This application demonstrates the capabilities of the experimental ANT Auto Shared Channel example from Nordic Semiconductors nRF51 SDK 7.2+.
The sample supports up to two ANT+BLE hubs and up to 15 ANT-only nodes for each hub. At least four boards are required to utilize all features of the reference design.
