CHEERS
The idea is that when the application is received a message with the word name of a color ( only two for tests ) a panel change color . it is tried by sending a message from normal phone 3g and works and not there message notification , but when sent from a module ( sim900 : sending sms) , in the device is running the application a notice notification appears and block the operation of the application.
My application is created with the tutorial to receive messages without notice.
I think the two devices send different types of SMS, I'll have to check , thanks anyway .
