sos | Tools and configurations I use most in my everyday

I want to get/identify the object who has the Id "C003", for example, to print all data of that object.

I receive the id typed with cin and store in a string variable.

I've been reading many webpages and YouTube tutorials that use function find() or find_if(), but those examples use only numbers, so the third parameter is just a number, like 2.

In my case, I have a list with objects, and my conditional is this:

In TTN they are no longer supporting large decoders.

I know what the decoder needs to be in TTN, it is in my DECODER function, but dont know how to execute it in the function node.

If you use inject Payload [1,2,3] RAW, it injects the raw payload that is msg.payload.payload.uplink_message.frm_payload into the decoder.

The DECODER needs to decode the raw payload and output it in msg.payload.uplink_message.decoded_payload

If you use inject Payload [1,2,3] Decoded in the flow you see how the end result needs to look like and the decoded msg.payload.uplink_message.decoded_payload

I am still learning JavaScript.

The code in the function node

I am trying to build a view programatically in android, and I can't seem to reach my end goal.
Here is the design

and here is what I have

here is the code

I am currently trying to make a .wav file that will play sos in morse.

The way I went about this is: I have a byte array that contains one wave of a beep. I then repeated that until I had the desired length. After that I inserted those bytes into a new array and put bytes containing 00 (in hexadecimal) to separate the beeps.

If I add 1 beep to a WAVE file, it creates the file correctly (i.e. I get a beep of the desired length). Here is a picture of the waves zoomed in (I opened the file in Audacity): And here is a picture of the entire wave part:

The problem now is that when I add a second beep, the second one becomes completely distorted: So this is what the entire file looks like now:

If I add another beep, it will be the correct beep again, If I add yet another beep it's going to be distorted again, etc. So basically, every other wave is distorted.

Does anyone know why this happens?

Here is a link to a .txt file I generated containing the the audio data of the wave file I created: byteTest19.txt

And here is a lint to a .txt file that I generated using file format.info that is a hexadecimal representation of the bytes in the .wav file I generated containing 5 beeps (with two of them, the even beeps being distorted): test3.txt

You can tell when a new beep starts because it is preceded by a lot of 00's.

As far as I can see, the bytes of the second beep does not differ from the first one, which is why I am asking this question.

If anyone knows why this happens, please help me. If you need more information, don't hesitate to ask. I hope I explained well what I'm doing, if not, that's my bad.

EDIT Here is my code:

I am new in kivy, I created a form that uses 2 spinner, the 1st spinner contain a list of values that when selected it will call a function from .py file and change the values of the 2nd spinner. But whenever i select a value from the 1st spinner the "AttributeError: 'super' object has no attribute 'getattr'" is displayed. I've tried so many things but couldn't make it work, Please any attempt is appreciate.

My .py file:

i'm trying to extrapolate a json if a string is contained. My json is this:

I have drop down menu with 2 arguments, title and id. drop down selected item will show just title arguments but i want to pass title's id to the another widget like future builder, so any idea?

Im trying to get realtime location with pointing on the Google Map. Currently i successfully get the latitude and longitude in realtime and it will update everytime to a getter, setter class called sosrecord.getLatitude() and sosrecord.getLongitude(). I want to point the google map based on the updated latitude and longitude. But everytime when i put the getter on the LatLng latLng = new LatLng(sosrecord.getLatitude(), sosrecord.getLongitude()); it will return me Null and eventually crash the app due to java.lang.NullPointerException: Attempt to invoke virtual method 'double java.lang.Double.doubleValue()' on a null object reference It should point the current location when user click on a button. Sorry if the code sample below is messy, hope someone could help me with this issue. Thanks.
