The communication of the Modem appears to be PCIe, instead of the more common (Used on WWAN modems for laptops.) USB interface. So, the Vita might have PCIe available for use along with USB. In case anyone wants to try putting a mPCIe SSD in it or even hook up an external GPU to the Vita.

=== 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):

=== 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.
 
=== Device icons ===
 
Shows the types of found Bluetooth® devices using icons.

=== Bluetooth Profile ===
 
*http://en.wikipedia.org/wiki/List_of_Bluetooth_profiles
 
Bluetooth® devices that support the following profile can be paired with your system:
 
*[https://developer.bluetooth.org/TechnologyOverview/Pages/A2DP.aspx A2DP (Advanced Audio Distribution Profile)]
*[https://developer.bluetooth.org/TechnologyOverview/Pages/AVRCP.aspx AVRCP (Audio/Video Remote Control Profile)]
*[https://developer.bluetooth.org/TechnologyOverview/Pages/HSP.aspx HSP (Headset Profile)]
*[https://developer.bluetooth.org/TechnologyOverview/Pages/HID.aspx HID (Human Interface Device Profile)]
*HFP (3G model only?), PBAP (3G model only?), PAN (all models?)?
 
By using the Object Push Profile (OPP), on [[Template:Firmware_revisions|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).

=== Class of Device/Service (CoD) ===
*[[Components]] (Parent Component is Half Mini PCIe Module)


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 [https://www.bluetooth.org/en-us/specification/assigned-numbers/baseband class of Device/Service (CoD)] 0x3e0100:

On motherboard backside, there are a Marvell 88W878S-BKB2 Avastar WLAN/Bluetooth/FM Single-Chip SoC.

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.

Mobile Data Modem[edit | edit source]

Qualcomm Gobi is a family of embedded mobile broadband modem products by Qualcomm. One of the more notable products that contain a Gobi modem is the PSVita, which contains a MDM6200™ (note:the MDM6600 got closer specs than the MDM6270).

The communication of the Modem appears to be PCIe, instead of the more common (Used on WWAN modems for laptops.) USB interface. So, the Vita might have PCIe available for use along with USB. In case anyone wants to try putting a mPCIe SSD in it or even hook up an external GPU to the Vita.
