We are a Mechanical Locks company and we want to develop a Bluetooth controlled smart padlock.
We can develop all the mechanical parts of the lock but need all the electronics and software to be designed for us which includes the PCB Board designing and the Embedded Software for it and also includes the mobile APP to control the lock from the mobile phone.
We have designed some algorithm and some Basic Requirements.
You can get a better idea by reading about the Noke Lock, Master Bluetooth Padlock, eGeeTouch Smart Travel Padlock and Gelilia Smart Padlock.
It'll be great if you can fill in the blanks.
