Abstract: A method and a device are provided for waking up a MCU. The method includes: determining whether a second MCU is in a deep sleep state, when a first MCU triggers a communication event of transmitting data to the second MCU; and when the second MCU is in the deep sleep state, sending an interrupt wakeup signal to the second MCU via a wakeup pin connected between the first MCU and the second MCU, so as to wake up the second MCU.

Abstract: The present disclosure provides a method and a device for processing PWM data, so as to reduce the size of the PWM data. The method includes: dividing pulse widths in the PWM data into at least one pulse width group; determining a convergence pulse width for each of the at least one pulse width group, herein each of the at least one pulse width group converges around a same pulse width, respectively; replacing each of the at least one pulse width group with the corresponding convergence pulse width; and representing the PWM data by using the convergence pulse widths. Through the technical solution, the size of the PWM data may be reduced, transmission speed of the PWM data may be improved, and the space for storing the PWM data may be decreased.

Abstract: This disclosure relates to a message transmission method, a message reception method and corresponding apparatuses and storage mediums. The message transmission method may be performed by a first Bluetooth device and may involve generating, by a processor of the first Bluetooth device, a beacon frame message based on an intended interaction purpose with a second Bluetooth device, wherein the beacon frame message contains one or more fields indicating the interaction purpose, and broadcasting the beacon frame message using a Bluetooth communication interface of the first Bluetooth device. By including one or more fields indicating the intended interaction purpose within the beacon message frame, the first Bluetooth device and a second receiving Bluetooth device may be able to interact with one another without having to first establish a connection there between, thereby overcoming limitations of traditional Bluetooth communication schemes.
