Hi,

Could you be more specific on your application ? Which device will be involved in your indoor localization system ? I assume here you will have nRF51822 on both side the transmitter and the receiver and there is no phone involved. Then the next question comes, why do you need BLE for the application ?

If you plan to support phone/tablet in the future and that is the reason to chose BLE. It's feasible, as you can use the S120 central BLE stack on the nRF51 as the central device which receive and calculate the RSSI value when receiving advertising packet from peripheral notes.

You should be able to get the RSSI of each channel in the 2.4GHz band by sweeping through it. There is an example get the RSSI from the radio in the timeslot API example. You can use this to make your program that will sweep through all the channels and get the RSSI value when the receiver is turned on in that channel.
