Hi,
You could experiment a bit with the COPS command. Its located in src/
java/org/smslib/modem/athandler/ATHandler.java. Try to add a delay and
see what happens.
You can also add the following 2 lines in the same method where COPS
is:
getModemDriver().write("AT+CREG=1\r");
getModemDriver().getResponse();
You should recompile after every change. You can do this with ANT, or
with the IDE you are working with.
