Embodiment Construction

[0034] As mentioned in the background, most of the Bluetooth low energy devices are in standby mode. In this mode, the power consumption of some components in the Bluetooth low energy device accounts for a large proportion. If this part of power consumption can be saved, the power consumption of the entire chip will be significantly reduced as a whole. To this end, the application proposes a method for controlling specified components in a Bluetooth low energy BLE chip. The method can significantly reduce the power consumption of the Bluetooth low energy device in the standby mode, thereby improving its battery life.

[0035] like figure 1 As shown, it is a schematic flow chart of a control method for a specified component in a Bluetooth low energy BLE chip proposed in the embodiment of the present application, including:

[0036] S101. Before the BLE chip enters the standby mode, write the value of the register of the specified component into the RAM of the BLE chip.

Abstract

The application discloses a BLE chip, a method for controlling specified components therein, and a Bluetooth low-power consumption device. The method includes: before the BLE chip enters the standby mode, writing the value of the register of the specified element into the RAM of the BLE chip; when the BLE chip enters the standby mode, stopping power supply to the specified component; when the BLE chip switches from the standby mode When entering the active mode, write the value previously written into the RAM into the register, and continue to supply power to the specified element. By pre-saving the value of the register of the specified component before the BLE chip enters the standby mode, and then rewriting the register after activation, the power consumption of the specified component in standby mode can be significantly reduced, thereby saving device power consumption and improving battery life.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a bluetooth low power consumption BLE chip and a control method for specified components therein. The invention also relates to a bluetooth low power consumption device. Background technique [0002] With the continuous development and application of electronic equipment, hardware and software functions have been greatly improved, and the power consumption is also increasing. However, the current ordinary batteries cannot provide power for a long time. Therefore, in order to improve Battery life and performance, the requirements for low power consumption of electronic equipment are also getting higher and higher. [0003] In today's lifestyle, home automation, terminal and medical applications often use short-range communication, and with applications such as wearable electronics often using coin cells, low-power communication is an urgent requirement. Therefore,...
