Hello,

Weeks ago, I started to try interfacing my Arduino Uno r3 with one of my nokia phones (6086 & 6136).
I have been through lot of links, blogs and even this forum.
Here is a short list:

http://www.insidegadgets.com/2013/01/12/how-to-use-nokia-f-bus-to-send-an-sms-message/

This leads me to try many methods. And finally none of them worked out.
All of those methods use FBus.

Here is an exhaustive list of what I tried:
- Nokia RX|TX connected to Arduino TX|RX directly, use of Serial.write and Serial.print, all baud rates tested : NOK
- Nokia RX|TX connected to Arduino pin 2 & 3, use of SoftwareSerial, all baud rates tested : NOK
- Nokia RX|TX connected to Arduino TX|RX directly, Arduino TX signal inverted using a transistor, use of Serial.write, all baud rates tested : NOK
- Nokia RX|TX connected to Arduino pin 2 & 3, use of SoftwareSerial, signal inverted option of SoftwareSerial, all baud rates tested : NOK
- And even trying to send AT command with RX|TX --> TX|RX wiring (why not !): NOK

The only thing that happened is getting a single 0 in the second method if I remeber well.
I learnt a lot, but to be honnest, I think I am going to burn those damn phones...

But if by any chance you have an idea (not a link, I think I already saw all of them), but maybe a past experience of yours, I will be grateful.

Thank you !

Hi can you show your sketch for what you are doing. Pretty certain these
Phones use fbus

Sure, here they are:

Code using hardware serial transmission:

Code:

byte msg[] = {
  0x1E, 0x00, 0x0C, 0xD1, 0x00, 0x07, 0x00, 0x01, 0x00, 0x03, 0x00, 0x01, 0x60, 0x00, 0x72, 0xD5 };

void setup() {
  Serial.begin(115200);
  delay(1000);
}

void loop() {
  delay(7000);
  Serial.println("Start");
 
  // Initialise the F-bus
  for (int z = 0; z < 128; z++) {
    Serial.write(0x55);
   }
  delay(1000);

  // Send our command
  for (int x = 0; x < (sizeof(msg) / sizeof(byte)); x++) {
    Serial.write(msg[x]);
  }

  // Wait for a reply
  while (1) {
    delay(1000);
    while (Serial.available() > 0) {
      char c = Serial.read();
      Serial.print(c, HEX);
      Serial.print(" ");
    }
  }
}

Code using software serial transmission:

Code:

#include <SoftwareSerial.h>

#define rxPin 2
#define txPin 3

// set up a new serial port
SoftwareSerial mySerial =  SoftwareSerial(rxPin, txPin, true );

void setup()  {
  // define pin modes for tx, rx:
  pinMode(rxPin, INPUT);
  pinMode(txPin, OUTPUT);
  // set the data rate for the SoftwareSerial port
  mySerial.begin(115200);
  // For user output messages
  Serial.begin(115200);
}

void loop() { 
  // Initialise the F-bus
  Serial.println("Initializing F-Bus.");
  for (int z = 0; z < 128; z++) {
    mySerial.write(0x55);
  }
  delay(1000);
 
  // Send our command
  Serial.println("Send request.");
  byte msg[] = {0x1E, 0x00, 0x0C, 0xD1, 0x00, 0x07, 0x00, 0x01, 0x00, 0x03, 0x00, 0x01, 0x60, 0x00, 0x72, 0xD5}; 
  for (int x = 0; x < (sizeof(msg) / sizeof(byte)); x++) {
    mySerial.write(msg[x]);
  }

  // Read answer
  Serial.println("Read answer.");
  mySerial.listen(); 
  while (1) {
    delay(1000);
    while (mySerial.available()>0){
      Serial.print(mySerial.read(), HEX);     
      Serial.print(' ');     
    }
  }
 
}

All those were grabbed from previous links.
