Use a beacon to look for other beacons?

[Greg Winn]

Hello, I would like to build a device that looks for other beacons (not using a phone)... This device would simply look for other beacons near this device.

My questions:

1. I use the NRF51822 in my current beacon design am I able to use the same chip or is there something else?

2. Are there any code examples available??

Any help would be awesome!

1. nRF51822 or nRF51422 can be used. If you don't use ANT, you should use nRF51822.
2. I have made an example with the S130 0.9.0-1 alpha. It is advertising and scanning.

Here is my project. I used SDK 7.1.0 (S130 0.9.0-1 alpha headers), and PCA10001.

Extract it to C:\Keil_v5\ARM\Device\SDK7.1.0\examples\ble_central_and_peripheral\experimental

It has a advertising interval of 500 ms.

It toggles LED 1 every time it receives an advertising packet from device address search[]

By chance do you know if I can accomplish this on mbed? I have the nRF51 (with the nRF51422) Dongle for testing...

I have unzipped it to the folder you show above but i am not able to build it i get 5 errors all for missing files..

D:\Keil_v5\ARM\Device\nRF51_SDK_7.1.0\components\drivers_nrf\hal\nrf51.h(119): error: #5: cannot open source input file "core_cm0.h": No such file or directory

On mbed? In the mbed compiler? On a mkit? I think you should add a new question and link to this one if it is relevant. Please include what hardware you are using and what you are trying to do.
