A developer is responsible for designing, implementing, and managing wireless communication systems using the RF transceiver. They primarily work on the . GHz IEEE .. standard, focusing on low-rate wireless personal area networks (LR-WPANs). Their tasks include programming microcontrollers for the , troubleshooting and optimizing wireless communication protocols, and ensuring the efficient performance of the transceiver. They also handle the integration of the into various devices and systems, such as IoT devices. They must have a deep understanding of hardware-software interfacing, embedded systems, and wireless communication principles.
