I want the sx1262 in standby mode to wake up the esp32 via the IRQ pin

[weekroom]

1、Regardless of whether the esp32 is in deep or light sleep, the sx1262 can normally receive data and wake up the device when it is set to accept

void sx1262_deepSleep() {
printf("LoRa Starting to sleep ... \n");
Lcd.sleep();
rtc_gpio_set_direction((gpio_num_t)LORA_IRQ_PIN, RTC_GPIO_MODE_INPUT_ONLY);
rtc_gpio_pulldown_en((gpio_num_t)LORA_IRQ_PIN);
esp_sleep_enable_ext1_wakeup(1ULL << LORA_IRQ_PIN, ESP_EXT1_WAKEUP_ANY_HIGH); // Set to high wakeup
//deep sleep mode
esp_deep_sleep_start();
}
2、If you add radio.standy(), or radio.standby(Module::MODE_RX, true); Power consumption can indeed be reduced, but the IRQ pin cannot be interrupted properly to wake up the esp32
void sx1262_deepSleep() {
printf("LoRa Starting to sleep ... \n");
Lcd.sleep();
radio.standy();
//radio.standby(Module::MODE_RX, true)
rtc_gpio_set_direction((gpio_num_t)LORA_IRQ_PIN, RTC_GPIO_MODE_INPUT_ONLY);
rtc_gpio_pulldown_en((gpio_num_t)LORA_IRQ_PIN);
esp_sleep_enable_ext1_wakeup(1ULL << LORA_IRQ_PIN, ESP_EXT1_WAKEUP_ANY_HIGH); // Set to high wakeup
// deep sleep mode
esp_deep_sleep_start();
}

I don't understand what you're trying to do. In standby mode, the SX126x does not receive any data.

radio.standby(Module::MODE_RX, true);

I don't know what gave you the impression something like this was valid - you are mixing together RF switch modes with SX126x standby modes. See the documentation for SX126x::standby.

I want to reduce the power consumption, when the sx1262 receives data sent by other devices in lora, the IRQ pin is high. This triggers the esp32 wake up
But when I set the sx1262 to standby mode, I can't receive data normally, can only the sx1262 trigger IRQ normally when it is in receive mode

[jgromes]

Like I wrote above, in standby mode SX126x cannot receive anything. That's why the receive mode is called a receive mode, seems pretty self-explanatory. The only way to reduce consumption there is to use startReceiveDutyCycle, where the device periodically cycles between Rx and standby. However, it's up to you to ensure you configure it correctly so that you don't miss any messages. Again, see the documentation, it's all in there.

Thank you very much for your help, using startReceiveDutyCycle function to achieve the function I want, thanks again

I found in the testing process, I set up radio. StartReceiveDutyCycle (50000600, 000); Later let esp32 into sleep, then I found sx1262 will work in the receive mode after a period of time (two to three minutes) into the radio. StartReceiveDutyCycle (50000600 000) that a set of cycles, is there any way to make its directly into this one cycle

No, and the startup time of the ESP32 from deep sleep means there will be gaps. Use an MCU that can wake almost instantly from sleep - SAMD, STM32 etc
