esp_wifi_80211_tx sometimes not working when waking up from esp_light_sleep

[ludoplt]

Hardware:

Board: ESP32 WROOM IDE name: Arduino

Description:

I want to use esp_wifi_80211_tx after an esp_light_sleep period. Sometimes, after wakeup, esp_wifi_80211_tx don't want to work... and sometimes it work at the next wake up ! Strange and problematic for my case..

Any idea ?

#include <esp_wifi.h>
#include <esp_bt.h>
#include <esp_deep_sleep.h>
#include <WiFi.h>
#include <esp_spi_flash.h>

wifi_init_config_t wifiInitializationConfig = WIFI_INIT_CONFIG_DEFAULT();

void setup() {
  esp_wifi_init(&wifiInitializationConfig);
  esp_wifi_start();
  esp_wifi_set_promiscuous(true);
  esp_wifi_set_channel(2, WIFI_SECOND_CHAN_NONE);
  btStop();
  esp_bt_controller_disable();
  setCpuFrequencyMhz(80);
}

void loop() {
  esp_wifi_start();
  esp_wifi_set_promiscuous(true);
  esp_wifi_set_channel(2, WIFI_SECOND_CHAN_NONE);

  esp_wifi_80211_tx(WIFI_IF_STA, packet, sizeof(packet), false);
  delay(500);
  esp_sleep_enable_timer_wakeup(500 * 1000);
  esp_light_sleep_start();
}

I have the same behavior with a TTGO-TDisplay board, I was trying to improve consumption in my Air quality device, for this reason I implemented a light suspend for keep the display on into each screen refresh, but after some hours the board go freezing, the only method for turn on it, is with reset button. I don't have any log because the output its fine, don't happened anything before it freezing.

My code:

//! Long time delay, it is recommended to use shallow sleep
void espShallowSleep(int ms) {
    esp_sleep_enable_timer_wakeup(ms * 1000);
    esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_PERIPH, ESP_PD_OPTION_ON);
    esp_light_sleep_start();
}

void loop() {
    bmeLoop();                      // the BME680 sensor loop.
    pmsensorLoop(bleIsConnected()); // if phone is connected, the turnon
                                    // sensor interval is minor.
    wifiLoop();                     // check wifi or reconnect it.
    bleLoop();                      // notify data to phone or BLE device
    apiLoop();                      // CanAir.io API publication.
    influxDbLoop();                 // influxDB publication.
    otaLoop();                      // check for firmware updates.
    guiLoop();                      // gui ttf refresh methods.

    // save battery after phone disconnected:
    if (!bleIsConnected()) espShallowSleep(5000); // <== this line reproduce the behaivor 
}

when I comment the last line, the device works fine, many hours without any issue.
