fdcavalcanti opened a new pull request, #17008:
URL: https://github.com/apache/nuttx/pull/17008
## Summary
- boards/xtensa: update board and defconfigs for Wi-Fi on ESP32|S2|S3
Updates the defconfigs and board source to support driver refactor.
- arch/xtensa: refactor Wi-Fi driver for ESP32|S2|S3
Fixes low and inconsistent bandwidth issues. Adds new configuration options
for buffer management. Moves code around to make the implementation cleaner and
easier to debug.
This PR is similar and complements the refactor of Wi-Fi for Espressif
devices as seen on #16921. Please refer to that PR for detailed changes on
architecture level.
## Impact
- Impact on user: Yes, users now have a more stable and higher throughput.
Also improved wapi function support.
- Impact on build: No.
- Impact on hardware: No.
- Impact on documentation: No.
- Impact on security: No.
- Impact on compatibility: No.
## Testing
Tested extensively on ESP32|S2|S3. Test involves wapi function usage, IPERF
test for stability and throughput, DHCP and both operating modes: Wi-Fi station
and AP.
### Building
- ./tools/configure.sh esp32s3-devkit:sta_softap
- make and flash
### Running
Many tests are used for Wi-Fi, so I won't show them all here, but would be
happy to share them if needed.
I´ll share the process for IPERF testing on AP and STA.
IPERF testing example with ESP device running as client:
```
wapi psk wlan0 espmint123 3 3
wapi essid wlan0 Nuttx-IOT 1
renew wlan0
iperf -c 192.168.0.125 -i 3 -t 60
```
For running as IPERF server, use the following instead:
- iperf -s
### Results
Connecting to AP:
```
nsh> wapi psk wlan0 espmint123 3 3
nsh> wapi essid wlan0 Nuttx-IOT 1
nsh> renew wlan0
nsh> ifconfig
wlan0 Link encap:Ethernet HWaddr 58:cf:79:07:51:e8 at RUNNING mtu 1500
inet addr:192.168.0.30 DRaddr:192.168.0.1 Mask:255.255.255.0
wlan1 Link encap:Ethernet HWaddr 58:cf:79:07:51:e9 at DOWN mtu 1500
inet addr:0.0.0.0 DRaddr:0.0.0.0 Mask:0.0.0.0
```
Running IPERF client results in:
```
nsh> iperf -c 192.168.0.125 -i 3 -t 60
IP: 192.168.0.30
mode=tcp-client sip=192.168.0.30:5001,dip=192.168.0.125:5001, interval=3,
