Re: olimex pic gsm source code
Tell the truth, I don't use the olimex, I connect pic18f45k20 -> M33G GSM module (both 3.3V). But the problem is the same "i only read CR LF". I tried to pull up the RX and TX pin with 47k resistor. Tried to connect RTS to CTS, then DSR to DTR, but nothing. I...
Re: olimex pic gsm source code
I did what you suggest me, but it didn't help. It seems that I only get back the first and the second characters from all characters. I set the echo, I get the "AT" and no CR LF.
But I check the OERR after every ReadUSART, but there is not overrun.
Re: olimex pic gsm source code
But I would like to leave out the PC from the circuit. In this case I connect the serial pins (TX, RX) PIC<->GSM, then GSM RTS to an I/O pin of the PIC. Is it good?
Re: olimex pic gsm source code
But if I see the OK answer in the hyperterminal, why I don't see on the pin of the PIC? I connect only the RX and TX pin onthe PIC side, and on the PC side.
Re: olimex pic gsm source code
Could you explain how I should use the RTS line? At this moment I connect the PIC RX <- GSM TX, PIC TX -> GSM RX. I tried pull up the RTS but it does not help.
Thank you
