Enabling F-bus communications with Arduino




A few months ago I was looking into how to use Fbus with a Nokia phone but didn’t have much luck and instead just wired up the keypad. I decided to revisit Fbus and this time happened to find some AVR code which could send/receive SMS’s so now I’m able to send an SMS using the Arduino and I’ll explain how we do this.

Before I go any further the 3 resources I used were:
Embedtronics – F-bus packet explanation with some examples of a packet
Avr and nokia3310 interface(sms) project on AVRfreaks – Code for an AVR to send/receive SMS
Gnokii – F-bus documentation and code to run on a computer

Firstly you need a Nokia phone which the F-bus commands are known, the best documentation is available for the Nokia 6110 and derivatives (Nokia 6130, 6150, 6190, 5110, 5130, 5150, 5190, 3210, 3310) – this was found in \gnokii-0.6.31\Docs\protocol\nk6110.txt

I was able to purchase a Nokia 6150 from Ebay for under $20. You can search up the Nokia pinout for your mobile phone – I found the TX, RX and GND for my phone.

Enabling F-bus communications with Arduino circuit

The F-bus protocol uses 115,200bps so we can easily use the Arduino’s serial function to communication with the phone. All you need to is hook up the phones TX to the Arduino’s RX and then use a resistor divider (I choose 330 ohm resistors) to connect the Arduino’s TX to the phones RX as shown above.
