The Lora.endPacket() gets stuck during the second pass

[JBravo2323]

Hello Sandeep I added these Serial.println for debugging in the Library: { Serial.println("LoRaClass::endPacket: before writeRegister(REG_OP_MODE, MODE_LONG_RANGE_MODE | MODE_TX);"); // put in TX mode writeRegister(REG_OP_MODE, MODE_LONG_RANGE_MODE | MODE_TX);

Serial.println("LoRaClass::endPacket: before while((readRegister(REG_IRQ_FLAGS) & IRQ_TX_DONE_MASK) == 0);"); // wait for TX done while((readRegister(REG_IRQ_FLAGS) & IRQ_TX_DONE_MASK) == 0);

// clear IRQ's Serial.println("LoRaClass::endPacket before writeRegister(REG_IRQ_FLAGS, IRQ_TX_DONE_MASK);"); writeRegister(REG_IRQ_FLAGS, IRQ_TX_DONE_MASK);

return 1; }

*When I run the program this is what I get: ***

LoRa Sender 7 From the Library Definintion version = 9 Sending packet: 0 LoRaClass::endPacket: before writeRegister(REG_OP_MODE, MODE_LONG_RANGE_MODE | MODE_TX); LoRaClass::endPacket: before while((readRegister(REG_IRQ_FLAGS) & IRQ_TX_DONE_MASK) == 0); LoRaClass::endPacket before writeRegister(REG_IRQ_FLAGS, IRQ_TX_DONE_MASK); Sending packet: 1 LoRaClass::endPacket: before writeRegister(REG_OP_MODE, MODE_LONG_RANGE_MODE | MODE_TX); LoRaClass::endPacket: before while((readRegister(REG_IRQ_FLAGS) & IRQ_TX_DONE_MASK) == 0);

So it appeared it never leaves this while while((readRegister(REG_IRQ_FLAGS) & IRQ_TX_DONE_MASK) == 0); Regards

Hey @JBravo2323,

What sketch are you using? Also, what hardware?

[JBravo2323]

Lora Sender and Lora Receiver are the sketches The hardware is the Adafruit RFM95W LoRa Radio Transceiver Breakout - 868 or 915 MHz Thanks

@JBravo2323 what Arduino board are you connecting to the Adafruit RFM95W LoRa Radio Transceiver Breakout?

Could you please update to the latest release and try to lower the SPI frequency via: https://github.com/sandeepmistry/arduino-LoRa/blob/master/API.md#set-spi-frequency

Try values of: 8e6, 4e6, and 1e6.

Closing this for now due to lack of feedback.

Hey @sandeepmistry

sender code :

include

include

int counter = 0;

void setup() { Serial.begin(9600); while (!Serial);

Serial.println("LoRa Sender");

if (!LoRa.begin(433E6)) { Serial.println("Starting LoRa failed!"); while (1); } LoRa.setSPI(SPI); LoRa.setSPIFrequency(4e6); LoRa.setSpreadingFactor(10); LoRa.setSignalBandwidth(42.5E3); LoRa.crc(); }

void loop() { Serial.print("Sending packet: "); Serial.println(counter);

// send packet LoRa.beginPacket();

LoRa.print("hello "); // Serial.print("hello "); LoRa.print(counter); // Serial.println(counter);

// if(counter==1) LoRa.endPacket(); //Serial.print("asdfgh");

Serial.print("Lora Send: "); Serial.println(counter); counter++;

delay(2000); }

Serial Output : LoRa Sender Sending packet: 0 Lora Send: 0 Sending packet: 1

Problem : I have the same problem. Its not sending packet 1 after sending packet 0 due to some problem in the statement Lora.endPacket();

Kindly help asap. I already tried setting the SPI frequency to 1e6,4e6 and 8e6. It didn't worked. Board used: Arduino Uno Chip used : Ra-01_V1.4
