Point Of Interest: On early manufactured Stock Keeping Units (mostly with release firmware such as 1.06) there is a known issue with faulty 3G sub boards. For more information on how to remedy check the errors page: C2-9693-7.

Bluetooth

Bluetooth is a technology for creating personal area networks operating in the 2.4 GHz unlicensed band, with a default range of 10 meters.

An overview of Bluetooth:

Bluetooth radio

Bluetooth 2.0 uses frequencies between 2.4000 and 2.4835 GHz, and divides the band into 79 MHz channels (numbered 0-78), with frequency hopping at a rate of 1600 times per second. Channel 0 has a frequency centred at 2.4020 GHz, allowing a lower guard band of 2 MHz. Channel 78 has a frequency centred at 2.4800 GHz, allowing an upper guard band of 3.5 MHz. Bluetooth devices are divided into three classes, depending on their maximum transmitted power (and hence their maximum range):

Class Power Range
Class 1 100mW
(20 dBm)		 100m
(325ft)
Class 2 2.5mW
(4 dBm)		 10m
(32ft)
Class 3 1mW
(0 dBm)		 1m
(3ft)

Bluetooth connection

A PSVita can connect up to seven (active) Bluetooth® devices at one time.

There are three type of connections in Bluetooth:

  • Single-slave: a point-to-point connection (only 2 Bluetooth units involved)
  • Piconet: One Bluetooth unit acts as the master of the piconet, whereas the (up to seven active) others units acts as slaves.
  • Scatternet: Multiple piconets with overlapping coverage areas form a scatternet.

Bluetooth Profile

Bluetooth® devices that support the following profile can be paired with your system:

By using the Object Push Profile (OPP), on Firmware 3.18, the attempts forcing the connection to the Vita will give a loophole .

Bluetooth Adressing

Each Bluetooth unit has a unique 48-bit address (BD_ADDR).

Company_assigned Company_id
Lower Adress Part (24-bit)
transmitted with every packet as part of the packet header 		Upper Adress Part (8-bit)
 Non-Significant Adress Part (16-bit)
assigned publicly by the IEEE
lsbxxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxxmsb

Class of Device/Service (CoD)

In practice, most Bluetooth clients scan their surroundings in two successive steps: they first look for all bluetooth devices around them and find out their "class". You can do this on Linux with the hcitool scan command. Then, they use SDP in order to check if a device in a given class offers the type of service that they want.

The PlayStation Vita PCH-2000 has a class of Device/Service (CoD) 0x3e0100:

  • Major Service Class : Networking (LAN, Ad hoc etc) (0x20000)
  • Major Service Class : Rendering (printing, speaker etc) (0x40000)
  • Major Service Class : Capturing (scanner, microphone etc) (0x80000)
  • Major Service Class : Object Transfer (v-inbox, v-folder etc) (0x100000)
  • Major Service Class : Audio (speaker, microphone, headset service etc) (0x200000)
  • Major Device Class : Computer (desktop,notebook, PDA, organizers etc ) (0x100)
  • Minor Device Class : Uncategorized, code for device not assigned
