Looking for someone to build a BLE circuit, firmware to send commands to a mobile phone via GATT profile. Must have experience in circuit development and enclosure design
Circuit, Firmware, enclosure, and adjustable mount
5 button inputs, must be able to hold a coin cell battery, micro LED to distinguish between ON/low battery, button being pressed.
Enclosure must be 25mm in radius.
Mount must have an adjustable band to wrap around multiple size cylendars.
Timeframe is 1 month.
- I will not have multiple milestones. Payment will only be released once I have a working product. (No exceptions! This is due to past experiences where freelancers dragged the project on for more than 12 months even though the freelancers promised a 3 month delivery and never finished the project and lost a significant amount of money)
Once the project is completed, I will need enough time to produce the product unless you are able to produce the product for me.
Looking to have a finished product as soon as possible!
The device/enclosure must be 35mm - 40mm
