Creating a Wireless remote for Nikon Camera using Esp8266

The Nikon DSLR camera I own does have a Bluetooth connection, but unfortunately it is of no use. You cannot trigger shots from Bluetooth. Also u can only share photos of low resolution across Bluetooth. What a shame!!! I also want a time lapse option which is absent in the camera. There is a WiFi option, but have to invest a lot more money to buy the WiFi adaptor. Fortunately it has an IR interface. So I thought of creating my own triggering device (like the ML-L3) which works over WiFi so that I can remotely trigger the shutter and also take time lapse pics.
