Hello,
I've been able to somewhat reduce the power consumed by an ATM1281-based
Zigbit device by switching off the radio and the UART port (via
SerialActiveMessageC) during periods of inactivity, but I've been unable
to get below 0.4 mA. I tried to explicitly disable the I2C bus as well

Hi Bharti,
Also, I'd make sure to call I2CPacket.isOwner() inside
I2CPacket.readDone() just to make sure, and populate your local.reading
array if the return value of isOwner yields TRUE.

Hi Sofia,
I suggest assigning a different channel for each network. This way,
motes from one network won't interfere with the motes in the other.

Hi Felipe,
In line 110, you are declaring a typedef "frmCtrl_rx" as a pointer to a
frameCtrl_t structure. But that's the typedef only; you never actually
declared a variable of your typedef. You need to declare a variable of
type frmCtrl_rx and then do the assignment, e.g.:
typedef frameCtrl_t

Hi Eric,
I don't know whether the radio drivers for the respective chips

it means that the packet's transmission is indeed

Hi Sergio,
Sorry, I thought you're using the 868/900 MHz version. My changes are
only for the rf212 (or other slower than 250kbps radios). The rf230
should work, it's well tested on the iris motes.

Hi Napoleon,
When working in the HW mode, the transceiver automatically issues an ACK
upon receiving a data packet from the MAC layer. A local notification is
also sent to the system to let it know that there is a packet ready for
reading, but for some obscure reason the packet is not always de

Hi Sean,
The receiver must know in advance the radio frequency over which radio
transmissions will take place. Otherwise, you can implement a channel
scanning routine at the receiver, or leave the receiver's frequency
fixed, and have the transmitter send 'hello' packets sequentially on
each ch
