1. Fix the bug that Wi-Fi performance is impacted by BLE starting scan for a while in some scenarios on ESP32-C3.
2. Fix the bug that Wi-Fi performance is impacted when Bluetooth change state for a while in some scenarios on ESP32-C3.
3. Fix the bug that BLE performance is impacted by Wi-Fi scan on ESP32-C3.
4. Fix the bug that Wi-Fi scan fails when BLE is scanning on ESP32-C3.
5. Fix Wi-Fi ACK and CTS rate when low rate is disabled on ESP32-C3.
- Simplify PHY access API
- Move coexist initializing and deinitializing out from PHY API
to Wi-Fi and Bluetooth
- Remove coexist pause and resume for they are no longer needed.
1. Increase delay time before sending NULL1 to enter sleep to
fix compatible problem of some APs.
2. Do not force sending NULL0 if no data tx/rx in previous Wi-Fi
slice.
1. Fix high beacon and broadcast packets loss ratio of WiFi to make
MDNS test pass.
2. Improve stability of WiFi performance with a little
sacrifice of throughput.
3. Improve BLE advertising and connection performance with dynamic
priority. It sacrifices a little WiFi throughput, but achieves balance
between WiFi and Bluetooth.
1. Softap support multicast and broadcast saving and flushing
when the associated stations enable IEEE80211 legacy power
save(which is called modem sleep in ESP32).
2. Improve the frame saving and flushing mechanism of softap power
save.
Due to a hardware limitation in ESP32, the first four bytes of some
CSI data is invalid, not the last four bytes.
Correct a mistake of CSI sub-carrier index in documentation.
state and reduce force receiving broadcast data time
1. If receiving beacon which indicates that there is no data buffered,
do not force to receive WiFi data.
2. If receiving beacon which indicates that there is broadcast data
buffered, reduce the time to force receiving broadcast data.
Hostname option has been removed from dhcp discover since IDFv3.2.
But it remains in dhcp request due to which ESP32 can not get IPv4 address
from some APs. Re-add hostname option to dhcp discover to solve this issue.
Previously, esp-touch only supports multicast packets which are
transmitted from cellphone. But for most dual frequency routers
whose SSIDs of 5G and 2.4G are the same, broadcast packets are
forwarded from 5G interface to 2.4G interface while multicast
packets are not. In order to make esp-touch work when cellphone
connects to 5G interface of these routers, esp-touch is improved
to support both multicast and broadcast packets. Meanwhile, new
APP which is compiled with Andriod or IOS library(>= v0.3.6.2)
must be used in this situation. Note that for some routers,
broadcast and multicast packets are forwarded from 5G interface
to 2.4G interface only when another WiFi device is connected to
2.4G interface of the router. Old APP which is compiled with
Android or IOS library(< v0.3.6.2) also works with this improvement
when cellphone connects to 2.4G interface of the router.
The Android and IOS library of new esp-touch APP is now available
on Github.

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. 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.
1. remove rc when ap not found
closes issue: https://github.com/espressif/esp-idf/issues/1797
2. allocate mimo packet to internal memory
3. use FRC2 timer instead of WDEV_NOW() for modem sleep to calculate
TBTT time.
It fixes the bug that TBTT will be incorrect if beacon is lost.

When tcp write/connect is running, close socket request will abort
it and continue to delete netconn and close tcp. Do not immediately
return after aborting tcp write/connect. Otherwise, tcp close
requeset will block and tcp write/connect will crash.
1. Add a hide API for station to receive and process probe request
frame.
2. Fix an issue that wifi/bt coexistence crashes in PSRAM version.
3. Fix an issue that the API for clearing vendor ie can not work.
4. Fix an issue that wifi stop and reboot leads watchdog.
1. V366, fix a problem which initialize current can reach 800mA.
2. V365, fix a problem for pll_cap tracking in Coexist (BT & WIFI)
mode. The problem will make Coexist (BT & WIFI) WIFI AP mode TX
Fail in high temperature(>70).
3. V364, fix a bug of BT and Wifi coexist (hung in function of
force_wifi_mode())
get IP address after connecting to the softap.
Now the default netif is station in station+softap mode. The UDP pcb of
DHCP server is binded to IP 0.0.0.0. When other device connects to softap, the
DHCP offer will be sent by softap.But because the destination IP of DHCP offer
is broadcast IP and the source IP of it is 0.0.0.0, it will be sent from default
netif, that is station interface. Other device can not receive the DHCP offer
sent from station interface. As a result, other device can not get IP address.
The resolution is that bind UDP pcb to the IP address of softap. So, the source
IP of DHCP offer is that of softap. DHCP offer can be sent from softap interface
by source IP route method.
1. add adc2 coexistence
2. change NOW() to WDEV_NOW()
3. call ets_timer_done() before calling ets_timer_setfn()
4. fix the bug that api lock is not unlocked when call esp_wifi_stop()
twice
5. more hmac tx buffer limit from 32 to 64.
ESPNOW is a kind of WiFi communication bettween WiFi devices, no
matter they are connected to each other or not. Once two WiFi
devices are paired, they can send data to or receive data from
each other. The data is transmitted in action frame which can
be encrypted with CCMP method. ESPNOW also support mutilcast frame
transmitting.
All peripheral clocks are default enabled after chip is powered on.
When CPU starts, if reset reason is CPU reset, disable those clocks
that are not enabled before reset. Otherwise, disable all those
useless clocks.
These peripheral clocks must be enabled when the peripherals are
initialized and disabled when they are deinitialized.
If destination IP address of the packet is broadcast address, firstly compare
source IP address with the that of each network interface. If it matches,
packet is forwarded from the interface.
1. Store the information of AP(ssid, password, bssid, channel, etc)
into nvs when station connects to AP successfully. If station
connects to the same AP next time, it will scan the stored channel of the AP
first.
2. Add a parameter of channel for scanning before connecting to AP.
If it is set to 1~13, station will scan starting from the channel.
If the channel of AP is unknown, set it to 0.
There are some RODATAs of libphy.a that are called in ISR. So need
to put them into DRAM to avoid access them when R/W SPI flash. Due
to the RODATAs which are called in ISR haven't been picked out to
put into DRAM, put all of the RODATA of libphy.a into DRAM. This
will be optimized in the future.
Base MAC address can be stored in default manufacture-defined or customer
pre-defined place in EFUSE and other place e.g. flash or EEPROM.
If choose to use base MAC address which is stored in other place, please
call esp_base_mac_addr_set_external() before initializing WiFi/BT/Ehternet.
If static tx buffer is selected, WiFi tx buffers are allocated when WiFi is initialized and released
when WiFi is de-initialized. If dynamic tx buffer is selected, WiFi tx buffer is allocated when tx
data is delivered from LWIP to WiFi and released when tx data is sent out by WiFi.
The size of each static tx buffers is fixed to about 1.6KB and the size of dynamic tx buffers is
depend on the length of the data delivered from LWIP.
If PSRAM is enabled, "STATIC" should be selected to guarantee enough WiFi tx buffers.
If PSRAM is disabled, "DYNAMIC" should be selected to improve the utilization of RAM.
