TimeoutException Error

[GuilhermeCarvalho1144]

I'm getting this error whem the camera is rolling for a while:

File "site-packages\pypylon\pylon.py", line 3222, in RetrieveResult _genicam.TimeoutException: Grab timed out. The acquisition is not started. : TimeoutException thrown (file 'instantcameraimpl.h', line 1031)

The code I'm using is the following:

        print("using %s @ %s" % (dev_info.GetModelName(), dev_info.GetIpAddress()))
        camera = pylon.InstantCamera(tl_factory.CreateDevice(dev_info))
        break

    raise EnvironmentError("no GigE device found")

The camera I'm using is the Basler Racer raL4096-24gm.

You are using the hardware trigger. Is it sitting idle? This will cause a timeout.

Does this code can be used for grab a simple photo? I mean leaving the main while loop as soon as you get a succeded image?

import numpy as np
NULL_ARRAY=np.ndarray(shape=(0,0))

def grab_basler_photo():
    array=NULL_ARRAY
    try:
        from pypylon import pylon
        camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice())
        camera.Open()

        # Grabing Continusely (video) with minimal delay
        camera.StartGrabbing(pylon.GrabStrategy_LatestImageOnly)
        converter = pylon.ImageFormatConverter()
        converter.OutputPixelFormat = pylon.PixelType_BGR8packed
        converter.OutputBitAlignment = pylon.OutputBitAlignment_MsbAligned

        while camera.IsGrabbing():
            grabResult = camera.RetrieveResult(5000, pylon.TimeoutHandling_ThrowException)
            if grabResult.GrabSucceeded():
                image = converter.Convert(grabResult)
                array = image.GetArray()
                camera.StopGrabbing()
                camera.Close()
                return array
            else:
                pass
            grabResult.Release()
        camera.StopGrabbing()
        camera.Close()

    except Exception as Err:
        array=NULL_ARRAY
        logger.error('errors with pypylon\n'+Err)

    return array
