Im currently developing a low power IoT node based on Contiki-ng running on a TI CC1350 launchpad board. My problem is that my power consumption is always >6mA.
Compiling and running the energest
example I can see the MCU radio is always listening, no matter if I compile with MAKE_MAC = MAKE_MAC_NULLMAC
and MAKE_NET = MAKE_NET_NULLNET
. Running
MAKE_MAC = MAKE_MAC_TSCH
or MAKE_MAC = MAKE_MAC_CSMA
increases consumption by around 2mA as the CPU is always active, but the radio is never duty cycled.
Is there a way of reducing current consumption for Contiki-ng on this platform?
With Contiki-NG, you have two options:
NETSTACK_RADIO.off()
.If you the latter, still see big consumption, and you're sure about your code, submit an issue to the Contiki-NG git - there can be an energy consumption bug in the OS specific to the CC1350 board.
