Using HSPI ESP32 for LoRa

[Ddh012345dhD]

i configure my lora set on HSPI on ESP32 and use LoRaDuplexCallback function but only transmit but not receive data from node. Someone help me please! My code:

#define lora_sck 14
#define lora_miso 12
#define lora_mosi 13
#define lora_cs 15
#define lora_rst 4
#define lora_irq 16
#define nodeFourth_addr 0x04
#define fre 433E6
SPIClass  hspi(HSPI) ;
LoRaClass LoRa2;
void lora_Config();
void sendRequest(byte addr_destination, String message);
void onReceive1(int packetSize);
void lora_Config()
{
 // pinMode(lora_cs, OUTPUT); 
 hspi.begin(lora_sck, lora_miso, lora_mosi);
 LoRa2.setSPI(hspi);
 LoRa2.setPins(lora_cs, lora_rst, lora_irq);
  // override the default CS, reset, and IRQ pins (optional)
  if (!LoRa2.begin(fre)) {             // initialize ratio at 915 MHz
    Serial.println("LoRa init failed. Check your connections.");
    delay(5000);
    ESP.restart();
  }
  LoRa2.setTxPower(20);    
  LoRa2.onReceive(onReceive1);
  LoRa2.receive();
  LoRa2.enableCrc();
  Serial.println("LoRa init succeeded.");
}
void sendRequest(byte addr_destination, String message)
{
  uint8_t data_send[3]; 
  data_send[0] = addr_destination;
  data_send[1] = gattway_addr;
  data_send[2] = message.length();
  uint8_t crc=crc8(data_send, 3);
  LoRa2.beginPacket();
  LoRa2.write(data_send[0]);
  LoRa2.write(data_send[1]);
  LoRa2.write(data_send[2]);
  LoRa2.write(crc);
  LoRa2.print(message);
  LoRa2.endPacket();
 // state_request=false;
}
void onReceive1(int packetSize)
{
   packetSize = LoRa2.parsePacket();
   byte data_rec[4];
   String LoRaData="";
   if (packetSize == 0) return; 
   data_rec[0]=LoRa2.read(); //Serial.println(data_rec[0]);//addr gatt
   data_rec[1]=LoRa2.read();//Serial.println(data_rec[1]);// addr node
   data_rec[2]=LoRa2.read(); //Serial.println(data_rec[2]);
   data_rec[3]=LoRa2.read();// Serial.println(data_rec[2]);
   while (LoRa2.available()) LoRaData = LoRa2.readString(); Serial.println(LoRaData);        
   if ((data_rec[0] != gattway_addr)|| (data_rec[1]!= destination_addr )){ Serial.println("not for me."); return ;}                         
   if(data_rec[3] != crc8(data_rec, 3)){ Serial.println("crc faile"); return;}
   if(LoRaData.length() != data_rec[2]){ Serial.println("data length faile"); return;}
   decode_data(data_rec[1],LoRaData);
}
void setup() {
 Serial.begin(115200);
 lora_Config();
 xTaskCreate(task_lora_data,"lora",5000,NULL,0,&TaskHandle_1);
}
unsigned long t1=0;

     {
      state_request=false;
      destination_addr =nodeFourth_addr;
      cmd =cmdR;
      sendRequest(destination_addr,cmd);
      LoRa2.receive();
      if(state_request==false) {state_request =true;i+=1;if(i>3) i =0;}
      }     
   }
   vTaskDelay(10);
  }
}

Hello, Is this still a problem?

I am also using ESPs HSPI and it is working for me.

I think you should remove this line: hspi.begin(lora_sck, lora_miso, lora_mosi);

Here is how I use it:

SPIClass hspi = NULL;

void setup() {

  hspi = SPIClass(HSPI);
  LoRa.setSPI(hspi);

  LoRa.setPins(RF_CS, RF_RST, RF_IRQ);

  ...
