Hi everyone. In the context of a larger application, I need to transfer occasional, short messages from a cellphone to a PC.
A key requirement is near-instantaneous arrival of those messages; a delay of more than a minute or so would be considered a failure. Since SMSs can occasionally lag due to the network, I am not going to use them.
Rather, I want to build an application on the cellphone that takes the message from the user, initiates a data call to a modem on the PC, and sends the message through. A custom app on the PC will deal with what happens afterwards. Some checksum and retransmit mechanism will make sure of data integrity.
So, I need to know how to programmatically initiate a data call, send data through it, and terminate it. I heard that it's easier to do it with native calls rather than MIDP, but since I'm not quite sure of which phone it will run on and I'm not practical at all with Symbian development, I'd rather use Java.
Can anyone give me some pointers on this? I'm relatively new to MIDP development, and I have no clue on where to start with regards to data calls.
