Thanks again.

The SIM900D, after AT+FTPPUT=2,1024, return +FTPPUT: 1294.

I have a receive buffer, 1024 bytes, which receives the data from the PC.

After the full buffer, the firmware will read and send via G ...

Thanks Ttelmah,

When I add "TRANSMIT_BUFFER", the device does not send data to the PC via bluetooth (UART2).

What could be happening ?

Hello guys,

I need to send some data coming from a PC to an FTP server, through the PIC a SIM900D module.

The data is sent in packets of 1024 bytes via serial to the PIC, which stores in a ...

That's right.

Thank you Ttelmah.

I did the changes you said, but it did not work.

I checked that this problem only happens, when there is some command like output_high or output_low.

PIC24 does not generate uart1 interruption, when the function "envia_dtmf(10); " is called inside the main loop.

If I remove the function, it works.

Can anyone help?
