Bk2461 Datasheet Jun 2026

Communication between the host microcontroller (MCU) and the BK2461 is handled via a standard SPI (Serial Peripheral Interface). The datasheet details the timing requirements for this interface, which is crucial for high-speed data throughput. The SPI allows the MCU to configure the radio, read status registers, and write payload data into the TX FIFO or read data from the RX FIFO.
