CW32W031 CAD Application Reference Application note
●The RF section of the CW32W031 supports CAD interrupt. After entering STB3 from DeepSleep, enabling the CAD function and entering RX mode, the CW32W031 will detect if there is a ChirpIOT ™ signal in the channel, and if so, set the CAD-IRQ high, the MCU kernel can detect if the CAD-IRQ signal is pulled high for a certain period of time to determine if there is a ChirpIOT ™ signal in the channel.
●The user can detect the CAD-IRQ signal via the GPIO11 port, the signal detection process is as follows:
