QUESTION
I am trying to get my robot to communicate with my PC via sockets by using local IP addresses on my own home network (not devices outside my network). The robot is acting as the server and my own PC is acting as the client/host. I don't really know what ports are open on my robot but I do definitely know that port 22 on the robot is open (which is the SSH port). The robot is a lego EV3 robot apart from it has had some ev3python software put onto it. When I run my program I am getting the following error on the server (my robot):

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((hostIPAddress,22))#22 is the port number I am using. (THIS IS ALSO THE LINE WHERE THE ERROR IS COMING FROM)
s.listen(backlog)

QUESTION
There are 8 motors and I am monitoring their speeds. I have a dictionary through which I am iterating and then I am calculating the difference in the speed with the individual retrieved speeds.
- Then I have to compare if the change is less than the maximum values for each motor (which is there in the speeds list for each motor).
- Currently what is happening is it is calculating the difference only for the last speed
- Retrieved speeds dictionary looks like {1: 8490, 2: 7920, 3: 8460, 4: 7890, 5: 8460, 6: 7950, 7: 8430, 8: 6720}

QUESTION
I have 2 xml messages that are nearly similar but do have some dedicated elements. now I want to combine these to messages and create a "flexible" xml schema for it so I can validate it before processing.
The idea is to have a common structure where all the fields are defined that are in both xml messages and then 2 dedicated parts for the fields that differ. And then somehow determine which message is being received and then using the common and correct dedicated part of the xml schema to validate.
a simple example is shown below. Depending on the TransportType (which can be car or boat) the xml message will contain 3 elements. 2 elements (make and model) are common for both and the other 2 (airbags and motorized) are specific depending on the choice.

Answered 2021-Jun-07 at 14:16Unless you're prepared to use an xsi:type
attribute in the source document to distinguish the different cases, this can't be done in XSD 1.0. In XSD 1.1 you can do it using assertions - though if you can make TransportType
an attribute rather than an element, you can do it using conditional type assignment, which is a much neater solution as it's custom-designed for this job.

QUESTION
I have following problem, I want to add a regular list view into the extended part of an extendable list view, I have tried to do it with following code:
...ANSWER
Answered 2021-Jun-05 at 21:37Well to fix the Overflow you can wrap your widget in a SingleChildScrollView
, anytime you paint more content than the available space on the screen you should use this or a ListView to be able to scroll.
As for the checkbox alongside each tile you were painting the checkbox before the ListView.builder
that created each expandedValue
so it was just created once for the listTile that contained the listivew and not for each item. Constructing the checkbox inside the listview.builder did the trick for that.
I also added a boolean property to the expandedValue
class to be able to check each item individually (IDK if this is the behavior you were seeking).
QUESTION
I have a table called treeview with a id, name, assettype and parent.
I have another table which is called events with a id and treeid.
a treeview instance can have events and then treeview.id = events.treeid.
I made a query to show all the events and show the treeid, sensor name and parent. But I want to show the machine name as well.
The problem is that my "machine" name and "sensor" name are in the same column but machine names have assettype = 2 and sensor names have assettype = 3 or 4.
For example in the first row the "Motor NDE Vertical" (sensor) has parent "1191" which is "Sidewinch PS" (machine) but it's not showing up.
I guess I need to implement the "WHERE assettype = ..." somewhere but I can't find where.
Can anyone help me with this please?

QUESTION
I'm trying to send data from my android app to an esp32 over bluetooth (BLE) but i can't find the proper way to do it. All i can do for now is scan and find ble devices. My arduino code is working as i want (it receives the data properly) because i used another app which let me send data to ble devices so i know the arduino code is fine.
I've been searching for days here and google how to achieve it but i still stucked in it. This is my code for now:

...ANSWER
Answered 2021-May-31 at 09:00In order to get this working, I would do the following if I was you:-
Part A: Get this working with an existing Android app (e.g. nRF Connect - maybe you've already done this part)
- Download and install nRF Connect app from the play store.
- Launch nRF Connect app and scan for devices.
- Connect to your ESP32 if it was found.
- Browse the GATT table and find the UUID and handle of the characteristic that controls the ESP32. This is important as it will be used in Part B.
- Once found, try to write the values 0, 1, 2, 3, and 4 to this characteristic and ensure that everything is working.
If there are parts above that are new to you, please have a look at the links below. If you've already successfully done all of the above, then move to Part B:-
- nRF Connect For Mobile - Get Started
- Bluetooth Low Energy Characteristics - A Beginner's Guide
- Introduction to BLE - GATT
Part B: Get this working using your Android app:-
- Similar to the nRF Connect app, your app needs to scan and connect to the ESP32. You can find examples on how to do this here.
- Once you are connected, you need to browse the GATT Table and find the right characteristic. You can find examples for this here.
- Once you find the right characteristic and its handle (this is the one you noted in step 4 above), proceed to write values to this characteristic. You can find examples here, here and here.
If all of this is in place and it is still not working, here are things to check:-
- Are you waiting for the GATT write completion callback? Also check this.
- Are you using the right Android write operation?
- Are you maybe using reliable writes instead of normal write?
- Are you sending integer data instead of string data? The app expects integer data in order to work properly.
You can find examples and explanations about the steps above in the links below:-
