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. The GEM3NFC module incorporates North Pole Engineering GEMHCI protocol software speciJically designed to enable Jitness machines such as treadmills, exercise bikes, ellipticals, stair climbers and step machines to wirelessly communicate exercise data with the Apple Watch, smart phones, tablets, Jitness watches, and leaderboard software systems. The GEM3NFC module is based on Nordic Semicondutor’s nRF52840 multi-protocol Bluetooth and ANT+ chipset and integrates NXP’s PN7150X NFC reader controller. There is also space on the board for the Apple authentication 3.0 coprocessor to be mounted for applications where Apple GymKit support is needed. The GEM3NFC module offers a serial host interface and has a maximum transmit power of +8dBm, and a sensitivity of -95dBm. This manual is intended to assist with hardware integration of the GEM3NFC module into a given design. Details on North Pole Engineering’s GEMHCI protocol software can be found at http://npe-inc.zendesk.com.

Page 8: Operating Modes
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. Once the connection has been established between the Apple Watch and GEM3NFC module, the console and Apple Watch can exchange workout data using the Bluetooth Fitness Machine Service and GymKit service. The following diagram outlines the operating Jlow for using the GEM3NFC for GymKit Applications: User messaging User messaging Integrated Integrated NFC Antenna NFC Antenna Fitness equipment is idle awai0ng connec0on User taps Apple Watch Area on Jitness equipment where GEM3NFC antenna is located.
