I have a string that is 928 characters that I am using to create a qr code for. The issue I am having is that, although the QR code scans fine on Iphone, android devices seem to struggle detect it. I believe this is due to the size of the QR code. I wanted to know if there was a way I could truncate that 928 character string to under 50 characters and then expand it when I use it after scanning the QR Code. Upon researching, I found many QR question and a lot of questions on how to shorten text, but nothing specifically relating to my question.
The QR HTML is:
<qrcode
[qrdata]="qrUrl"
[allowEmptyString]="true"
[attr.ariaLabel]="'QR Code image with the following content...'"
[cssClass]="'center'"
[colorDark]="'#000000ff'"
[colorLight]="'#ffffffff'"
[elementType]="'canvas'"
[errorCorrectionLevel]="'M'"
[attr.imageSrc]="currentUser.imageData ? currentUser.imageData : './assets/default-logo.png'"
[attr.imageHeight]="75"
[attr.imageWidth]="75"
[margin]="4"
[scale]="1"
[title]="'A custom title attribute'"
[width]="300"
></qrcode>
Changing the error correction to L fixed the issue.
I am using parrot ar drone 2.0 and trying see if it detects the oriented roundel. This is a part of my code:
client.config('CAD_TYPE_ORIENTED_ROUNDEL_BW', 12);
client.config('general:navdata_demo', 'FALSE');
and later i have:
console.log('cameraSource:' + d.visionDetect.cameraSource);
console.log('tag_count:' + d.visionDetect.nbDetected);
console.log('tag_type:' + d.visionDetect.type);
But the number of tags and everything remains zero despite the drone moving above the tag.
I am a bit new to node.js so can somebody please tell me what the problem is?
Apparently you need to type all configurations in lower case letters.
so with this configuration it can detect it.
client.config('detect:detect_type', 12);
number 12 corresponds to the black and white oriented roundel.
I have encountered a strange failure when this code runs on my NodeMCU 0.9 board. It is basically getting http code from an API in the following format:
<abbr title="klokken">kl</abbr> 11–12
In this case I want to isolate the 11 and 12 by first removing the first 42 characters which works perfectly fine and then replacing the – with --. When I open a sketch and paste this program in it it runs perfectly fine and returns 11--12 but when I save this program under a random name it is rebuilt and for some reason doesn't replace the characters properly it then returns 11–12.
I have tried to replace different parts of the string when it was rebuilt which worked fine but for some reason I can't seem to either find the index of nor replace the three strange characters.
http.begin(URL_time);
int httpCode = http.GET();
String timerange;
if(httpCode > 0){
timerange = http.getString();
timerange.remove(0,42);
timerange.replace("–", "--");
Serial.println(timerange);
Thus my question is if anyone knows how to work around this issue apart from not saving my code. Feel free to ask me to elaborate on my question when needed.
The string you're receiving is encoded in Windows Latin 1 (ISO 8859-1), and you're (probably) using UTF-8. What you need is to re-encode the string properly.
I know, silly question, but I am not a programmer and really need to known...

Related Anecdote:
My first encounter with a computer was around 1985, in my classroom we had an Apple (Apple ][ probably?). This was one of the main programs that was available. I had learned how to do to in order to define a subroutine. I tried it once, but I couldn't remember the syntax for defining the specifics. And then when I tried to exit the to routine definition context, I couldn't remember how to exit it. The teacher could sense that I was confused, and was coming over to help me. I figured I'd be in trouble for straying beyond the scope of the exercise that I was supposed to be working on, and figured the teacher wouldn't know how to recover either. I panicked and powered off the computer. My first "did you try turning it off and on again?" experience! :)
I need my [[+idx]] tv to start at 0 instead of 1 so I tried this:
[[+idx:decr]] or [[+idx:substract=1]] but it gives me -1 (minus one).
Does anyone know another way to obtain 0?
Thank you
Using this in chunk for getImageList works (at least for me):
[[+idx:decr]]
It gives: 0,1,2,3 ....
P.S. using modx revo 2.3.1
set your template variable default to 0 when you create the variable.
What are you trying to do, your question is vague at best.
UPDATE
ok - what I think will work for you is to write a snippet to do the math... where ever you call the [[+idx]] instead write a snippet
[[!FixIDX? &itemindex=`[[+idx]]`]]
then in your FixIDX snippet just do the math with php and return the corrected index. Though perhaps a custom output modifier would be the better way to go: http://rtfm.modx.com/display/revolution20/Input+and+Output+Filters+(Output+Modifiers)
Though looking at the docs, your code should certainly work - I see no reason for it not to.
