The customer’s device originally used a separate microcontroller and Bluetooth chip.
At first glance, a common solution – but with a lot of untapped potential.

Our solution:

We redesigned the electronics and firmware – instead of two separate chips, we used a microcontroller with integrated Bluetooth.

• Firmware redesign and optimization

• Hardware redesign

• Optimization of communication with the mobile app on the new microcontroller
