Byte communication between RPI4 and Wavesharemodule via uart

Asked 2022-Mar-12 at 17:30

I have bought the wavesharebarcodereader module (https://www.waveshare.com/wiki/Barcode_Scanner_Module) and managed that it decodes codes and sends the data to the rpi. Now i try to use it in command Mode where i can trigger the scanning by sending a byte array.

In my understanding this is an Array of Hexadecimal bytes so i need to suffix each byte with a 0x so i wrote echo "0x7E 0x00 0x08 0x01 0x00 0x02 0x01 0xAB 0xCD" > /dev/serial0 and the voltage of the tx pin drops for a moment as if it would send but the device doesnt react or answer. I also tried without the quotes or single quotes or without the 0x suffix but the device doesnt "understand" it and doesnt react. Im sure the cabeling is correct and i tested the pins by connecting rx to tx straight and that works too. The barcodereader does work on 3.3V pins too so that is not the problem. I also tried sending the bytes with an arduino but the reader doesnt respond to that either. Sadly all the Documentation on the Reader is this: https://www.waveshare.com/w/upload/d/dd/Barcode_Scanner_Module_Setting_Manual_EN.pdf

Ive been stuck on this problem super long because im very new to uart bytes so any help would be appreciated.

Alright i figured it out: i needed to use the command: printf "%b" '\x7E\x00\x08\x01\x00\x02\x01\xAB\xCD' > /dev/serial0 and that worked

Cannot get location property from an object i get through an api call

Asked 2021-Nov-01 at 16:16

So im getting a task by its id, im scanning a barcode i get the id and i get the data of the task, but for some reason i cant setLocation to resultData. Location, when i log resultData i get all the data of the task, when i log resultData.location i get the location object, but when i want to setLocation(resultData.location) i just get an empty object logged - note in use state default state is {}, if i just set the default state to nothing it returns undefined in the console.

ANSWER

Answered 2021-Nov-01 at 16:16

The real reason is the execution of setState is asynchronous. So when you console.log the state just after receiving the api response, You can not see the updated state immediately. For more detail explanation, you can checkout this post.

It seems you need the location variable in distance function only, so just return the location in loadTask function and pass it to the distance function is fine.

In your sample code, the name of the button is btnQCRead, however your method to handle the click event is named btnRead_Click. The AutoEventWireup is looking for btnQCRead_Click, which won't match your method btnRead_Click. The same is true for btnQCGenerate and the unmatched method btnGenerate_Click which will need to be similarly renamed btnQCGenerate_Click.

You cannot. if you look at the source code you will see that what it does is call a java app with the provided path (Specifically com.google.zxing.client.j2se.CommandLineRunner).

If you need to pre-process your image then you will have to save it somewhere and pass the path to it to your library

How can I prevent my Android Location App from crashing on first time run?

Asked 2020-Jul-16 at 12:26

I have created an Android App which opens a Map Fragment and is to create 2 markers:

Marker 1 is the current location (which i believe may be the cause of the problem)

Marker 2 which gets the coords(LatLng) passed from a previous Activity

My problem is that when I run the app for the first time it crashes ... stops responding I have made sure all the permissions and manifest file is correct. But i have made the following observation : After the app crashes if i open Google Maps close everything and run the app again it works fine.

The following error message is generated:

2020-07-16 09:51:16.363 3833-3833/com.notbytes.barcodereader E/AndroidRuntime: FATAL EXCEPTION: main Process: com.notbytes.barcodereader, PID: 3833 java.lang.NullPointerException: Attempt to invoke virtual method 'double android.location.Location.getLatitude()' on a null object reference at com.notbytes.barcodereader.MainActivity2$4.onSuccess(MainActivity2.java:197) at com.notbytes.barcodereader.MainActivity2$4.onSuccess(MainActivity2.java:192) at com.google.android.gms.tasks.zzn.run(Unknown Source) at android.os.Handler.handleCallback(Handler.java:751) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6077) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:756)

Any help or assistance will be greatly appreciated.

Sometimes the getLastLocation() method might return null, because the fused location provider doesn't update the location cache after the device is restarted. If getLastLocation() returns null unexpectedly:

Location is turned off in the device settings. The result could be null even if the last location was previously retrieved because disabling location also clears the cache.
The device never recorded its location, which could be the case of a new device or a device that has been restored to factory settings
Google Play services on the device has restarted, and there is no active Fused Location Provider client that has requested location after the services restarted. To avoid this situation you can create a new client and request location updates yourself. For more information, see Receive Location updates.

But in your case, I guess you have not added any check before getting latitude and longitude.

Below is a sample code of how to get and set location.
