QUESTION
Right now I am developing web which has ability to connect thermal printer. I am using angular framework, and I successfully connect the thermal printer with USB using library ng-thermal-printer. But I want to my web also being able to connect thermal printer via web bluetooth which is BLE (Bluetooth Low Energy). As far as I know, BLE has specification in term of GATT and has services and characteristics in it.
The progress I did so far, I can connect and send a value to the thermal printer device in a Service and a Characteristic, let's say Service with UUID AS and Characteristics with UUID AC, using my android phone with the help of application named nRF Connect. Targeting Service AS and send hexadecimal value at charateristic AC make me successfully print something on the thermal paper.
But there is a problem. After knowing the right service and characteristic. I implemented it in my project. But, my chrome browser console showed error:
- Origin is not allowed to access any service... and it told me to add optionalServices when requestiDevice()
- After I added Service AS in property optionalServices, the console showed error DOMException: Connection failed for unknown reason. The errors showed both in chrome PC and chrome android.
NB:
- I have enabled Experimental Web Platform features on chrome
- I have enabled Use the new permissions backend for Web Bluetooth on chrome
- I have enabled Allow invalid certificates for resources loaded from localhost. on chrome
- I have enabled Enable new USB backend on chrome
- I have used https.
Additional question. is bluetooth connection that application nRF Connect used different from BLE? if so, why it displays services and characteristics?
...ANSWER
Answered 2021-Jun-14 at 07:34I'd recommend you try sending those hex values directly from the about:bluetooth-internals page and see if you can reproduce the connection error from there as well. See https://web.dev/bluetooth/#tips
If so, check out https://www.chromium.org/developers/how-tos/file-web-bluetooth-bugs to learn how to properly file a chromium bug so that the team can fix the underlying issue.
If not, could you share your JS code so that we can help you diagnose what could be going wrong in your code?
QUESTION
Im using a thermal printer (Hoin POS-58) to print receipts but i dont like the final result due to ugly font styles.
Im setting font-family and font-size in css print media query but as i told you the results are poor.
However, I can see how the selftest page font are much more pretty.
Do you know what font is "Font-A" or how can I set a propper font or configure printer to print the same way than in selftest page?
Im using Ubuntu 18.04 and google chrome.
...ANSWER
Answered 2021-Jun-05 at 12:18The thermal receipt printer can print beautifully at the lowest cost when requesting printing of text with character code.
In that case, the font data held by the printer is used, and it has only a few types of fonts with different character sizes (number of dots).
The font does not have a name like that given on a PC, etc., and is usually named Font-A/Font-B/Font-C.
However, there is no standard for font content and it depends on the vendor and model.
Also, unlike PC fonts, it is not possible to specify the size in 1-point units, and the decoration of characters can only be specified within a poor range.
On the other hand, the print result you got is probably that the application and the print driver have expanded the print content into a bit image and requested the printer to print it as a bit image.
The method of developing and printing on a bit image can produce poor results, such as yours, or you can obtain precise results, such as photographs.
It depends on how beautiful and precise the bit image can be created when creating print data.
There are two directions you can do.
One is to improve the beauty and fineness of the bit image data for printing to be created while keeping the current method.
The other is to stop creating print data as a bit image, to request printing by text in character code, and print contents and printer by the control code supported by the printer (usually ESC / POS original extension). Is to switch to control.
In this case, you will need to change everything from the printer's hardware mode settings to the printer driver to the application's control method.

...ANSWER
Answered 2021-May-28 at 12:08Firstly it's wrong to read a file like this, you don't need to create a new process each time that you want to get the temperature.
Secondly, you may not have the file your are looking for. This is because the /sys/* is a pseudo-filesystem (sysfs) created by the system and it's different drivers. It may be very different from a phone to another.
I found a non-exhaustive list of cpu temperature file.

QUESTION
I've been looking into different API/SDKs that would be best and easiest to integrate with my React Native iPhone app. This is an internal employee app, that once a form is submitted I would like to automatically print out a label from a thermal printer (e.g. Brother QL1110NWB).
Some options I found are:
React Native:
Brother SDK:
Apple AirPrint:
Does anyone have experience with any of these API/SDKs and can recommend best method for easy integration and be able to print directly without interaction?
Thank you!
...ANSWER
Answered 2021-May-17 at 14:08If you can dictate the hardware to make sure it is compatible, then the Brother SDK will have the easiest integration and be transparent to the user.
Apple restricts Bluetooth Classic devices from connecting to iOS unless they are MFi certified, which adds to the price but enables the External Accessory Framework at the OS level. Device manufacturers can then sell a printer that is 'iOS certified' like the Brother QL1110NWB and provide the SDK to use it.
How to use bluetooth classic instead of le
You would need to write a React Native binding for each target device family to use the SDK's OS specific libraries. Brother has an iOS, Android and Xamarin SDK available, but I don't see one for React, so you would need to wrap their iOS SDK with hooks to invoke your print on demand. Before you start, contact Brother support or your sales rep, because they may be working on React Native SDK, or your organization may have enough buying power to request one. Either way, it's a good practice to make this an interface at the base React level so that new printers or platforms can be added just by implementing custom native device adapters.

I am fairly new to Swift and SwiftUI programming and I have come up again a weird issue.
My goal is to read the variable in the text field and have the variable print as a comment once the user has clicked return (oncommit).
I tried to use a single $comment variable but that updates both the Text result as soon as the user is typing in the text field.
My goal is for the user to be able to type in the text field and the variable just appears in the section under the text field: ("Your Comment is:"")

QUESTION
This is a problem concerning stereo calibration and rectification using openCV (vers. 4.5.1.48) and Python (vers. 3.8.5).
I have two cameras placed on the same axis as shown on the image below:
The left (upper) camera is taking pictures with 640x480 resolution, while the right (lower) camera is taking pictures with 320x240 resolution. The goal is to find an object on the right image (320x240) and crop out the same object on the left image (640x480). In other words; To transfer the rectangle that makes up the object in the right image, to the left image. This idea is sketched below.
A red object is found on the right image and I need to transfer it's location to left image and crop it out. The objects is placed on a flat plane 30cm from the camera lenses. In other words; The distance (depth) from the two cameras lenses to the flat plane is constant (30cm).
This main question is about how transfer a location from one image to another, when two cameras are placed side by side, when the images are of different resolutions and when the depth is (fairly) constant. It's not a question about finding objects.
To solve this problem, as far as I know, stereo calibration must be used, and I have found the following articles/code, among other things:
- https://github.com/bvnayak/stereo_calibration/blob/master/camera_calibrate.py
- https://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_calib3d/py_calibration/py_calibration.html
- https://python.plainenglish.io/the-depth-i-stereo-calibration-and-rectification-24da7b0fb1e0
Below are an example of a calibration pattern that I used:
I have 25 photos of the calibration pattern with the left and right camera. The pattern is 5x9 and the square sizes is 40x40 mm.
Based on my knowledge, I have written the following code:
...ANSWER
Answered 2021-Apr-26 at 19:02I solved this problem by using the following openCV functions:
cv2.findChessboardCorners()cv2.cornerSubPix()cv2.findHomography()cv2.warpPerspective()
I used the calibration plate at a distance of 30cm to calculate the perspective transformation matrix, H. Because of this, I can map an object from the right image to the left image. The depth has to be constant (30 cm) though, which is a bit problematic, but it is acceptable in my case.
Thanks to @Micka for the great answers.
