How to turn on/off mesh

[sphudson]

I am using the RBC mesh in a networking product using the nRF51422. We would like to turn the mesh on and off at selected times, say once per hour for a minute or two. I know how to turn on (init) the mesh. But, what is the best way to turn it off such that the radio is at minimal power?

Thanks in advance --s

The framework now supports start/stop actions for the radio activity, see release v0.6.9. Note that this only stops radio activity, while the memory remains allocated and local functionality is kept.

It works by aborting the running timeslot, and stops all ordering of new ones from the Softdevice.

That seems reasonable. If you don't want to push data to the sensor, you can actually do this only by advertising, if you follow the packet format. Enabling the mesh will force you to do some scanning, and it might take up to 100ms to get a response from the master, but it's not an unreasonable approach. The end node does not need to reestablish its network role, or negotiate some slot from the master in any way. It can wake up, send, and go back to sleep, without any management overhead.
