Most of the modern phones are based on the Symbian OS. These phones have broken the convention and replaced the traditional FBUS protocol framework by a new one. The new protocol provides synchronizational functionality, but the older one was more powerful. This is one of the reasons we decided that analysis of the new protocol is time wasting. A client-server application was created. The client part is built into libgnokii, the server part runs on the phone and is called gnapplet. These communicate with our own protocol and are tightly coupled, so you have to use the same version on both side.

Gnapplet source code of the server applicationis licensed under the GNU GPL, and can be downloaded from the gnokii cvs. Compiling gnapplet requires special tools, you can look into gnupoc ( Installing the Nokia SDK isn't easy, so we provide a pre-compiled version (file gnapplet.sis) in the utils directory of the tarball (last version of which can be downloaded from

(notice only contains obsolete versions)

You can install the SIS file as you would do with any other symbian application. You can transfer it to the phone over the OBEX protocol (OBEX is available over IrDA or Bluetooth or cable connection).

Configuration settings

You can use the following settings in your gnokiirc to access the phone:

Bluetooth connection

   port = _bluetooth_address_
   rfcomm_channel = 14
   model = symbian
   connection = bluetooth

IrDA connection

   port = /dev/ircomm0
   model = symbian
   connection = irda

TCP/IP connection

This is disabled by default, you have to edit gnapplet.ini on your phone to enable it.

   port =	(put the IP address of your phone here)
   model = symbian
   connection = tcp

Phone configuration

You have to start gnapplet first each time you want to use it (you'll find it in the phone menu), then start gnokii or xgnokii. After gnokii disconnects (or you won't connect in 30 seconds), the application will terminate. You can edit gnapplet.ini on your phone to change the timeout (set it to -1 for infinite) and the other settings.

The following are the default values:

irda_support = 1
bt_support = 1
bt_rfchannel = 14
tcp_support = 0
tcp_port = 1912
init_timeout = 30
reinit_timeout = 5


The current code is able to:

  • identify the phone
  • read/write/delete phonebook entries
  • read/delete call log (missed, received, dialled calls)
  • read the memory status
  • read network info
  • read RF/battery level
  • read/set clock, read/set alarm
  • read/write/delete calendar entries
  • read/write/delete todo entries
  • send/receive sms
  • read profile entries, read/set the active profile


  • phonebook handling is quite limited:
    • name isn't set or read correctly
    • missing attributes
    • no group handling
    • missing SIM memory handling
  • gnapplet seems to not work on SymbianOS v3 devices (eg. Nokia 5500)


  • implement the missing things :-)
