Hi, What is the difference between a software acknowledgement and a hardware acknowledgement on CC2420 radio chip ?
I checked CC2420Config.isAutoAckEnabled() and CC2420Config.isHWAutoAckDefault() and the results are respectively 1 and 0. So I think that I use a software acknowledgement. In my mind, software acknowledgement check the request flag and CRC. If both are good, CC2420ReceiveP send the Ack (SACK.strobe) So, what is a hardware ack ? Does it check the request flag and CRC before sending an ack or just the CRC ? Is it more reliable than a SW ack? Does it require to use PacketAcknowledgements.requestAck() ? Thanks. Fred
