Re: [Contiki-developers] Tmote sky low-power modes

[Jonathan L. <jo...@cs...>]

Hi Bjorn,

Thanks for the tip about putting the M25P80 chip into "Deep Power-down (DP)"
mode. I'll investigate. However, if anyone knows off the top of their head
how to do this I would much appreciate them posting it here.

Cheers

	Jon
