Hi everybody.
I make some tests with software loopback to test the speed and reaction of
RS232 and BT.

Both testing software uses only a few Winapi calls (overlapping).
Hardware was several USB BT dongles as Gigabyte , PROMI etc
For timing analyze , I used the USBEE logic analyzer.
I installed every available driver without any difference.

The results was:
RS232 : TX -> RX 10ms
BT       : TX -> RX 70ms

Why in case of BT was such a delay ?
Can someone help me ?
