The final working code was:
<html> <head> </head> <body> <script src="https://www.puck-js.com/puck.js"></script> <script> var d = new Date(); var n = Math.round(d.getTime()/1000); var puckCommand = String.fromCharCode(16)+"setTime(" + n + ")\n"; </script> <button onclick="Puck.write(puckCommand);">Set The Time</button> <button onclick="Puck.eval('new Date().toString()',function(x) { console.log(x); })">Get The Time</button> </body> </html>I never got \x10 working in the code. As you said, there must be some HTML escaping going on somewhere.
-
So the bad news is that \x10 or even \\x10 doesn't work (I've tried so many variations around that). The good news is that changing \n to \n in puckCommand solves the overall problem and eval() happily runs now after write(). Thanks for all the help!
-
So I can replicate the write/eval error in devtools console when \x10 is excluded. But when I include it, it works, as you predicted. So I'm clueless as to why it's not working in the code on the page.
-
Hmm. Typing that in the devtools console works for me too. I must be missing something very obvious.
Code is on: https://conorpuckjs.now.sh/web_bluetooth_set_time.html

Still no joy. Same error which is very weird.
-
What does the char code do? Disable echo?
I'm getting a different error now:
Uncaught SyntaxError: Got '\' expected EOF -
I've hit that problem a few times. e.g. right now one of my Puck.write() calls is working but when I follow it with a Puck.eval(), it throws a JSON error which turns out to be due to trying to parse
Bluetooth.println(JSON.stringify(new Date().toString()))Still trying to figure out what interaction of write() and eval() is causing that to appear as the response to eval(). Doing two eval() in a row is fine. And if I do write(), eval(), eval(), the second eval() is fine so write() is causing some issue.
<html> <head> </head> <body> <script src="https://www.puck-js.com/puck.js"></script> <script> var d = new Date(); var n = Math.round(d.getTime()/1000); var puckCommand = "setTime(" + n + ")\\n"; console.log(puckCommand); </script> <button onclick="Puck.write(puckCommand);">Set The Time</button> <button onclick="Puck.eval('new Date().toString()',function(x) { console.log(x); })">Get The Time</button> </body> </html> -
Not sure what the best way to report that back to users is.
-
Aha that's it, thanks Gordon. Working like a charm now for several different expressions. I missed the lack of a semicolon in the example.
-
I have Puck.write working fine but Puck.eval is throwing an error on Chrome on Ubuntu.
Same error no matter what command I try, even 1+1.
<button onclick="Puck.eval('1+1;',function(x) { console.log(x); })">Get The Time</button>This is on 1v92.
Am I missing something obvious? Thanks!

Good to know re month, thanks.
Ahhhhhhhhhhhh, getDay() is Day of Week!
User error completely :-) Ignore me ;-)

Hmm, it's right:
"Fri Jun 9 2017 10:36:48 GMT+0000"

I've having a weird issue on Puck with datetime.
I have "Send time to Espruino" set in the IDE.
If I do new Date(Date.now()).getHours() or new Date(Date.now()).getMinutes(), I get the right thing.
But new Date(Date.now()).getMonth() is returning 5 and new Date(Date.now()).getDay() is also returning 5. (That's for today). Yesterday it was 4 for getDay().
This is on 1v92 using standalone Windows IDE espruino_ide_win64_0v65.9
Any idea where this offset could be coming from?
-
Thanks Gordon. I'm pretty sure I was on stock 1v91. I followed your steps above and it's working fine now.

I've just tried this update from both nRF Toolbox and nRF Connect on Android and in both cases it results in Puck.js flashing all three LEDs. I can't connect any more. Am I missing something obvious? I've tried various sequences of battery/button but to no avail.
