Hi,
are you sure the FCF of your packets that need to be ACKed have the
Request-ACK-Bit set?
Only then ACKs are automatically send by the hardware.
I've never worked on this with micaz, but on telosB this worked fine for me.
Although I think the ACKs send by hardware were not compatible with the
TOS_Msg struct.
Not sure about that though either :-)
But if you can see that NO packets are sent and are sure of that: check
the FCF.
good luck

Hi,
we are exploring micaz communication features.
We have read on chipcon cc2420 datasheet that this transceiver
implements an own acknowledgement procedure, setting register
MDMCTRL0_autoack:
we set this register using command:
CC2420Control.enableAutoAck();
after enabling Addres decode using command:
CC2420Control.enableAddrDecode();
we expect an automatic ack message sending, but it doesn't transmit
anything.
Does anyone have an idea?
Thanks in advance,
Davide Di Palma
