Some time ago i’ve bought Nokia E50. It’s a quite impressive phone, although the iphone made some not so right hype about itself nowadays. Anyway i’ve configured almost everything but the GPRS connectivity. When the Ethernet link was in a good shape i wasn’t worry about it, and honestly i’ve got many more interesting ways to spend my free time 😉
Unfortunately some days ago a big storm hit Cracow, and my Internet provider has found himself on the knees with the storm’s damages. The Internet link wasn’t working and i’ve got something important to send by an email. After this i’ve considered once and for all to configure my linux box for gprs connection with this phone.
I’ve chosen Bluetooth and the GPRS/Edge connectivity. After some searching on the net i’ve found no easy solution (working on my computer/phone). Now i’ve finally made everything running smoothly and thus i’ll write something about it. I’m using Polish Orange provider (Orange Polska/Idea).
- Make sure you have connected phone and the linux box and exchange keys (it’s mentioned all over internet and i’m not going tell you how to do it).
- All of examples provided below has last 3 hex pairs of bluetooth address masked with the xx:xx:xx for a privacy reason
- Next find your phone with the command hcitool scan
- response should be something like:
zorba@thinkpad:~$ hcitool scan Scanning ... 00:19:B7:xx:xx:xx Zorba zorba@thinkpad:~$
- next search for Dial Up Network capability (DUN) with the command sdptool search dun
- result should be like:
zorba@thinkpad:~$ sdptool search dun Inquiring ... Searching for dun on 00:19:B7:xx:xx:xx ... Service Name: Dial-Up Networking Service RecHandle: 0x100a7 Service Class ID List: "Dialup Networking" (0x1103) Protocol Descriptor List: "L2CAP" (0x0100) "RFCOMM" (0x0003) Channel: 2 Language Base Attr List: code_ISO639: 0x454e encoding: 0x6a base_offset: 0x100 Profile Descriptor List: "Dialup Networking" (0x1103) Version: 0x0100 zorba@thinkpad:~$
- result should be like:
- It has found DUN on the channel 2 (mark as bold above)
- Next configure rfcomm for the channel 2 with the command
sudo rfcomm bind 0 00:19:B7:xx:xx:xx 2
- It has binded your phone with the channel 2 for the 0’th rfcomm device
- Now it’s all ready for the ppp communication !
Save provided ppp configuration files below in your /etc/ppp/peers directory. I’ve found this configuration over the net and make some changes in order to make it works on the Nokia E50 phone.
Changes made are:
- in gprs added:
- connect-delay 6000
- changed the user to “internet” as required on polish orange network
- in the gprs-connect-chat make some changes in the names of the connection string
Example communication log
This is my communication log with the orange network. Please bear in mind, that some differences might be with your case, but not so substantial.
