ANT + Sports Health Application Solution

ANT + protocol is widely used in sports, health and medical fields due to its low power consumption and convenient network construction. The ANT + sports health module is developed for the convenience of users to build the ANT + sports health system.

This module is embedded with ANT + protocol, which can be easily embedded in sports and health equipment to support ANT + function. This module can communicate with standard ANT + equipment to facilitate users to establish a wireless sports health monitoring system.

Users can send motion data to this module through the serial port. This module automatically transmits the data through the ANT + protocol. At the same time, the module can receive the ANT + signal and transmit it to the device through the serial port. Therefore, the module can be applied to the host or slave side of the ANT + device.

This wireless module takes the single chip microcomputer NRF51422 as the core. NRF51422 is a SOC chip with low power consumption, built-in 2.4G wireless transceiver and 32-bit Cortex-M0 core. The 2.4G wireless transceiver is responsible for sending and receiving wireless signals at the physical layer, and the M0 core is responsible for the packaging and parsing of the ANT + protocol at the protocol layer.

This module has the characteristics of low power consumption, small size, simple structure and convenient use.

ANT + sports health module software consists of 3 modules, namely ANT + module, serial port module and IO input module.

After the module is initialized, the serial port and wireless start to monitor the data. When it detects that the serial port has data input, the serial port input data is sent according to the ANT + protocol; when a wireless signal is received, valid data is parsed from the ANT + protocol and output through the serial port.

The ANT + protocol has the advantages of flexibility and low power consumption in many wireless applications. Engineers can more easily build highly flexible, low-power wireless solutions to achieve low data rate applications such as wireless sensors.
