I'm not expecting to see any many much more surprises, this late in the marketing period.

IT LOOKS LIKE IT!


Well I think we're all in for a treat regarding bluetooth, as the N900 (Does have the ability) for a bluetooth 3.0 upgrade!!!
Heres what I've discovered:-

The Bluetooth chip inside the N900 is a BCM2048, manufactured by broadcom. Now on the broadcom website it states.

The Broadcom BCM2048 is a monolithic 0.13 μm single-chip Bluetooth 2.0+EDR compliant stand-alone baseband processor with an integrated 2.4-GHz transceiver, integrated FM and RDS/RBDS receiver, and an integrated FM baseband processor. It features the highest level of integration and eliminates all critical external components, thus minimizing the footprint and system cost of implementing a Bluetooth and FM solution. The BCM2048 has been designed to support key features of next-generation Bluetooth technologies.

The BCM2048 is the optimal solution for any voice and/or data application that requires the Bluetooth SIG standard Host Controller Interface (HCI) via a high-speed UART and PCM. The BCM2048 incorporates all Bluetooth 2.0+EDR features including eSCO, AFH, fast connect, all EDR packet types and lengths, and all errata.
The BCM2048 also includes InConcert® and other industry collaborative coexistence solutions with WLAN systems.

Now the highlighted parts do sound good, for a 3.0 upgrade, but it gets better...
Inquisitive as to what their InConcert solution actually is, I found that its a technology designed to allow Bluetooth and Wi-Fi wireless devices to co-exist and operate collaboratively in mobile devices such as netbooks, notebooks and smartphones. InConcert technology lets products enabled with Broadcom Bluetooth and Wi-Fi chips intelligently share the 2.4 GHz frequency range, coordinating transmissions to optimize throughput and performance as required by a range of applications.

And finally, Broadcom lists the features of this chipset as:-

* Highly-integrated single-die Bluetooth and FM/RDS with low external BOM cost and small footprint area < 35 mm²

* Best-in-class RF sensitivity for both Bluetooth and FM with no loss of performance under concurrent operation

* Flexible control and digital/analog transport interfaces for ease of integration into cell phone and MP3 player designs

* Firmware migration path to new Bluetooth specifications

So there we have it, our beloved N900 has a future-proof BT chipset

See the detailed N900 hardware specs at http://natisbad.org/N900/n900-commen...are-specs.html

At Bluetooth section it says v2.1 not sure about it could be updated to BT 3.0 via software upgrade.

I see max 200 KB/s so far during a file trasfer using N900 Bluetooth. What is your max rate?

My max rate is the same, around the 200 KB/s, the N900 is supportive of BT 2.1 + EDR however there is no increase of speed between 2.0 or 2.1. Both specifications support EDR (Enhanced Data Rate) Bluetooth Core Specification Version 2.1 + EDR is fully backward compatible with 1.2. The headline feature of 2.1 is secure simple pairing (SSP) this improves the pairing experience for Bluetooth devices, while increasing the use and strength of security. 2.1 also allows various other improvements, including Extended inquiry response (EIR), which provides more information during the inquiry procedure to allow better filtering of devices before connection and sniff subrating, which reduces the power consumption in low-power mode.
Bluetooth 3.0, 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.
The features of BT 3.0 are:-

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.

So with Broadcom specifying that the BCM2048 chipset has a Firmware migration path to new Bluetooth specifications, and that the chipset includes their InConcert® technology which lets products enabled with Broadcom Bluetooth and Wi-Fi chips share the 2.4 GHz frequency range, it all add ups for a 3.0 upgrade.

Further adding, On June 12, 2007, Nokia and Bluetooth SIG had announced that Wibree will be a part of the Bluetooth specification, as an ultra-low power Bluetooth technology.
A few days ago (April 21) the Bluetooth SIG completed the Bluetooth Core Specification version 4.0, which includes Classic Bluetooth, Bluetooth high speed and Bluetooth low energy protocols. Bluetooth high speed is based on Wi-Fi, and Classic Bluetooth consists of legacy Bluetooth protocols.

Bluetooth low energy is a recent enhancement that allows two types of implementation, dual-mode and single-mode. In a dual-mode implementation, Bluetooth low energy functionality is integrated into an existing Classic Bluetooth controller. The resulting architecture shares much of Classic Bluetooth’s existing radio and functionality resulting in a minimal cost increase compared to Classic Bluetooth. Additionally, manufacturers can use current Classic Bluetooth (Bluetooth V2.1 + EDR or Bluetooth V3.0 + HS) chips with the new low energy stack, enhancing the development of Classic Bluetooth enabled devices with new capabilities.

Single-mode chips, which will enable highly integrated and compact devices, will feature a lightweight Link Layer providing ultra-low power idle mode operation, simple device discovery, and reliable point-to-multipoint data transfer with advanced power-save and secure encrypted connections at the lowest possible cost. The Link Layer in these controllers will enable Internet connected sensors to schedule Bluetooth low energy traffic between Bluetooth transmissions.

Expected use cases for Bluetooth low energy technology include sports and fitness, security and proximity and smart energy. Bluetooth low energy technology is designed for devices to have a battery life of up to one year such as those powered by coin-cell batteries. These types of devices include watches that will utilize Bluetooth low energy technology to display Caller ID information and sports sensors that will be utilized to monitor the wearer's heart rate during exercise. The Medical Devices Working Group of the Bluetooth SIG is also creating a medical devices profile and associated protocols to enable Bluetooth applications for this vertical market.

well if you all say its not possible, what technology is used in this video on the nokia beta labs, with transfers a full musicalbum in 10 seconds?

can someone tell me wich technology is used here? i dont see any wifi nor bluetooth active on the n900 screen in this video.

is it true that we can jump to bluetooth 3.0???

Now that is fast oO

Car audio works just fine for me (A2DP).
