Hi!

trying to connect my t630 to the Javelin Stamp, sitting on a demo board, but I can't seem to get it right. It seems like the at commands that are sent from the stamp aren't right some how. could it be from lack of handshaking and flowcontrol?

    If you are using the Javelin Programming port as a vanilla-RS-232 port -- you can't do that. The Javelin programming port is dedicated to debug use with the IDE -- it has a *lot* of 'odd characters' sent back and forth.

    You may need to add a MAX232 circuit, and use some other pin on the Javelin to talk to the t630. The Javelin implementation can have multiple "virtual UARTs" -- but you can use the existing programming port for that.

    Im currently using a demo board containing two rs232 connectors. one is connected to the computers serial port com1, and the other is connected to the t630.

    I've tried connecting the second rs232 to the computers com2 in order to read the signals being issued by the Javelin Stamp in HyperTerminal and with Portmon. I discovered there is a difference between what HyperTerminal sends to the Mobile, and what the Javelin chip does - both issuing the same AT-commands.. confused.gif

    Appreciate any and all help turn.gif
