Propeller and TeLit_865 Cellular Project Start-up, Need advise.

John Michael

I have started this Program to send AT commands to a TeLit 865cf Cellular module via the Propeller for SMS messaging. This is Just the starting point to verify that the TeLit_865cf module is receiving the commands from the Propeller, learning as I proceed with this project so please be patient :>) I am using a PDB and ViewPort to monitor transmission and just learning these as well. I need help to make sure that I am using Extended_Full_Duplex_Serial correctly and have made comments on the lines that I need Help with. Any advise would be Greatly appreciated and I hope this helps other's delving into Cellular as well.

CON
  _clkmode        = xtal1 + pll16x           ' Feedback and PLL multiplier
  _xinfreq        = 5_000_000                ' External oscillator = 5 MHz
  wait = 5_000_000

VAR
   long stack[30]

   serial : "Extended_Full_Duplex_Serial"

PUB MAIN
  serial.Stop
  serial.RxFlush
  serial.start(31,30,0,115,200)

  
  serial.str(String("AT+CMGF=1"))                              'I will comment these commands once I make sure I'm using the Object correctly.
  wait
  serial.str(String("AT+CPMS="ME""))

  wait
  serial.str(String("Testing Equipment")                       'Text Message to Send to Cellular Device.
  wait

  serial.Stop                                                                     'Stop the Cog that the call to Extended_Full_Duplex_Serial started.

Found the dec. Equiv. For ENTER ...
Moved my finger off the Enter key while looking at the ASCII chart :-)

Ordered a Level translator from SparkFun to handle the Voltage difference on the RS232 lines. NOTE: Rx on the TeLit does not have a Internal Pull-up, we may have to use a 47K ...
Will Post the up-dated code later tonight.
