you have to create a serial up connection and assign a virtual com port to it. this is the one that you are going to use for MPM .
please search the previous post on this topic thread. |

the normal range for bluetooth is only about 10 meters, and thats with optimal conditions i think. |

@madmax
what would be considered optimal conditions?

Optimal conditions are open spaces with no interfering devices using the same band the BT uses. |

Bluetooth devices come in 3 classes:
Class 1: 100mW ~ +20dBm, 100m range
Class 2: 2.5mW ~ +4dBm, 15m range
Class 3: 1mW ~ 0dBm, 10m range
I think all mobile phones are class 3, to conserve battery. Most USB adapters are Class 2. MSI's however is class 1!
The ranges are the "officially" quoted, in theory 3 times this should be possible in space (Ie. vacuum... I think connecting between 2 kayaks over open water is very close to open space ).
A more realistic model gives indoor ranges of 10, 14, 40m respectively.
Actual connections are always two-ways. So the lower of the two directions range will apply (A class 1 connected to a class 3, should give 10m range).
The range also depends on the receiver sensitivity. The Bluetooth standard requires -70dBm, which is not very good (Cell phones can do *much* better), in order to yield cheap BT chips sets.
In simple (outdoor) models, an extra 20dBm gives 10 times the range (indoor values are more like 30dBm per 10x). That is why class 1 is listed as 10 times the range of class 3.
This is the same for reception sensitivity.
Ie. MSI claims -90dBm sensitivity, so in theory it should be able to pick up a class 3 device at 100m (or 40m indoors). As it is at the same time a class 1 transmitter, a normal (-70dBm) receiver should be able to pick it up at this distance too (ie. we have +20dBm both ways).
2 MSI devices talking to each other should have +20dBm from the transmitter power and +20dBm from the receiver sensitivity, for 1000m range outdoors (160m indoors). MSI does not advertice the extra range, but they do mention the -90dBm sensitivity, and then its up to anyone to do the math.
So your report that it does not have that much range is disappointing to me!
Indoor it should have 40m to ANY qualified bluetooth device, and over open water much more.... Unless they are exaggerating their reception sensitivity. (Or unless I'm mistaken somewhere along here )

Can anybody tell me what the speed of connection is in MB per second if you connect 2 PC's via Bluetooth??
Thanks in anticipation
