GSM Library updated (GSM V1.01)
The GSM library was refined, comments were improved and some functions were added or updated!
Differences compare to previous version (V1.00) are described at the end of this document. The main changes are that it is possible to make an authorization of caller number (call and SMS), deactivate DTMF receiver outputs so that these signals can be used for another purpose (Ethernet Shield) and to have a direct printing of a Debug information on the serial line.
All sketches were updated about the new library features and we have also added a new sketch ATcommandsTest.pde showing how to send an AT command directly from the sketch and how to receive a response. It is also a good example about how to use an advanced debugging possibilities using the serial terminal.
