Hi Sir @beegee I’m currently trying a multinode application, wherein my two RAK4631 will serve as end nodes. And I got still the “Error compiling for board WisBlock Core RAk4631 Board”. I followed your abovementioned advices and it worked for my sample code, but, failed when I tried to my current multinode set up.
Here’s my code:
#include <SPI.h>
#include <RH_RF95.h>
RH_RF95 rf95;
void setup()
{
Serial.begin(9600);
while (!Serial) ; // Wait for serial port to be available
if (!rf95.init())
Serial.println("init failed");
rf95.setFrequency(915.0);
}
void loop()
{
uint8_t buf[RH_RF95_MAX_MESSAGE_LEN];
uint8_t len = sizeof(buf);
if (rf95.waitAvailableTimeout(3000))
{
// Should be a reply message for us now
if (rf95.recv(buf, &len))
{
int dataLength;
String Request = (char*)buf;
if (Request == "G3") {
Serial.println("Slave 3 Got Request from the Master!");
Serial.print("Response to the Master: ");
String data = ("Nice to meet you!");
int dataLength = data.length();dataLength++;
uint8_t total[dataLength]; //variable for data to send
//data.toCharArray(total, dataLength); //change type data from string ke uint8_t
Serial.println(data);
Serial.println();
rf95.send(total, dataLength); //send data
rf95.waitPacketSent();
}
}
}
else
{
Serial.println("No reply, is rf95_server running?");
}
delay(400);
}
Here’s the error I’ve gotten:

Do you have any suggestions that I could try? I’ve been fixing this for 2 days already but I haven’t seen concerns similar to this one in the internet.
Thank you so much.
