I would like to source a compact BLE board to act as a lock controller developed with with a matching transceiver for use in a fob and an app.
It would toggle the pio and generate a log entry upon receipt of an unlock event from a fob or app. The app would pull the log from the control board and write it to a server. Keys would be generated on the server and passed through the app to the controller and fob. We would need the source released to us for custom development.
I am aware of one developed on the 51822 chip however they will not release the source.
Any suggestions for a developer contact?
