Hi Andrey, Thanks for the help.
After calling "wget http://192.168.0.9:8081/trig/pointers"; how can I download the corresponding image frame ? Calling the page did not trigger the flash device. I should check the voltage input. The voltage converter works because I saw several flash lights once I plugged the cable (it must be a capacitor discharging). It was not synchronized with the camera. Is it possible to save the trigger settings in order to reload them after reboot ? Regards.
