, where sleep
normally takes small amount of time, and flushing the UART would add
a lot of latency. But this breaks existing behaviour for deep sleep,
where UART output was previously sent out before entering sleep mode.
Closes https://github.com/espressif/esp-idf/issues/2145
1. Move channel to the first row of the table.
2. Remove the condition of HT20/HT40 for they are determined by
secondary channel.
3. Clean up the CSI table.
INTERRUPT and CCOUNT registers will change outside of program control.
Making the inline assembly used to read these registers volatile
indicates this fact to the compiler.
Fixes https://github.com/espressif/esp-idf/issues/2127
1. fix BLE connection missing in coex mode
2. modify other parameters to make coex priority more reasonable
3. fix modem sleep procedure trap cause Wifi disable RF when BT is
working. Such cause that BR/EDR is difficult to be connected, BLE
connection stability decrease and so on.
4. modify BR/EDR coexist duration to imrove BR/EDR connect success
ratio.
5. Due to the hardware coexist bug, BLE scan interval/window should
be less than 0x100(about 160ms). Therefore, it will cause BLE cannot
scan any advertising packet while WiFi have higher priority
behaviour(such like RX beacon, scan, TX/RX VO packets and etc.).
1. add APIs to set/get announce interval values.
2. add API to enable/disable the min rate to 6Mbps for data packages.
3. add APIs to set/get RSSI threshold values.
4. fix ap_loss.
