You got the basic usage of inheritance and virtual methods right. There is one nasty bug though - you forgot to make your destructor virtual in the base class (MyComms). This means that if you ever destroyed an object through a pointer to the base class, the correct destructor would not be called ...

Make sure you mark your capture callback with IRAM_ATTR. Made a huge difference for me (went from 50-300 to 1500-2000 packets per second)

To improve the capture speed try this:

1. Remove your printf calls from the sniffer callback. The callback has to finish as soon as possible.
2. Mark the function as IRAM_ATTR. This resulted in a 10x rate improvement for me:


IRAM_ATTR void packet_received_cb(void* buf, wifi_promiscuous_pkt_type ...

Do this:

led.h

#ifndef LED_H
#define LED_H

#include <stdint.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "driver/gpio.h"

class LED
{
public:
LED();

private:
static void staticBlinkLedTask(void *pvParameter);
void blinkLedTask();

...
};

#endif //LED_H


led.cpp ...

Pls use a mangled name for the internal macro variable rc.
That's because in C/C++ this statement actually compiles:

int a = a;

It results in variable a being uninitialized essentially.
So with your macro, this code would have unexpected results:

int rc = 7;
ESP_ERROR_CHECK(initialize_remote ...

No idea about the extra params. I tried to play with them but got no meaningful info.
Wireshark told me the modulation was CCK. 1 & 2 Mbps 802.11B should be DSSS indeed but as far as I read, CCK and DSSS are very similar. Both are spread spectrum, just the coding sequence is different - but I don't ...

You should find it in libpp.a. I'm using the latest arduino esp32 idf.

Regarding the "E (6348579) wifi: out of memory!" error when injecting, you can silence it using esp_log_level_set("*", ESP_LOG_NONE); so that it doesn't kill your data rate. I didn't find any way to get notified when the packet ...

Found a way to set the fixed rate.
There is a github issue about this with some barely documented code:
//https://github.com/espressif/esp-idf/issues/833

The first 15 rates are identical to the esp8266 when using the wifi_set_user_fixed_rate(FIXED_RATE_MASK_ALL, x) function.

I checked every rate ...

Not specifically hardware related - give access to the low-level wifi functionality:
- Packet injection with send callbacks (like the esp8266)
- Monitor mode with hardware packet filters (MAC bases)
- Manual rate & modulation & channel selection

Lots of ppl are interested in this for long range HD ...

Hi Samurai,

Did you find any answers? I'm especially interested in a callback whenever the packet was sent with the esp_wifi_80211_tx function. Without it it's impossible to schedule new packets...

Regarding your rate problem, there is this comment here:
Please note that the sniffer has a great ...
