@chris There’s a few ways to do that. One easy way could be to configure your mote firmware to contain a dwell period in the main loop either before or after your data parsing code. I am stronger in C so I’ve made ample use of delay() but I bet you C++ has something like a sleep() or something. The example code in Guide 5, here, has the general structure of the loop can be seen.
Another way which could be less computational overhead (since you might want to do other things during the dwell periods) may be to tie the data collection to the GPS time…I don’t know if that’s in the docs yet but maybe I can tag in @evan on the new post (Setting Duty Cycle) to help us understand if there’s an easy way to do that or if we missed it somewhere already in the guides.
