Anglo-American health gear producer, WaterRower, is using Nordic Semiconductor Bluetooth LE wi-fi connectivity in its rowing machine efficiency displays to offer customers with ‘actual time’ entry to motivational packages and data-driven incentives to coach smarter and maintain match.
The WaterRower rowing machines are manufactured from a choice of sustainable hardwoods, and, in contrast to conventional fan or magnetic resistance machines, harness the ability of water to offer clean and even resistance and a sensible rowing expertise in each sound and really feel. The corporate’s ‘S4 Efficiency Monitor’ might be mounted to the rowing machines and shows a spread of time, distance and depth metrics.
Plug and play efficiency
The brand new S4 Efficiency Monitor integrates Perception SiP’s ‘ISP1907-LL’ multiprotocol module primarily based on Nordic Semiconductor’s nRF52811 SoC. Earlier technology S4 Efficiency Displays might be retrofitted with the ‘WaterRower ComModule’ that merely plugs into the again of the monitor and in addition integrates Perception SiP’s ISP1907-LL module. The inclusion of the Nordic-powered module in each the brand new S4 Efficiency Monitor and WaterRower ComModule gives Bluetooth LE wi-fi connectivity to the ‘WaterRower Join’ iOS and Android app. From the app the person can assessment their metrics and exercise historical past in addition to be guided by means of extra superior exercises through an optionally available subscription service.
“WaterRower is designed to copy the expertise of rowing in a ship, and is as near being out on the water as you may get within the consolation of your individual house,” says Chris Footner, challenge design supervisor, WaterRower. “Whereas the design has saved its core options for a few years, connectivity has develop into a vital a part of fashionable health gear which made the Perception SiP module primarily based on the Nordic SoC a great answer for the subsequent technology of our merchandise.”
Perception SiP’s ISP1907-LL is an ultra-miniaturised module primarily based on Nordic Semiconductor’s nRF52811 multiprotocol SoC. The totally built-in module is obtainable in an 8 by 8 by 1 mm bundle measurement with a built-in antenna and is designed for space-constrained purposes. The nRF52811 SoC combines a strong 64 MHz, 32-bit Arm Cortex M4 processor, with a 2.4 GHz multiprotocol radio that includes 4dBm output energy with -97dBm sensitivity (at 1Mbps in Bluetooth 5 mode), and 192 kB Flash reminiscence plus 24 kB RAM.
The S4 Efficiency Monitor is powered by replaceable AA batteries, offering an lively person greater than 200 hours or over a yr of use between substitute, thanks partly to the extremely low energy traits of the nRF52811 SoC within the ISP1907-LL module. Exceptionally low vitality consumption is achieved utilizing Nordic’s subtle on-chip adaptive energy administration system.
Improvement instruments made easy
“A number of of the instruments made out there by Nordic have been crucial in reaching design targets, for instance the addition of OTA [over-the-air] updates to take care of our units sooner or later,” says Footner. “Along with a full function IDE [Integrated Development Environment], this made growth a extra nice expertise.
“Of all of the options we’ve got tried prior to now, Nordic out-does everybody with its in-depth datasheets, SDKs and reference designs. Inside minutes we had demo firmware loaded into our prototype {hardware} prepared to check.”
