Thank you for the answer.
I am not sure if I have expressed myself correctly and that I understand it correctly.
I actually do not want to activate wakeup on lora but just react very quickly to a received message … (or does an interrupt only work together with wakeup?).
My problem is:
In my application I have a very long program under void loop() and within this program the request if (e220ttl.available()>1) … due to the long program the processing of LoraReceive is sometimes very late.
Sorry for this further question, I just want to understand it before I rebuild my program and I’m not sure if I’m affecting anything else with wakeup

Hi Renzo,
thank you very much for the quick reply.
here the code for Lora send. The amount of data is about 15 characters.

// ************** LoRa-Send *****************
void LoraSend(int _counter, unsigned long _wert_millis) {

String temp; // Sendedaten zusammenbauen
temp = “Nr: ” + String(_counter) + ” Millis: ” + String(_wert_millis);

// Send message
//e220ttl.sendMessage(temp);
ResponseStatus rs = e220ttl.sendMessage(temp);
// Check If there is some problem of succesfully send
Serial.println(rs.getResponseDescription());
}
// ************** END LoRa-Send *****************

At the sender I always get the answer “successful”, even when sending more than 4 telegrams.
the first 4 telegrams arrive also without problems at the receiver, then unfortunately nothing more comes.
After that, no reset of the send-ESP32 helps, but only removing the voltage of the send-Ebyte220 – only then another 4 telegrams come through again.
Many thanks in advance for your help,
Georg
