Cypress Perform

Answer: AgileHID™ is Cypress’s proprietary wireless software protocol optimized for wireless HID devices. It provides a set of APIs to develop wireless mouse, keyboard, and bridge applications thereby allowing WirelessUSB-NL customers to get started quickly on their designs without any additional effort. This protocol runs on Cypress’s radio driver and enCoRe™ MCUs. As the dongle is connected to the PC through USB, this protocol also uses USB driver APIs to transfer packets to and from the PC.

The protocol provides the following functionalities:

1. Binding device (mouse/keyboard) with bridge connected to PC
2. Packet transmit
3. Packet receive

The following functionalities of the protocol are not visible to application:

1. Configuring transmit, receive, and transaction parameters
2. Channel change algorithm to handle interference/noise
3. Reconnection between device and bridge
4. CRC generation
5. Network ID generation
