### power-cycle sensortag
<nothing>
So it seems like hcitool must first tell bluez to listen for
advertisement packets. Is there documentation/samples on how to do this
with python or C? Any other programs that do this, so I can read their
source?
Also, only the first advertisement of the SensorTag is shown. While that
probably makes sense for traditional advertisements, my use case
requires that all advertisements are shown, as I'm trying to transmit
low-rate data from the tag's sensors in the advertisements.
Do you have some hints concerning the easiest way to receive and process
those advertisements, preferably without the hassle of user-interaction
and multiple terminals?
Cheers,
ben
