[SOLVED] Heltec ESP32 LoRa Receive Interrupt
Posted: Wed Feb 24, 2021 7:43 pm
Hi,
I’m trying to make a LoRa sender/receiver board.
Therefore the plan is to send some messages whenever I want, but if there is an incoming packet, I want to interrupt the sending-process (for beginning without any sending retries) and receive the incoming packet.
I tried the mix of the Heltec examples “OLED_LoRa_Sender” and “LoRaReceiverInterrupt”, and it works fine until I’m sending and receiving a message at the same time. Then the receive interrupt does not interrupt.
How can I solve that?
Thanks a lot in advance

Code: Select all
void loop(){
if (sendMsg && !receivingMsg) { // sendMsg drives true, if PRG button is pressed receivingMsg drives try in "void onReceive(int packetSize)"
/*
Heltec.display->clear();
Heltec.display->setTextAlignment(TEXT_ALIGN_LEFT);
Heltec.display->setFont(ArialMT_Plain_10);
//Serial.println(WiFi.macAddress());
Heltec.display->drawString(0, 0, "Sending packet: ");
Heltec.display->drawString(0, 15, WiFi.macAddress());
Heltec.display->drawString(100, 15, String(counter));
Heltec.display->display();

LoRa.beginPacket();
LoRa.setTxPower(14,RF_PACONFIG_PASELECT_PABOOST);
LoRa.print("hello ");
LoRa.print(counter);
LoRa.endPacket();
delay(10); // give me time to bring up serial monitor
counter++;
// put the radio into receive mode
LoRa.receive();
sendMsg = false;
}
}
