GEM3NFC Hardware Manual Overview and Key Features The GEM3NFC module is been designed to allow OEMs to easily add Bluetooth, ANT+, Apple GymKit, Samsung Galaxy Active/Active 2 and NFC reader connectivity in their product offering.
Specifica8on Specifica8on Summary Category Feature Implementation RF Bluetooth 4.2 Single Mode Peripheral ANT+ Broadcast Frequency 2.402-2.480 GHz Maximum Transmit Power +8dBm Minimum Transmit Power -20dBm Receive Sensitivity -95dBm Range up to 360m line of sight Reader Tag Type 1,2,3,4,5 Frequency 13.
GEM3NFC Overview Overview The following picture provides an overview of the various hardware elements of GEM3NFC board. NFC Antenna Additional I/O GEM3 NFC Reader Data, Power & I/O Data, power, & I/O connector The data, power, and I/O connector provides a means to connect a supply voltage of 3.3V to the GEM3NFC module as well as UART TX and RX lines for serial communications between the GEM3NFC module and the Jitness equipment console MCU. The GEM3NFC UART lines are TTL level and operate at 115.2Kbps.
Addi8onal I/O The GEM3NFC module includes an additional connector for I/O. NFC Reader The GEM3NFC module incorporates an NFC reader chip allowing for decoding of compatible NFC tag data records enabling tap to pair support as well as NFC based user identiJication. NFC Antenna The GEM3NFC module includes an integrated NFC antenna. GEM3 module The GEM3NFC includes North Pole Engineering’s GEM3 Bluetooth 5.
Opera8ng Modes GymKit The GEM3NFC module when integrated into a Jitness equipment device can pair with a compatible Apple Watch using a “tap to pair” method where by an Apple watch is brought near an area of the Jitness equipment console where the GEM3NFC’s antenna has been located. The GEM3NFC module will sense the presence of the Apple Watch through it’s NFC antenna and reader circuitry and perform the necessary procedures to establish a Bluetooth connection with the Apple Watch.
User messaging User conJirms connection and GEM3NFC establishes a Bluetooth connection with the Watch, performs link bonding, encryption, and authentication functions with the Watch User begins workout. GEM3NFC relays data from Jitness equipment to Watch using Bluetooth Jitness machine service. GEM3NFC receives HR and Calorie data from Watch using GymKIt service.
User messaging GEM3NFC is idle awaiting connection from Watch or app through a Bluetooth connection. User initiates Bluetooth pairing through the console user interface and conJirms connection with the smart device. User begins workout. GEM3NFC relays workout data from Jitness equipment to smart device app using Bluetooth Jitness machine service. GEM3NFC sends received HR data to Jitness equipment console for display.

GEM3NFC Considera8ons Mechanical items (especially metal) should be kept as far as possible from the module antenna in all directions, including above and below the board surface. If possible, move mechanical items out and away from a keepout area of 53mm x 20mm from the GEM3NFC module edge. Antenna Characteris8cs The GEM3NFC module includes an integrated monopole chip antenna. Antenna performance will depend on host PCB layout. The following plots show antenna radiation pattern of the GEM3NFC antenna. 2.
Mechanical Informa8on Dimensions (in mm) 5.00mm 5.00mm 40.00mm Ø3.18mm Connec8ng GEM3NFC to Console MCU The GEM3NFC is designed for connection to Jitness equipment console MCUs through its Serial interface. The GEM3NFC serial interface has a TX line and RX line that are 3.3V tolerant and operate at 115.2Kpbs.

GEM3NFC Host Protocol The GEM3NFC supports North Pole Engineering’s GEMHCI protocol for communication between the GEM3NFC board and the console MCU using the GEM3NFC module’s serial host connection. The GEMHCI protocol supports a port speed of 115.2Kbps. The GEMHCI protocol is a binary protocol and is used to conJigure the GEM3NFC operation as well as pass Jitness equipment related data to the GEM3NFC for broadcasting to connection applications using its Bluetooth/ANT+ radio.
ISO/IEC 14443B card mode Regulatory & Standards Informa8on FCC & Industry Canada The GEM3NFC module has modular approval for the United States and Canada. To ensure compliance when using the GEM3NFC module in a design, the OEM is required to adhere to the implementation considerations supplied in this hardware integration guide. Federal Communica8on Commission (FCC) Radia8on Exposure Statement: This device is in compliance with SAR for general population/uncontrolled exposure limits in ANSI/IEEE C95.
FCC Labeling Requirements WARNING: The OEM must ensure that FCC labeling requirements are met. This includes a clearly visible label on the outside of the OEM enclosure specifying the appropriate FCC identiJier is visible. Contains FCC ID: XRH-NPE109 IC: 11922A-NPE109 If OEM device is larger than 8x10cm, the following FCC part 15.19 statement has to be visible on outside of device: The enclosed device complies with Part 15 of the FCC Rules.
DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION. Industry Canada (IC) Warning: This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.
NOTE IMPORTANTE: Dans le cas où ces conditions ne peuvent être satisfaites (par exemple pour certaines conJigurations d'ordinateur portable ou de certaines co-localisation avec un autre émetteur), l'autorisation du Canada n'est plus considéré comme valide et l'ID IC ne peut pas être utilisé sur le produit Jinal. Dans ces circonstances, l'intégrateur OEM sera chargé de réévaluer le produit Jinal (y compris l'émetteur) et l'obtention d'une autorisation distincte au Canada.
CE The GEM3NFC Module has been tested against the appropriate regulatory standards for European market. OEMs should consult a qualiJied test house to ensure their product meets all regulatory requirements. The GEM3NFC Module Declaration of Conformities is below. Test reports are available upon request. Health and Safety – EN60950-1: 2006+A11:2009+A1:2010+A12:2011 Electromagnetic compatibility – EN301489-17 V2.2.1 in accordance with EN 301 489-1 V1.9.2 Radio Frequency Radiated Emissions: EN300 328 V1.9.
Bluetooth Qualifica8on The Bluetooth SIG requires every product implementing Bluetooth technology to have a Declaration ID even though the end product references a Bluetooth design with its own Declaration ID. An over of the Bluetooth SIG QualiJication Process is as follows: 1. Register as a member of the Bluetooth SIG – www.bluetooth.org 2. Go to product listing page https://www.bluetooth.org/en-us/test-qualiJication/ qualiJication-overview 3. Go to Create a Listing: https://www.bluetooth.org/tpg/QLI_SDoc.
