QUESTION
I'm have some project, realtime sending RSSI and MAC of Bluetooth Low Energy. I want try using http protocol, and i found OkHttp library. But when i run with OkHttp, my software crash.
My error
...ANSWER
Answered 2022-Apr-02 at 04:40The error is caused due to execution of network request on main thread (a.k.a. UI thread). In general, thread blocking operations (like file read, network requests) are prohibited on main thread. This is done to avoid App Not responding error.
In your mainActivity.java, since BroadcastReceiver#onReceive is executed on main thread. (Ref: https://stackoverflow.com/a/5676888/5309486 ). And inside this onReceive function, you are trying to make the network request.
Just, use handler and post the network call to background thread (or any other thread) and that will fix your issue.
QUESTION
Maybe someone can help me out because I have a really tricky situation with Bluetooth LE using WinRT on Windows 10 (like supposed here: Bluetooth Low Energy in .Net (C#)).
I need BLE within a Win32 classic desktop application.
Our code is running in a 32 Bit frame application using the .NET runtime (v4.0.30319, .NET Framework 4.6.2). I was able to manage all the other issues (strong naming some NuGet assemblies (Shiny.BluetoothLE), running BluetoothAdapter.GetRadioAsync() in a 64 Bit COM surrogate DLL when running on 64 Bit Windows) but now I am totally stuck with this and here’s where:
The problem occurrs when executing var result = await gattDeviceService.GetCharacteristicsForUuidAsync(uuid, BluetoothCacheMode.Cached); see here https://docs.microsoft.com/de-de/uwp/api/windows.devices.bluetooth.genericattributeprofile.gattdeviceservice.getcharacteristicsforuuidasync?view=winrt-20348.
When getting the read characteristics, the result.Status is GattCommunicationStatus.Success and the result contains the desired characteristic.
But of course I also need to get the write characteristic and I am ALWAYS getting GattCommunicationStatus.AccessDenied!
Because of that the result contains NO characteristic.
Has anybody a clue why is that? I really need help here because I am kinda lost right now…
I also tried to set AccessPermission via registry like supposed here but no luck at all…
PS: I use Windows 10 SDK Kit Build 20348 and like stated above it is a C# .NET Framework 4.6.2 project and all our assemblies are strong named because of using GAC. If I am missing anything don’t hesitate to contact me.
...ANSWER
Answered 2022-Mar-26 at 15:26For anyone who stumbles over the same stupid issue...Here's the solution:
On Windows, using .NET Framework 4.6.1+ and the WinRT libraries inside a Non-UWP application, you can only call ONCE for getting the characteristics, no matter if you call for all at once via gattDeviceService.GetCharacteristicsAsync(BluetoothCacheMode.Uncached) or for a specific one via gattDeviceService.GetCharacteristicsForUuidAsync(uuid, BluetoothCacheMode.Cached).
Any subsequent calls will fail with GattCommunicationStatus.AccessDenied...
So my solution now is to retrieve all characteristics at once and filter them locally.
That did the trick! Anyways, this is so stupid...It wasted a lot of my time now!
As it seems, I also do not need to set any AccessPermission via registry.
PS: I will call out to you, if I stumble over another tricky situation, just to let you guyz know.

QUESTION
I'd like to confirm the battery usage of an app I am developing on iOS, specifically on Xcode 13 and iOS 15. (Note: This app previously showed no issues with battery usage on previous versions of iOS.)
Previously, it seems that there were two ways to gather energy usage information:
#1. On the device under Settings > Developer > Logging
- As per Apple's documentation described in the section titled "Log Energy Usage Directly on an iOS Device".
- However, on iOS15, I can't find any options for logging under Developer or anywhere under settings even when searching.
#2. Profiling via Instruments using the "Energy Log" template
- As per the same documentation from Apple described in the section "Use the Energy Diagnostics Profiling Template".
- While it is still available in Xcode 12, this template is missing in Xcode 13. Naturally, it's also not possible to profile an iOS15 device with Xcode 12.
Digging through the Xcode 13 release notes, I found the following:
Instruments no longer includes the Energy template; use metrics reporting in the Xcode Organizer instead. (74161279)
When I access the Organizer in Xcode (12 or 13), select an app and click "Energy" for all versions of the app, it shows the following:
Apple's documentation for "Analyzing the Performance of Your Shipping App" says:
"In some cases the pane shows “Insufficient usage data available,” because there may not be enough anonymized data reported by participating user devices. When this happens, try checking back in a few days."
Well over a year into production and having sufficient install numbers, I have a feeling that waiting a few days might not do much.
I would like to determine if this is a bug in my app or a bug in iOS15. How can energy usage data be gathered using Xcode 13 on iOS 15?
...ANSWER
Answered 2022-Feb-23 at 00:43After contacting Apple Developer Technical Support (DTS) regarding this issue, they provided me with the following guidance.
Regarding "insufficient usage data available" for energy logs accessible via the Xcode organizer:
DTS indicated that they do not publish the thresholds for active users and usage logs would be expected to be present if you have more that a few thousand active users consistently on each version of your app. If your app meets this criteria and still does not show energy logs, DTS recommended opening a bug report with them.
Regarding how to collect energy log data for your app:
DTS recommended using MetricKit to get daily metric payloads. Payloads are delivered to your app every 24 hours and it is then possible to consume them and send them off device.
The instantiation of this is vey basic and can be as simple as:

