Rhf76-052am - getting it working with OTAA

This timeout parameter works on my Node :slight_smile:

Anyone trying to get these modules working with the AU915 band and OTAA must update to firmware version V2.1.19 (25 May 2018) This can be downloaded from RisingHF’s wiki page once you have a login.

If you don’t upgrade, you will be able to send a join request to a gateway, the gateway will acknowledge with a join accept, but the RHF76-052 will never receive the join accept and fail. ABP will work if you never need to use the downlink.

There was a AU915 downlink issue fixed in V2.1.17 and also a DR6 issue fixed in V2.1.19.

As we use sub-band 2 in Australia, simply delete channels that are not used with AT+CH=‘Channel to Del’, 0.
In most cases this is 0 to 7, 16 to 64, 66 to 71. It should then work first go!

Could you post the firmware file somewhere for people without RisingHF wiki login?

Is there a changelog from 2.1.16 to this one?

Thanks!

Hi !

Is it possible to share the firmware release 2.1.19 or later I am stuck with 2.1.15 and having issues in joining to network, Thanks in advance

This code I customized and I am sharing works perfectly for me.
I’m using version 2.1.16
I use the default libraries of seeeduino.

#include <TheThingsNetwork.h>
#include <LoRaWan.h>
#include “DHT.h”

#define DHTPIN 8
#define DHTTYPE DHT22

DHT dht(DHTPIN, DHTTYPE);

unsigned char data[4];

char buffer[256];

void setup(void)
{
dht.begin();

SerialUSB.begin(115200);
while(!SerialUSB);

lora.init();
memset(buffer, 0, 256);
lora.getVersion(buffer, 256, 1);
SerialUSB.print(buffer); 

memset(buffer, 0, 256);
lora.getId(buffer, 256, 1);
SerialUSB.print(buffer);
lora.setId("XXXXXXXX", "XXXXXXXXXXX","XXXXXXXXXXX" );        
lora.setKey(NULL, NULL, "XXXXXXXXXXXXXXXXXXXXXXXXXXXX");

lora.setDeciveMode(LWOTAA);    

lora.setDataRate(DR5, EU868);

lora.setAdaptiveDataRate(true);    

lora.setChannel(0, 868.1);
lora.setChannel(1, 868.3);
lora.setChannel(2, 868.5);
lora.setChannel(3, 867.1);
lora.setChannel(4, 867.3);
lora.setChannel(5, 867.5);
lora.setChannel(6, 867.7);

lora.setReceiceWindowFirst(1, 868.3);
lora.setReceiceWindowSecond(869.525, DR0);

lora.setPower(14);

while(!lora.setOTAAJoin(JOIN));

}

void loop(void)
{

bool result = false;
delay(2000);
SerialUSB.println("-- LOOP");

uint32_t humidity = dht.readHumidity(false) * 100;

// float t = dht.readTemperature(false);
uint32_t temperature = dht.readTemperature(false) * 100;

byte payload[4];

payload[0] = highByte(temperature);
payload[1] = lowByte(temperature);
payload[2] = highByte(humidity);
payload[3] = lowByte(humidity);

SerialUSB.print("Temperatura: ");
SerialUSB.println(temperature);
SerialUSB.print("Umidade: ");
SerialUSB.println(humidity);

// SerialUSB.print("Temperatura: " + String(temperature));

// SerialUSB.print("Umidade: " + String(humidity));

//byte payload[4];
//data[0] = highByte(t);
//data[0] = lowByte(t);
//data[2] = highByte(h);
// data[1] = lowByte(h);

// data[1] = h;
// data[2] = t;

result = lora.transferPacket(payload, 4, 10);
//result = lora.transferPacket("Marcelo Balisteri!", 10);

if(result)
{
    short length;
    short rssi;
    
    memset(buffer, 0, 256);
    length = lora.receivePacket(buffer, 256, &rssi);
    
    if(length)
    {
        
        SerialUSB.print("Length is: ");
        SerialUSB.println(length);
        SerialUSB.print("RSSI is: ");
        SerialUSB.println(rssi);
        SerialUSB.print("Data is: ");
        for(unsigned char i = 0; i < length; i ++)
        {
            
            SerialUSB.print("0x");
            SerialUSB.print(buffer[i], HEX);
            SerialUSB.print(" ");
        }
        SerialUSB.println();
        
    }
}
delay(5000);

}

This is the TTN decoder Temp and Hum


// Decodificação do payload no tttn

function Decoder(bytes, port) {
var humidity = (bytes[0]<< 8) | bytes[1];
var temperature = (bytes[2] <<8) | bytes[3];

return {
humidity: Umidade,
temperature: Temperatura
}
}
