Encapsulate AT command method
FAQ, October 21, 2014 - 2:36pm, 7763 views
Hi,
A convinience way to encapsulate the AT command method inside your MIDlet for easy use and to avoid to add the string "\r" in every call to the ATCommand class.
A posible way for the implementation:
private ATCommand ATC; private String sendCommand(String command) { try { if (ATC == null) { ATC = new ATCommand(False); //no at comand send to the method } String answer = ATC.send (command + "\r"); Thread.sleep (100); // Remember at least to implement 100 ms sleep in order to recevie any URC return answer; //Return the AT command execution answer } catch (Exception e) { // implemment the treatment for the exceptions in this block } }
The call to the Method, examples:
sendCommand("ATI1");
sendCommand("AT+GSN");
sendCommand("AT+CIMI");

Overwrite the existing ATCommand class is a better approch for two reasons.
1) ATCommand is a limited resource and has to be released, but create and release same objects all the time should be avoided for performace and memory reason.
2) Sometimes a AT command has to be terminated by another character than '\r'. e.g. sending an SMS.
Here an example to overwrite the ATCommand class:

I started out with nothing... I still have most of it.
