Hello my dear friends

I have designed a project with LPC2364 and I have used a SIM900A for remote communications.
I have run the SIM900A properly with UART and I can send and receive SMS easily.

My problem is sending data by SIM900A , since I want to update the firmware of this project by SIM900A I need a point to point communication , my data size is about 64kB(flash size of LPC2364) and it's format is "Intel hex" .

If I can send the Hex file to my remote project , then I change it's firmware by Boot Loader.
Please help me to send files via SIM900A.

Thanks a lot.
