[GitHub] [nuttx] tmedicci opened a new issue, #8061: ESP32-C3 Wi-Fi miss-behavior depending on the Access Point
tmedicci opened a new issue, #8061:
URL: https://github.com/apache/nuttx/issues/8061
**The Behavior**
After the implementation of the IOB buffer handling directly from the Wi-Fi driver (https://github.com/apache/nuttx/pull/7817/), it seems that there exist problems while handling small packets and ping requests do not return successfully.
It's worth noting, however, that this problem is depending on the connected access point. Android Hotspots and TP-Link (OpenWrt-enabled) routers usually fail. The Sagemcom F@ST 3895 router ping response is higher and, then, it doesn't fail.
**Steps to reproduce**
It's possible to see the behavior on master [67ccee2c4f581c3c772592f3393e437cf11af186](https://github.com/apache/nuttx/commit/67ccee2c4f581c3c772592f3393e437cf11af186) since the commit [61563d6004fe92ae50d567bc4f81c81f60d8c757](https://github.com/apache/nuttx/commit/61563d6004fe92ae50d567bc4f81c81f60d8c757)
`
make -j distclean && ./tools/configure.sh esp32c3-devkit:wapi && make menuconfig && make -j bootloader && make -j flash ESPTOOL_PORT=/dev/ttyUSB0 ESPTOOL_BINDIR=./ && minicom -D /dev/ttyUSB0
`
In order to check the possible problem regarding small packets + IOB implementation, just apply the following patch and turn on the debug logs for the network:
```
