When I travel, GPRS is my lifeline. My trusty Nokia 6600 acts as the uplink “modem” for my laptop by emulating a dial-up connection to the operating system. The phone connects to the laptop in one of two ways: an IR connection, or a Bluetooth connection. My laptop is a couple of years old, so I use a Belkin USB-Bluetooth adapter (model number F8T001).
Although I would prefer to use Bluetooth exclusively, it seems to be much less reliable. When using Bluetooth, the phone will sometimes spontaneously restart or it just quits sending data through the GPRS connection. The problem does not occur with IR. It is so bad that it is rare to get more than 1.5 megabytes of data through the Bluetooth connection before I have to restart the phone, or it inexplicably reboots itself for me.
Whenever possible, I use IR as my first-choice connection method simply because it is much more reliable. Multi-megabyte transfers over IR just work, but Bluetooth connections freeze up before two megabytes.
I am on the road right now, but when I get more solid connectivity, I’ll have to search out updated software. I am still using the software that came with the adapter (1.4.2 build 10), so there might be an update. It is also possibly a problem with the Bluetooth firmware (version 525). Of course, I may be placing too much faith in a software update to solve my problems…
How does the reliability of your Bluetooth connections compare to other methods such as IR?
