I need to make an "Data Call" directlly from a telephone to a telephone for exchange string data in synchronism mode (in only one session).
cell1 - cell2
cell1: make data call to cell2
cell2: open incoming call from cell1
cell1: send to cell2 "Hello"
cell2: send to cell1 "Bye"
cell1: close call with cell2
I need to NOT use SMS;
I have tryed to search a solution with AT commands (perfect for my test) but AT command seems to be not is supported on J2ME.
