This blog has moved OK, ok, I couldn't resist any longer, I had to open the liveview up. Here are the pics (click for larger ones):

hidden bluetooth antenna

Nice pictures.

If I'm not mistaken, looks like the bluetooth antenna lies between the display and the vibration motor when the device is closed.
Two metallic, electrically noisy devices covering the antenna doesn't seem like a good idea...

Yup, you're right!

I'm surprised it took you this long!

Christmas, eh? :)

Disassembly..

How did you disassemble the LiveView Device? =)

Re: Disassembly..

There are four internal plastic clips round the side; I *carefully* used a swiss army knife. Tricky 'cos the device is powered.

I'll post some pics of the clips on the case later; right now I've lost the bloody thing somewhere!

Higher res img for front-pcb close-up?

Thanks a lot for doing the teardown.

I intended to look-up the possible compatibility of FreeRTOS and Contiki with the liveview (both support the Cortex-M3 of the liveview), but, while the "rear PCB closeup" is a wonderful high-res image, the front one (the one with the chips!) is not.

Do you have a higher res of the front-pcb image?

P.S.: In the xda-developers forum I see that the firmware update seems to weight 200kB, suggesting that there is some flash apart of the 32kB included into the STM32F103C6. I would love to identify the Flash chip (and check if there is some RAM apart of the 10kB of SRAM), and what bluetooth chip they use...

Sure, I'll see what I can do

Hi, just updated it - click through for a mega-hi-res photo.

Which bluetooth profile?

Which bluetooth profile does the Liveview use?
Is it SPP?

I think it was yes
