1. Is there a development board for CC2571?
2. Will CC2571 communicate with CPU, when using UART communication only need to reserve RXD/TXD/RST/VCC/GND five pins?
3. Ant + function of CC2571 is adopted. Does the chip come with Ant + protocol?Can be directly used after hardware connection?
4. Can I communicate directly with other Ant + modules when using it?
