The customer wants to implement a wireless charging feature in one of his existing Bluetooth headsets. Engibrains provided wireless charging functionality to the standard battery pack along with a communication link between the PC and the Bluetooth headsets for data transfer, debugging, and firmware upgrade. Our firmware engineers have designed and developed the complete firmware of the wireless power along with the integration of multiple sensors. We also carried out power optimization by implementing low-power mode features. Our hands-on experience with NFC Wireless Charging ecosystems like NFC reader/writer, MCU, and communication protocol helps us to provide an optimized and accurate wireless power transfer solution. The Engibrains QA team performed rigorous integration and white box testing to make SW more reliable and stable. The QA team also identified extensive 150+ test cases and automated them to ensure the quality of the SW developed.
