Sumber : http://www.teaparty.net/technotes/blue-gprs.html
Linux : Ubuntu 5.04
Bluetooth USB
GSM/GPRS : Matrix (Indosat)

Install bluez-utils.
Saya menggunakan bluetooth USB.
Colok BT ke PC.
Cek dmesg | grep USB kira-kira akan terlihat spt :
---------
usb 2-1: new full speed USB device using uhci_hcd and address 2

---------

Nyalakan BT di Nokia.
Scan BT dari Linux

$ hcitool scan

Sekarang kita cari channel Dial Up Network.

Untuk menjalankan koneksi GPRS.
Jalankan :

$ rfcomm release 0

$ rfcomm bind 0 00:11:9F:EC:59:29 2

$ cat < /dev/rfcomm0

Isi PIN di Nokia 9500

Isi PIN di Linux.
Jika tdk muncul dialog PIN. Jalankan command 'xhost +' . Ini trik kasar. Lihat man xhost .
Ulangi cat < /dev/rfcomm0
Ketik Ctr+C untuk kembali ke prompt.

$ pppd call gprs
