Bluetooth 3.0 - HUR FUNKAR DET?

n0rth3rnlight · 11 sept 2010

Jag och en av mina vänner har båda SGS och vi försökte dela lite filer via BT. Har SGS stöd för HS (High speed) File transfer och i såfall hur aktiverar man det? När vi körde BT mot varandra var det i vanlig hastiget :/

[edit] Bluetooth v3.0 + HS
Version 3.0 + HS of the Bluetooth Core Specification[23] was adopted by the Bluetooth SIG on April 21, 2009. It supports theoretical data transfer speeds of up to 24 Mbit/s, though not over the Bluetooth link itself. Instead, the Bluetooth link is used for negotiation and establishment, and the high data rate traffic is carried over a colocated 802.11 link. Its main new feature is AMP (Alternate MAC/PHY), the addition of 802.11 as a high speed transport. Two technologies had been anticipated for AMP: 802.11 and UWB, but UWB is missing from the specification.[26]

Alternate MAC/PHY
Enables the use of alternative MAC and PHYs for transporting Bluetooth profile data. The Bluetooth radio is still used for device discovery, initial connection and profile configuration, however when large quantities of data need to be sent, the high speed alternate MAC PHY 802.11 (typically associated with Wi-Fi) will be used to transport the data. This means that the proven low power connection models of Bluetooth are used when the system is idle, and the low power per bit radios are used when large quantities of data need to be sent.
Unicast connectionless data
Permits service data to be sent without establishing an explicit L2CAP channel. It is intended for use by applications that require low latency between user action and reconnection/transmission of data. This is only appropriate for small amounts of data.
Enhanced Power Control
Updates the power control feature to remove the open loop power control, and also to clarify ambiguities in power control introduced by the new modulation schemes added for EDR. Enhanced power control removes the ambiguities by specifying the behaviour that is expected. The feature also adds closed loop power control, meaning RSSI filtering can start as the response is received. Additionally, a "go straight to maximum power" request has been introduced, this is expected to deal with the headset link loss issue typically observed when a user puts their phone into a pocket on the opposite side to the headset.

Bra fråga, har oxå kört mot en annan SGS telefon och tyckte det var olidligt slött, tycker det borde känna av automatiskt, men någon kanske vet hur man gör

Det är inte så att man måste ha Wifi igång då? Känns som att telefonen borde slå på detta automatiskt isåfall, men man vet aldrig.
