Hello,
I am new in Wifiprogramming. I have an issue that I cannot unterstand. I have to Unos with a connected nRF24L01, using the MIRF Libary.
My Problem is that the connection is working and the Server Shows a connection result, but it works usally only 5 to 15 times and then the connection is impossible. If I restart the server all fine up to the disconnection. The Client has no effect if I restart them.
Here is my code:
Server:
/**
* An Mirf example which copies back the data it recives.
*
* Pins:
* Hardware SPI:
* MISO -> 12
* MOSI -> 11
* SCK -> 13
*
* Configurable:
* CE -> 8
* CSN -> 7
*
*/
#include <SPI.h>
#include <Mirf.h>
#include <nRF24L01.h>
#include <MirfHardwareSpiDriver.h>
void setup(){
Serial.begin(9600);
/*
* Set the SPI Driver.
*/
Mirf.spi = &MirfHardwareSpi;
/*
* Setup pins / SPI.
*/
Mirf.init();
/*
* Configure reciving address.
*/
Mirf.setRADDR((byte *)"serv1");
/*
* Set the payload length to sizeof(unsigned long) the
* return type of millis().
*
* NB: payload on client and server must be the same.
*/
Mirf.payload = sizeof(unsigned long);
/*
* Write channel and payload config then power up reciver.
*/
Mirf.config();
Serial.println("Listening...");
}
int i = 0;
void loop(){
/*
* A buffer to store the data.
*/
byte data[Mirf.payload];
/*
* If a packet has been recived.
*
* isSending also restores listening mode when it
* transitions from true to false.
*/
if(!Mirf.isSending() && Mirf.dataReady()){
Serial.println("Got packet");
/*
* Get load the packet into the buffer.
*/
Mirf.getData(data);
/*
* Set the send address.
*/
Mirf.setTADDR((byte *)"clie1");
/*
* Send the data back to the client.
*/
Mirf.send(data);
/*
* Wait untill sending has finished
*
* NB: isSending returns the chip to receving after returning true.
*/
Serial.print("Reply sent: ");
Serial.print(i);
i++;
Serial.println();
} else {
Serial.print(".");
}
}
Here is the Client
/**

* MISO -> 12
* MOSI -> 11
* SCK -> 13
*
* Configurable:
