Preliminary

7.2.9

Broadcast Attempts

EEPROM Address: 4EH
Size: 1 bytes
Default: 04H
Range: 01-FF

The Broadcast Attempt parameter applies only to the Broadcast modes for all four serial packet

modes and specifies the number of times that the RF will broadcast every packet. The receiving radio will
discard duplicate packets.
