CONFIDENTIAL 1. UART COMMUNICATION PROTOCOL: The following section describes the communication protocol between the HRM3300 and Equipment console. The protocol is intended to provide a reliably link between the HRM3300 and Equipment console. The UART protocol supports the two way link communication between the two devices. 1.2.Block Diagram 2. OPERATION 2.1. Description The Equipment console and HRM3300 uses standard UART protocol to transmit and receive custom packets.
CONFIDENTIAL 2.2. UART Specification Baudrate: 9600 (default), 4800, 2400, 115200 Parity: No parity Flow Control: Disable 2.3. Equipment Assumption Upon power up of the equipment device, the HRM3300 is also power up. Since the equipment is controlling the HRM3300, the HRM3300 will be on the idle state or waiting state for the command from the equipment console. 2.4.

CONFIDENTIAL 2.6. HRM3300 OTA. The new code update can be flashed into the device using over the air programming. The BLE DFU feature of OEM3300 can be triggered using the activation command from the console. Once triggered the OEM3300 function as BLE peripheral and will broadcast “OEM_3300”. Using Nordic NRF Connect application installed in the phone and the OAD zip file released, the OEM3300 firmware can be updated.
CONFIDENTIAL 3. UART COMMUNICATION PROTOCOL PACKETS 3.1. Packets The uart protocol packets contain data that will be used as an interface between the HRM3300 and the equipment console. A maximum of twenty four bytes and a minimum of eight bytes are used during Uart communication. Fletcher checksum reference: https://en.wikipedia.org/wiki/Fletcher%27s_checksum For 5kHz analog strap, the name to be transmitted will be “5kHz HRM”.

CONFIDENTIAL Appendix A : HRM3300 Placement Guideline The electrical noise generates from the machine could affect the reception range of 5KHZ wireless receiver. It is better to avoid any noise frequency near 5KHZ or harmonics get near the module. Although not all electrical noise can be avoided, the following sources could contribute to the interference. It is recommended to position the HR wireless module as far from these sources as possible.
CONFIDENTIAL The ideal placement location of the HR wireless module would be at the center, toward the front that is closer to the user, and away from the noise sources. In case the wireless module has to place off to the left or right side from the center of the console, then try to keep the offset distance within 12 inches (30cm) or less, otherwiseThe reception distance of the HRM will be shorten if it is placed too far off from the center.
