Comments
Before setting this register, the ACTIVATE instruction followed by the byte 0x73 must be sent to the radio to activate the special features.
See the DYNPD Register for more information on dynamic payloads.
This project doesn’t implement dynamic payload length or ack payload.
Dynamic ack is used in this project to disable acknowledgements to broadcast packets.
