Transmitter_Receiver using the RYLR LoRa tranceiver module

Projects Programming

Hi everyone !
I need help find a working program defining a Lora Transmitter and a LoRa receiver using (RYRL896) and connected Arduino Uno.

It could be software Serial or hardware Serial.

to send DHT11 value.

Lora.begin is failing

void setup() { 
  dht.begin(); 
  Serial.begin(9600);
  while (!Serial);
  Serial.println("LoRa Sender test");
  //initilize the LoRa radio on the module
  LoRa.begin(915000000);
  if (!LoRa.begin(915E6)) {     
  Serial.println("Starting LoRa failed!");
  while (1);
  }
}

If your actually using an RYLR896 then thats a UART front ended LoRa module, and you appear to be trying to use a LoRa library for the normal SPI based modules, so that library wont work.

thanks!

What are the conditions for using #include <lora.h> ?

lora.begin(915e6) is never working just like that

Read post #4 again.

Have you checked that the lora.h library you are trying to use will work with your module ?

It says that <lora.h> is is compatible with the SX1276 engine, which is what is featured in the RYLR896.

I tested the modules, they work when connected via UART to TLL conversion. they can send data to each other.

My problem is that I cannot find any program (TX /RX) that can work to send the sensor data from one node to the other.

No, No, No.

Study the lora.h documentation again and post #4 yet again.

The (normal) lora.h library expects an SPI hardware interface.

Your RYLR896 does not have an SPI interface, it has a UART interface.

Probably true, there are very few worked examples for those UART based supposed LoRa modules.

There are however gazillions of examples and a fair number of libraries for the normal SPI based modules.

11

Yes, that s true.
