Hi all,<br>
I am new here and thanks all for your efforts.<br>
I would like on my side to use the GTA04 for breadboarding with some
daughter electronics which will have its own batteries <span
class="moz-smiley-s3"><span> ;-) </span></span>. Is the USB the
only interface ? Is there some open collector output available
inside ?<br>
Best regards,<br>
Laurent.<br>

<pre wrap="">Would the GTA04 allow developers to have access to the GSM chip, or
the API to allow developers to play around with the GSM radio frequency?

<pre wrap="">We got the permission to put all AT-Commandos into our docs.
The interface is UART, so the only thing WE can provide is
this documentation and the schematic how this UART is wired
to our CPU.
BUT if you manage to write an alternative firmware
like it has been done for the GSM-Chip in the GTA02
then you can certainly do other things then just hopping between
the base stations and all the usual phone related stuff.
I'm not sure I got your question right.
Maybe you ment Monitoring and Injection?
Or using is for totally different purposes then GSM?
Then you will also have the problem of the dimensions of the circuits themself.

<pre wrap="">Also, would the USB OTG host chip be able to provide to full 500mA to power devices with?

</blockquote>
<pre wrap="">I don't know BUT I wouldn't do that neither.
Imagine how fast you batteries would be drained this way.
If you have electronics, which needs this amount of current
just patch some Pb-Akkumulator into the circuits as well...

<pre wrap="">You're welcome

<pre wrap="">I cannot wait for this. I'll be using this phone as part of my University project next year :-D.

<pre wrap="">Well...
Next year?
What project?
What university?
best regards
