Hello everybody, 
I am monitoring a status of a sensor interfaced to P89V51RD2(8 bit
controller)and want to send a SMS to any mobile number fed into the
controller.But i am not getting the GSM modems in which i will insert
a sim card and can be interfaced</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Interfacing modem to microcontroller</title><link>https://community.arm.com/thread/49174?ContentTypeID=1</link><pubDate>Mon, 24 Dec 2007 06:11:36 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:ed85171f-58d4-4857-bfaf-cb1111cabf40</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
&lt;i&gt;&amp;quot;Can anybody of u provide me some links or Lists of GSM modems
which can be selected for this purpose.&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Trying to keep such a list up-to-date would be a thankless and,
probably, fruitless task.&lt;/p&gt;

&lt;p&gt;
Just use your normal internet search engine, and search for &amp;quot;GSM
modem&amp;quot;.&lt;br /&gt;
Also try &amp;quot;embedded GSM modem&amp;quot;.&lt;/p&gt;

&lt;p&gt;
Then narrow the results down to the ones that available in your
locality, and meet any other specific requirements that you may
have.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Interfacing modem to microcontroller</title><link>https://community.arm.com/thread/51367?ContentTypeID=1</link><pubDate>Mon, 24 Dec 2007 03:13:14 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:e0396991-4b96-4d1d-b6fe-a234ed99ac20</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
Such a list would be very long - especially since there are a huge
number of obsolete models out there, that can be had for a low cost,
but isn&amp;#39;t suitable for mass-production.&lt;/p&gt;

&lt;p&gt;
Most mobile phone manufactureras (and a number of other
manufacturers) produces GSM modules for embedded usage, i.e. supposed
mount directly on a PCB. They normally interface with a uC using a
TTL-level serial interface or USB.&lt;/p&gt;

&lt;p&gt;
Besides that, all better mobile phones may be used as GSM modems
with a suitable adapter cable.&lt;/p&gt;

&lt;p&gt;
Contact one of the distributors for the major brands, and don&amp;#39;t
forget that you also need to get the required documentation of the
command set.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
