I am trying to develop a low power scanner with nrf52832 which is is acting as both central and peripheral (beacon)
I need to detect other tags like itself transmitting nearby (max 2m). Their advertisement interval can be adjusted
I need to identify the tag only if it is more than 2min in the range of the receiver
I thought about the following ways:
1) Scan only 2 times per 2 minutes. For example Scan for 200 msec then sleep for 1 min and then scan again
The peripheral will advertise at 100msec rate.
2) Scan only 1 channel e.g. 37, the advertising will be on channel 37 as well
3) Use tilt switch for that will disable and scanning and the advertising if the tag doesn't move
Are there more ways to enable low power device (scanner + beacon)?
It is hard to estimate the power consumption...
What is the power consumption of the receiver doing partial scanning with window of 200msec every 2 min?
