Detailed Description

This example connects to the nearest Heart Rate Monitor (HRM) in range and prints the UART data when it is received from the device.

HRM specific configuration options

The following compile time configuration options are available to suit various HRM receiver implementations:

• HRMRX_NETWORK_KEY ANT PLUS network key.
• ANTPLUS_NETWORK_NUMBER Channel network key.
• HRMRX_ANT_CHANNEL Channel number.
• HRMRX_DEVICE_NUMBER Device number.
• HRMRX_DEVICE_TYPE Device type.
• HRMRX_TRANS_TYPE Transmission type.
• ANTPLUS_RF_FREQ Channel radio frequency - offset from 2400 MHz.
• HRMRX_MSG_PERIOD Channel period - in 32 kHz counts.

Development phase configuration options

Depending on the selected compile time configuration, the HRM receiver will trace the profile specific state information to the UART.

The following options for the compile time configuration are available in the development phase of the HRM receiver implementation:

• TRACE_HRM_PAGE_NMBR - output page number of the current page to UART.
• TRACE_HRM_PAGE_1 - output page 1 data to UART.
• TRACE_HRM_PAGE_2 - output page 2 data to UART.
• TRACE_HRM_PAGE_3 - output page 3 data to UART.
• TRACE_HRM_PAGE_4 - output page 4 data to UART.
• TRACE_UART - UART output enabled.

Note

The ANT+ Network Key is available for ANT+ Adopters. Please refer to http://thisisant.com to become an ANT+ Adopter and access the key.
