nRF8002 as a beacon?

[baskan1]

Hi there, I am struggling for 4-5 days but could find a solution yet.

Can nRF8002 be used as a beacon? I read nrf8002 datasheet and also google it alot but could not see an exact answer for it.

Is it true that when nRF8002 sleeps, there is no way to awake it but pressing a button?

So when I find answer above questions, I will decide if I am able to use nRF8002 as a tracking system or not. In a building, forexample there are 200 nRF8002 mobile tags and 10 master(central) device? Do you suggest nRF8002 for this purpose, since it looks like a fast development cycle and a fast learning curve. Or if i go with nRF51822, what development tools do i need at minimum on windows , for just making advertising battery level.

Thank you very much.

The nRF8002 has a limited set of profiles and services that it supports. Beacon is not one of them. So I would recommend to have a look at the nRF51822 instead to use in beacon applications.

For the nRF8002 there are two different low power modes, sleep requires a button push. Idle will wake up on timer.

For development on the nRF51822 I would recommend to start by having a look at the information available in the blog post here: devzone.nordicsemi.com/.../

Thank you very much Asbjørn, I believe, you saved lots of time of beginners, by clarifing that nRF8002 can not be used as a (non-connected advertising only) beacon. And also thank you for the link..

So I decide to go with nRF8122 for "battery level advertising only" application.

As I wrote in my question above, I would like to advertise just battery level. Is it possible to read battery level with "nRF51x22 Reference schematics and layout" in nRF51822-PS document (page 79)?

Since , it seems that there is no mention for in-circuit battery level monitoring in nRF51822.. (This is another question, I coulndnt find an answer in documents)

Thank you for your help so far.

Yes, there's and ADC available on the nRF51822 that will enable you to read the battery voltage and use this as payload in your advertisements.
