Bluetooth 2.0 EDR

---

I was just wondering what it means that the trinity supports BT 2.0?
Nowhere on the box or in the manual does it mention EDR which means enhanced data rate, ie faster.
I have a BT 2.0 dongle branded as a qtrek and use the tweaked widcomm drivers version 5.1.0.1100 which are great btw. Also the dongle is attached to USB 2.0 socket with no other devices eating up bandwidth.
But the speeds are nowhere near the 2.5 to 3 Megabit/s range which is the speed for BT 2.0 EDR.
I was just wondering what other ppl's experience's are with BT speeds.
Other then the speed I find BT to work great with this pda

P3600 does not support EDR.

Whats the point of EDR? Its fast... but for what purpose? File copying?

A2DP can use up all BT 2.0 (without EDR) bandwidth, hence, Trinity's Bluetooth can do nothing when u listen music by bt stereo.

Now, u know why EDR is important, right ?

A2DP "only" uses 256/320 kbps (+ some additional overhead). That is, EDR isn't absolutely needed to achieve good A2DP quality. The Widcomm BT stack, for example, work just great without EDR.
