= researching the thuraya sg2520 smartphone =

 * made by apsi / www.apsat.co.kr

 * fcc id: TZ5SG2520, ( search [http://gullfoss2.fcc.gov/prod/oet/cf/eas/reports/GenericSearch.cfm here] )

 * the gsm part is a siemens MC 55 revision 0400

= software =

System OS of SG-2520 terminal is using Windows CE 4.2 Core and it is consisted of OMAP 

1510 CPU, ARM Core, RAM 128 MB, and Flash ROM 64 MB. Screen is 176 x 220 Pixel and it 

supports Bluetooth, IrDA, 1.30 Mega Pixel and SD card. File access is possible via ActiveSync 

but it does not support DB Sync.  

XP/2000 can be used as development environment and development tool is based on the 

Embedded Visual C++ 4.0 and you need to use the SG2520-CORE-SDK-8.2 Device of SDK.  

see [http://www.thuraya.com/content/thuraya-sg-2520.html this page] for instructions on how to update the phone to the latest firmware version.

== the usb connector ==

 * type: 3050-24R-0.5  from HJI&C

   * it looks quite a bit like a lg c1200 / zune / ipod connector.

 * i think we need [http://www.hyupjininc.com/english/product/product_sub.htm?item_code=3 3050-24P-0.5]

devices available on the connector:

 * uart1 : rx=pin13, tx=pin14, rts=pin20, cts=pin23

 * uart2 : rx=pin1, tx=pin3

 * i2c : pin7=SCL, pin11=SDA, irq=pin24

 * audio: mic=pin8+pin9, spk=pin17+pin18

 * usb: DM-=pin10, DM+=pin15, VBUS=pin16

 * Ground=pin12, pin19

 * extdevice power: pin21, pin22

 * external boot : pin2

 * charge voltage : pin4+pin5

 * external device attached signal : pin6

== you can connect to the internal modem as follows ==

 * from start -> connectivity -> bluetooth

 * turn 'on', and select 'dial up network'

 * move rocker switch to the right for the 'search' window

 * make desktoppc discoverable

 * select your desktoppc, then choose 'pairing' from the option menu

 * from your desktop connect to the dialup profile

 * talks at 115200 baud
