Hi Renzo, your LIB works perfect, many thanks to you!
I have a question that may not be directly related to the library, but I can’t find a solution for it.
If I send more than 4 messages (regardless of length) in a row (transparentTransmission) then the transmission module goes down and you have to reboot it.
Is this perhaps a Lora rule? … if so, can this be switched off?
Thanks for your work, Georg
Hi Georg,
no, I think there is a bug on your code.
Can you post the source code.
Bye Renzo
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
Try to put a better external 5v power supply to the LoRa device.
If in your code there isn’t a memory leak there isn’t a reason for that.
