Hello,
I'm looking for a customized bluetooth shutter that I can program the message/action it sends via bluetooth to a proprietary hardware we have. The application is simple we have a PCB that is connected to doors and receives bluetooth commands with a proprietary hash system to open gates/doors. We want to make a controller that can receive via bluetooth the command we need to send to the gate and the user will be able to send this command using a remote controller much like a selfie shutter but to our hardware. I'm looking for factories that already produce selfie shutters to develop this project.
