Project Description

2. By Bluetooth
Device would need to have USB, which would be used for it's own update, and for updating our current device (BRIDGE)
Device would have graphical OLED display(probably it will be 256x64 display) with few function buttons.
On display it would be showing different states (alarms and some other messages) received from our current device, and on the other side it would send different messages to our current device. Display needs to have automatic adjustable brightness depending on the intensity of the light.
