[Tinyos-devel] status of the default-lpl

[Miklos Maroti]

Hi Razvan,

I completely do not understand your naming of the commands. I think we
should have

void setTxSleepInterval(message_t *msg, uint16_t sleepIntervalMs);

because that is the value we use to transmit the message (the length
of the preamble / wakeup signal). Then we have the other command which
controls how we sleep while receiving messages. I think that should be
called:

void setRxSleepInterval(uint16_t sleepIntervalMs);

I like this much better than the "LocalSleepInterval". Maybe I am just
wired in differently.
