Might we needed to research bluetooth 3.0 specifications...
BT device on TV uses 8 pin connection to TV. I could guess it as USB if uses 4 pins only.
We could eavesdrop those pins using device like pirate-bus or arduino like device. But I guess interpreting 6 binary data line (there must be needed ground and power lines, remaining cables for communication) will not easy after capturing signals..

Guessing (wildly) from PS51D550 service manual (Mstar-X5 based D-Series 3D-capable PDP, see: http://elektrotanya.com/samsung_ps51d55 ... nload.html), BT module connector pinout should (?) be like this:erdem_ua wrote:BT device on TV uses 8 pin connection to TV.

Code: Select all
1 Reset_Module
2 VCC 5V
3 USB D-(BT)
4 USB D+(BT)
5 GND
6 3D Sync Out
7 3D Sync In
8 NC

Re: Bluetooth support for 2011 3D glasses
Wow, thanks for the help.
But what is the meaning of 3D Sync Out & 3D Sync in pins? Why does they uses those pins instead of standard USB interface? Due latency? THat means problem.
If this means we cannot replicate this via ordinary BT 3.0 dongle. At but at least we could try to eavesdrop USB lines...

It is pricey ~$110, but worth for what it made...
Who will buy this?

I offer $100 bounty, who let us use this glass with our PC, with a cheap USB-BT dongle.

Broken SSG-3100GB (deconstructed):
- Broadcom BCM20730
- 24.000 crystal
- 24C128A (I2C EEPROM 128Kbit / 16Kbytes ?!!!)
- unidentified IC, marked as "BHT TI..I 0A86", 12pin/10pin (DC/DC step-up converter/voltage regulator?)
- two unidentified ICs (one per lense, 10pin) - LCD shutter drivers (?)
Test pads:
- TX, RX (integrated BCM20730 Cortex M3 serial interface, perhaps ?)
- GND, VBAT, 1V2, 10V
- LCH1, LCH2, RCH1, RCH2
- KEY, SHDN (shutdown ?), RED, YG, RST (reset ?), TMC, RF (radio/antenna)
Edit: left/right LCD shutters respond nicely to AC (+/-) 10V voltage.. I can't test RX/TX interface- unfortunately, BCM20730 is fried/EMPed . I wonder what exactly is serial EPROM IC used for: 16kB seems way to big for configuration purposes only; perhaps there is some kind of microcode in there?

I also found some ZigBee references in the firmware and serial log.
Apparently ZigBee is an otpion on some models.
