Description

Crowtail - LoRa RA-08H uses the Ra-08H (ASR6601) module, which has ultra long distance spread spectrum communication. Its chip ASR6601 is a general-purpose LPWAN wireless communication SoC integrated with RF transceiver, modem and a 32-bit RISC MCU. The Ra-08H module supports LoRa modulation and traditional (G) FSK modulation under the LPWAN use case; The transmitter also supports BPSK modulation and (G) MSK modulation.
The Ra-08H module provides ultra long range and ultra-low power consumption communication for LPWAN applications, and can be widely used in intelligent instruments, supply chain and logistics, home building automation, security systems, remote irrigation systems and other scenarios.

STEP3 Open the program in the Arduino IDE
#include <SoftwareSerial.h> 
// Pin2接LORA的TXD
// Pin3接LORA的RXD
SoftwareSerial LORA(2, 3); 
char val;
 
void setup() {
  Serial.begin(9600); 
  Serial.println("LORA is ready!");
  LORA.begin(9600);
}
 
void loop() {
  if (Serial.available()) {
    val = Serial.read();
    LORA.print(val);
    delay(10);
  }
 
  if (LORA.available()) {
    val = LORA.read();
    Serial.print(val);
    delay(10);
  }
}
STEP4 Click the Upload.png to upload the code to the Crowduino board
STEP5 Open the AT command description of Ra-08H, find the relevant command, open the serial port monitor, and input the command into the serial port monitor, for example, enter [AT+CGSN?] Command, click Send, and the reply code will be received:
+CGSN=1E612A8482213201
OK