I have tried different for loops trying to iterate through this JSON and I cant figure out how to do it. I have a list of numbers and want to compare it to the "key" values under each object of "data" (For example, Aatrox, Ahri, Akali, and so on) and if the numbers match store the "name" value in another list.
Example: listOfNumbers = [266, 166, 123, 283]
266 and 166 would match the "key" in the Aatrox and Akshan objects respectively so I would want to pull that name and store it in a list.
I understant this JSON is mostly accessed by key values rather than being indexed so Im not sure how I would iterate through all the "data" objects in a for loop(s).

Answered 2022-Jan-20 at 08:38You simply iterate over the values of the dictionary, check whether the value of the 'key' item is in your list and if that's the case, append the value of the 'name' item to your output list.

QUESTION
I've started to write a physics engine but became stuck on some physics of resolving collisions. Let's say I have this situation:
I.e. body B is going towards body A at the speed of 1 space units/time unit. Both A and B have the same mass of 1 unit. Let's consider a completely elastic collision.
I've read in a book (Game Physics Engine Development) that an impulse-based approach can be used to resolve the collision (i.e. find out the linear and angular velocities of both bodies after the collision). As I understand it, it should work like this:
- When the bodies collide, I get the point of the collision and the collision normal.
- At the point of the collision I consider only two points colliding in the direction of the normal (the points at which the bodies are touching, i.e. I ignore the shapes of both bodies) and I compute the new velocities of these two colliding points (this is easy to do, there is a simple formula found e.g. on Wikipedia).
- I find an impulse such that when applied to both bodies at this point it achieves the computed velocities for these two points.
Now the problem arises when I consider that from a physical point of view both momentum and kinetic energy need to be conserved. With these constraints in mind there is seemingly no solution, because:
When B collides with A, B should come to complete stop and transfer all its momentum and kinetic energy to A, according to elastic collision formula. In order for linear momentum to stay conserved, A then has to start linearly moving left at the same speed as B was before the collision (as they have the same mass). So now A has the same kinetic energy as B had, which however means that A cannot come into rotation because that would add additional kinetic energy to it (as rotating adds kinetic energy as well as linear motion), breaking the conservation of kinetic energy. Nevertheless, the physically correct solution IS for A to both move linearly to the left AND rotate as B colliding at this location exerts torque (and I've also checked real life object behave this way). Note that we cannot take away some energy of A's linear motion and add it to the rotation as that breaks the conservation of linear momentum.
The only "real" solution is that B doesn't come to complete stop and keeps some momentum while A will be both moving left and rotating. But this doesn't seem to be doable with the impulse-based approach that only takes into account the two colliding points, the elastic collision formula simply say the point at B should come to stop and as B cannot receive any torque (the collision happens in its middle), the only way to fulfill this is for B to stop moving.
So is there something I missed? Is the impulse-based approach just not physically correct? I appreciate any insight and suggestions on how to correctly resolve the collision. Thanks!
...ANSWER
Answered 2021-Nov-29 at 18:23The formulas that you're looking at are for the collision of two point masses. Point masses can't have angular momentum, and so the formulas have no room for that term.
You have to go back to first principles.
Suppose that an edge collides with another body at a point (think corner hitting an edge). Then a specific impulse is imparted at that point, in a direction normal to the edge. (Any other direction would have required friction, which would make this a non-elastic collision.) The opposite impulse is imparted to the other body, along the same vector. Imparting opposite impulses to both bodies is sufficient to guarantee both conservation of momentum and angular momentum. But conservation of energy is going to take some work.
Next, what happens when we impart that momentum? As this physics answer says, we impart momentum as if the impulse happened to the center of mass. We impart angular momentum equal to the cross product of the impulse and the moment arm (the vector describing how much the impulse misses the center of mass). This will cause the body to start rotating at a rate of the impulse divided by the moment of inertia.
You get kinetic energy from the motion of the center of mass, but also kinetic energy from its rotation.
So in your 2-D collision you now have the following facts:
- The mass of each body.
- The velocities of each body.
- The moment of inertia of each velocity.
- The angular velocity of each body.
- The moment arm of the line of force for each body.
You can now calculate the kinetic energy of the whole system, as a function of the magnitude of the specific impulse. Unlike the point mass, ALL of these factors play into it, making the equation complicated. However, like the point mass, you'll get a quadratic equation with 2 solutions. One solution is 0 impulse imparted (representing the system before the collision), and the other is your answer afterwards. Complete with changes to the momentum and angular momentum of both systems.

