Sleep mode for zolertia (z1) cooja #1113

Hello, i just converted my contiki v3 to contiki-ng and I am simulating z1 motes with csma driver in MAC layer. I see that radio is 100% ON during simulation. I know that some layers are merged like nullrdc+csma. However, I want to use a normal scenario where motes have radio off for most of the time and wake up when they receive a packet.In old contiki, I used contiki_mac driver to turn off radio for most of the time. Is that possible with contiki-ng? Or having radio on 100% is normal for a mote like z1? My goal is to measure the energy (and how much time they are ON) of nodes when they send too many packets. Thank you!

The CSMA MAC in Contiki-NG does not do duty cycling. Use TSCH if you want radio duty cycling. Or, if you want to keep CSMA, turn off the MAC layer from the application yourself with NETSTACK_MAC.off().

im a beginner. when i try to add NETSTACK_MAC.off() at the bottom of a 'while' loop and add NETSTACK_MAC.on() after PROCESS_WAIT_UNTIL_EVENT() in the loop, i find that there are no transmit in a udp conmmunication. how do I get the communication back to normal? thank you
