Primary Receiver (PRX) connector
This module provides a :whad.esb.connector.prx.PRX connector that
implements Nordic Semiconductor’s Primary Receiver role.
The primary receiver (PRX) role consists in receiving packets from other devices and sending acknowledgements if required to the sending device. When a device is in PRX mode, it is only capable of receiving ESB packets on a specific channel, including ESB pings.
The whad.esb.connector.prx.PRX class relies on a custom protocol stack
to handle acknowledgements and pings automatically.
