| Send Latitude and Longitude by module sim908 (FTP server). |

I want to code for send GPS signal by FTP server. But code it doesn't run.
Help me!!
Thanks
Code here is send GPS data to web and send sms(GPS, temperature by DHT11) to phone when have a messenger.

basic help....
1) does the PIC run the classic '1 Hz LED program'?
2) does the PIC run the 'Hello PC' program'?
3) does the GPS work with a PC ?
4) what interface does the GPS have ?
5) add 'errors' to the use rs232(...options..)?
6) send 'messages to PC ' for EVERY GPS communication
7) most GPS units are usually 3 volt, your PIC is 5 volt !!
8) delay_ms(xx) CANNOT be greater than 65535 !!
9) 'it doesn't run' is NOT helpful. You need to breakdown the program into sections that do. Send messages to a PC or local LCD module to confirm an action has been done(true or false).Use a PC the way your PIC program is coded..does THAT work ?
10) you need to use 'streams' for serial communications. Set one up for 'GPS' UART, the other for the 'SERVER'. Right now ALL communications go to the UART on C6-C7.

always happy to help

thank for your help.
I connected to my PC and test ok. GPS and FTP server is running follow mind.
So. I have all AT-command to connect module sim908. |

| delay_ms(xxx) less than 65535. But when I send a AT-command is AT+FTPPUT=1. The firsly is "OK" receive and after about 7second is receive +FTPPUT:1,1,1200. So I use delay_ms more than 65535. Can you help me the error. |

I connected pic18f4620 with PC and when I send a command from pic to module sim908 is receive. Not error.
I use only one UART because I can use AT-command to get GPS signal. |

hmmm...
1)
#use rs232(baud=56000, parity=N, xmit=PIN_C6, rcv=PIN_C7)
baudrate looks 'wrong' to me, maybe should be 57600 ??
2) always add 'errors' to the use rs232(...options....). This will prevent UART from 'hanging'(stopping) due to overrun condition( more than 3 characters coming in before program handles them).
3) delay_ms(65535) is over 1 minute( 65.535 seconds)..... way too ling for ANY serial communications...
4) you need to add some kind of verification that EACH 'print to GPS' is correct. Usually you take an unused pin,configure as a software serial port, and send messages to a PC terminal program OR send to a local LCD module. You need this for properly debugging what is going wrong.

Just a comment.
A 'delay_ms(65535);', is _65.5 seconds_. 7 seconds is only delay_ms(7000).... |
