I'm using a batch file on a Windows Vista PC to control and download media from a GoPro Hero 3+ Black camera. Thanks to the WiFi hacking ingenuity of https://github.com/KonradIT/goprowifihack, you can curl URLs to tell the camera to start and stop recording, change modes, etc. Then I can use wget to download the files from the camera to my hard drive.
My issue is that after about 9 runs through my loop or so (it varies) I lose connection:
curl: (7) failed to connect to 10.5.5.9 port 80: Timed out
Is there something I'm doing that overloads the connection?
Here's just the code that I think is relevant for my issue:
echo off
setlocal enabledelayedexpansion
REM turn on the camera
curl http://10.5.5.9/bacpac/PW?t=password^&p=%%01
timeout 10 /nobreak
REM delete all previous files
curl http://10.5.5.9/camera/DA?t=password
timeout 10 /nobreak
REM begin recording video
curl http://10.5.5.9/bacpac/SH?t=password^&p=%%01
timeout 60 /nobreak
REM stop recording
curl http://10.5.5.9/bacpac/SH?t=password^&p=%%00
for /l %%a in (1,1,1000) do (
REM download video files
wget -b -r -A .MP4 -nH --cut-dirs=3 http://10.5.5.9:8080/videos/DCIM/100GOPRO/
timeout 10 /nobreak
REM change to timelapse mode
curl http://10.5.5.9/camera/CM?t=password^&p=%%03
timeout 5 /nobreak
REM begin timelapse
curl http://10.5.5.9/bacpac/SH?t=password^&p=%%01
timeout 200 /nobreak
REM end timelapse
curl http://10.5.5.9/bacpac/SH?t=password^&p=%%00
REM download JPEGs
wget -b -r -A .JPG -nH --cut-dirs=3 http://10.5.5.9:8080/videos/DCIM/100GOPRO/
timeout 10 /nobreak
REM change to video mode
curl http://10.5.5.9/camera/CM?t=password^&p=%%00
REM wait for awhile until the next measurement
timeout 200 /nobreak
REM delete all files (since enough time has elapsed for them to be downloaded)
curl http://10.5.5.9/camera/DA?t=password
timeout 10 /nobreak
REM begin recording video
curl http://10.5.5.9/bacpac/SH?t=password^&p=%%01
timeout 60 /nobreak
REM end recording video
curl http://10.5.5.9/bacpac/SH?t=password^&p=%%00
)
endlocal
The issue seems to be that running wget in the background while also recording more media overloads the camera and causes it to shut down the Wifi.
Removing the -b parameter from wget to avoid wget running in the background fixes this issue.
