hi,
i'm tryting to add a small camera to my esp controlled robot, but i dont seem to be able to get a video stream trough .
let me clarify , i have an esp sending serial to an arduino used to controll the motors but for the interface i have a small (ugly) web page running on my esp . My thought was to use the esp as a small host/router to connect the camera to and my cellphone/laptop/homenetwork/ wathever to but .... i dont seem to be able to host the video stream on the esp when i connect the camera ( i think it's connecting) to the ESP network . it does work when i connect the esp to my home network ant the camera also to the home network. " dont worry i drew(?) a litle diagram to make it more clear .
So i was hoping someone could point me to the right direction .
i also am sorry if the spelling and grammar are all over the place .
