İnfinite advertising with proximity application nrf80001 vs nFR51822

[berkan]

I would like to build a avdertising node for the public usage. So without previous bonding everybody should take the advertising through mobile application. Application is similar to "Estimote". I have got two quesitons.

1)Can nRF8001 do that with not needing any extra microcontroller? Or I should use nRF51822?
2)If i got an external processor for nRF8001 which one is better to time to market compared with nRF51822 considering Readyapps for mobile and and the software libraries?

And is it possible to program nRF51822 wirelessly?

Thanks Berkan

The nRF8001 is a connectivity chip that needs an external application controller to do anything useful. If you have this, you could however do infinite advertising, although with some limitations on advertising data sizes and formats.

The nRF51822 on the other hand can do such applications with ease, infinitely advertising and advertising with any data format needed. You can take a look at this question for an example of how to for example advertise as an iBeacon.
