I tried to use this example to write to a device I have connected to serial
port /dev/ttyO1. I know the device answers because I can use screen and
get responses. My code to send out "/sh/s" is:
var b = require('bonescript');
var cmd = '/sh/s';
var port = '/dev/ttyO1';
var options = {
baudrate: 9600
};
b.serialOpen(port, options, onSerial);
b.serialWrite(port, cmd);
function onSerial(x) {
if (x.err) {
console.log('***ERROR*** ' + JSON.stringify(x));
}
if (x.event == 'open') {
console.log('***OPENED***');
}
if (x.event == 'data') {
console.log(String(x.data));
}
}
I get the following response:
debian@beaglebone:~/nodews$ node shedrd.js
/usr/local/lib/node_modules/bonescript/my.js:55
var slotRegex = new RegExp('\\d+(?=\\s*:.*,bs.*' + pin.key +
')',
^
