ANT+ and Bluetooth LE in one chip
Nordic Semiconductor has announced a chip with concurrent ANT+ and Bluetooth low energy wireless communication.
“ANT paved the way for interoperability in ultra-low-power wireless and continues to set the bar in terms of overall performance and power consumption.” said Nordic marketing manager John Leonard. “The sports and fitness market is dominated by ANT+ enabled products from wireless heart-rate strap to bike power meters. And new market segments continue to open up. In parallel, Bluetooth Low Energy has attracted interest since its arrival in 2011. With the adoption of Bluetooth v4.0 [which includes Low Energy] in just about every new smartphone, its connectivity appeal is obvious, creating unlimited sensor and control possibilities.”
Called nRF51922, the chip is drop-in compatible with the firm’s existing nRF51 series devices. ANT+ and Bluetooth Low Energy stacks are in a single software framework called S310.
“S310 includes a clean separation of protocol stacks and application firmware to simplify firmware development and testing,” said Nordic. S310 shares an interface with its S110 (Bluetooth Low Energy) and S210 (ANT+) stacks.
Customers with an existing nRF51 ANT+ or Bluetooth Low Energy product will “be able to keep existing hardware design and firmware unchanged, and only add needed firmware support for the new protocol stack,” said Nordic.
