Very slow Bluetooth transfer speeds. |

I am using a MSI BToes Bluetooth dongle with MyPhoneExplorer. The maximum speed I've achieved so far is about 30kBps (and varies between 25 ~ 30 when transferring). The specification says it supports up to 90kBps. Why am I getting 1/3 of the rated speed? I downloaded the latest BT drivers from MSI site, no difference. |

Maximum speed depends on both devices.
Normally transfering to the phone maxi should be around 45kbs.
When I transfer to my phone W800 it range between 37 and 45.
I think the phone is slowing everything down, because even the usb is slow.
But according to the usb 2.0 specifiations it should be really fast. |

What are you using to transfer files ? at least 45 is better than 25~30 
As far as I know K750 supports Bluetooth version 2.0 which has a theoretical speed of 3MBits/s, however in reality I don’t think the phone can go anywhere near those speeds, but since it supports version 2 it should at least be able to work with the maximum rate of 1.2 which is 723KBits/s (90KBps), don't you think ?
I prefer to use the dongle cos its easier to use than the cable, therefore it would be a grate help if someone can tell me a way to boost my speeds to around 70~80KBps.

No... the speed you'll get via BT is, as stated, around 40-45 KB/s...  |

The white paper of K750 states it has a BT transfer rate of max 600 Kbps (75 kb/s). However, due to overhead in the transfer protocol, interference and distance between devices, 45-50 kb/s is more realistic as max transfer rate.

According to this thread, some are getting better speeds than 45~50. mario2002 claims he can get 70KBps with BT 1.1/1.2 compatible dongle. |

To my knowledge mario2002 has no K750. He prefers Nokias and the S60 OS. If you connect K750 to a BT 2.0 dongle, you may of course get better speed than if connected to a 1.1/1.2 dongle. But I doubt you can come up tp 70 kb/s (seeing is believing - so go and buy a BT 2.0 dongle ). Also, it seem transfer to/from MS is faster than transfer to/from K750 internal memory, at least through USB (possibly its same with BT).

I managed to improve my speeds to around 40~46KBps by upgrading Bluetooth drivers. The latest BToes driver (as MSI calls it) is actually based on Widcomm 4.0.1.2101 BT driver. Then I found out that there is a newer version 5.0.1.802, so I downloaded and after meddling with the patch files I finally managed to get it working with the MSI dongle. And it is lot faster than what I had before.
However now there is an even newer version : 5.0.1.1200 but it seems there is no working patch for it yet |
