SquareJ has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to simply send a message to another XBee device using the XBee module. I have cut and paste from the module page but cannot get past the simple error below. syntax error at line 12, near ") {" Execution of aborted due to compilation errors. Also, does anyone have some working code to send data to and from XBees? Perl examples seem to be non existent : (
use strict; use Win32::SerialPort; use Device::XBee::API; use Data::Dumper; my $rx; my $serial_port_device = Win32::SerialPort->start ("tpj4.cfg") || die; my $api = Device::XBee::API->new( { fh => $serial_port_device } ) || +die $!; if ( !$api->tx( { sh => 0, sl => 0 }, 'hello world!' ) { die "Transmit failed!"; } $rx = $api->rx(); die Dumper($rx);
Using the following for tpj4.cfg
Win32::SerialPort_Configuration_File -- DO NOT EDIT -- \\.\COM3 CFG_1,none eol,10 clear,-@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ +@@@@@@@@@@@@@- RCONST,1000 istrip,0 CFG_2,none XOFFCHAR,19 PARITY_EN,0 WCONST,200 intr,3 U_MSG,1 STOP,1 XONLIM,2048 erase,8 XONCHAR,17 BINARY,1 RTOT,0 echonl,0 XOFFLIM,512 icrnl,0 inlcr,0 READBUF,4096 igncr,0 EOFCHAR,0 WRITEBUF,0 RINT,4294967295 ocrnl,0 bsdel,  opost,0 echoke,1 PARITY,none HNAME,localhost echoctl,0 CFG_3,none EVTCHAR,0 icanon,0 isig,0 HADDR,0 E_MSG,1 DATA,8 DVTYPE,none echo,0 quit,4 s_eof,26 s_kill,21 ERRCHAR,0 onlcr,1 ALIAS,COM3 HSHAKE,none DATYPE,raw echok,1 echoe,1 BAUD,57600 WTOT,10

    You are missing the closing paren for the if statement:
    if ( !$api->tx( { sh => 0, sl => 0 }, 'hello world!' ) ) { 1 2 1 ^-- add
    Don't feel too bad that you missed it. Sometimes the easy ones like these are the hardest to see. That's why a second pair of eyes can be so important!

      With some help from JEagle himself i am now able to talk to remote XBees too. Below is a simple AT get request. Jason
