Hi, I want to make a drone with camera. I want to use the low cost OV7670 Camera module
and HC 05 bluetooth module to send the images captured from the camera to the android phone. Is this possible?
Details :
Using Arduino mega 2560, OV7670 cam module, HC-05 bluetooth module
datasheet of OV7670:
The first question would be the distance that you want to transmit over. BlueTooth is not meant for longer distances.
Still images, as in one picture every so often, or moving images such as in Video.
What distances ?
you can use esp32 cam and get bluetooth capability included or use any other esp32 board with cam with more I/Os, don’t understand this forum obsession with overpriced inferior hardware
Only pictures
Distance between 200 - 400m
Search: Google Search
And ESP32 is a better choice, fast processor, plenty of memory, integrated camera, SD card and cheap.
But 400m seems a bit far for its WiFi and Bluetooth.
Use 2.4Ghz LoRa, at 400m+ it can transfer a 64K image in about 2.5 seconds.
And how were you planning to transfer the pictures ?
Radio comms is never going to be 100% reliable, and a single bit error in the image file being transferred could render it useless.