By default, Structured Streaming from file based sources requires you to specify the schema, rather than rely on Spark to infer it automatically. This restriction ensures a consistent schema will be used for the streaming query, even in the case of failures.
QUESTION
I was trying to understand basics of Bluetooth. I have few queries regarding the scanning and advertising of classic and low energy Bluetooth.
Is EIR data (classic Bluetooth extended inquiry response) and AD data (Bluetooth low energy scan response) read from GAP profile. Where is data from GAP profile stored? Is it on host or controller?
Is there a different GAP profile for classic and different GAP profile for LE ?
When we enable advertising (low energy) using
hcitool cmdor enable discoverable mode (classic Bluetooth), how does controller get all the advertisement information (scan response/ extended inquiry response)? Is it stored on controller?As mentioned in Bluetooth Specification 4.2 section 7.8.8 LE Set Scan Response Data command can be used to provide data for scanning packets. Is this different than GAP ?
Is Gatt Server running before connection is formed ? If not, then how is GAP profile (used for advertising) relevant before connection ?
Can same fields (e.g. device name) from EIR data and AD data be different ?
ANSWER
Answered 2021-Sep-20 at 15:11Yes, both EIR and AD elements are defined by the GAP profile. This is managed in the host.
No, the same GAP profile is applicable to both classic and BLE. However, a device can support either one or both. What I mean by this is that if you have a Classic-only device, then the qualification will be against the classic GAP profile, while if you have and LE-only device, then the qualification will be against an LE-only GAP profile. In other words, in terms of Bluetooth qualification both the GAP profiles appear to be separate, but on the device itself it is one GAP profile.
Theoretically, GAP-related information is managed on the host layer, and this is then passed to/from the lower layers (see figure from Bluetooth Core Specification below). The controller then takes the information and sends it out in the packet format specified for EIR/AD data by the Bluetooth specification.
- This depends on what you mean by GAP? To avoid confusion, GAP can be a service sitting in your GATT table, but this is not exactly the same as the GAP profile. The GAP service that sits in the GATT table is a subset of the GAP profile in that it contains some information about the GAP profile but is not a 1:1 direct reflection. The Scan Response data itself is defined by the GAP profile, but it is usually not included in the GAP service. Below is a list of all of the mandatory/optional fields for the Scan Response Data (SRD). You can find this and more information in the Supplement to the Core Specification.
Yes, the GATT server (also known as GATT table) should be formed before a connection is made. However, the GATT table can be updated when a connection has already been made. Again in this case I believe you are referring to the GAP service which is slightly different from the GAP profile.
No, fields that are the same in the EIR/AD data should have the same value. This is reflected in the description of the device name in Core Bluetooth Specification v5.3, Vol 3, Part C, Section 3.2.2.1.1:-
A BR/EDR/LE device type shall have a single Bluetooth Device Name which shall be identical irrespective of the physical channel used to perform the name discovery procedure.
If you haven't done so already, I highly recommend reading the Bluetooth Core Specification v5.3, Vol 3, Part C (page 1230) - GENERIC ACCESS PROFILE, as it will have answers to all of these questions and more.
