Developing Beacon and Scanner using nrf52 dongle & nrf52840 DK respectively

[kaushik24psl]

HI as i am new to nrf nordic semiconductor development i have some quetsions regarding application im developing

I am trying to develop Ble application where nRF 52 will be the beacon and nRF 52840 DK will be the scanner module.

1.I have used nRF_SDK_15.3.0_59ac345/examples/ble_pheripheral/ble_app_beacon/pca10056/s140 program form nRF 52 dongle to operate it as a beacon when code is uploaded device gets detected on mobile nrf beacon app..and also by using printf i can varify the data which is being transmitted by beacon..

2.Second thing is i have nRF 52840 DK which i want to use it as a scanner for beacons (nRF52 dongles) .when beacons come in range of scanner it should detect the beacons and advertise      the report accordinly in debug terminal.

   For scanner application i have tried using 3 codes

1.ble_app_multipheripheral_pca10056

2.ble_app_multilinkclient_pca10056

3.ble_app_uart_c_pca10056

I am not sure about which one will work properly.as far as i tried and tested multipheripheral worked ok with nrf blinky clients.

so i want help from your side in making nRf52840 as scanner using some modifications in this codes..and so that it can scan any no of beacons of nRF52 dongles.

A beacon cannot tell when it is in range of a scanner!

The name comes from the normal English word "beacon";  it is some thing which just shines - like a lighthouse.

Yea ur correct when beacon comes in range of scanner it should get detected .thats why i want to make the scanner using above code to detect those beacons .

we dont want beacons to tell when it is in range of scanner ..

as beacon gets connected to scanner ,scanner should either advertise the data receveid from beacon that is rssi value and UUID.and make the on mode LEDs active whan beacon is in range ..thats it..

So you need this device to be both a Scanner (Central) listening for & connecting to beacons and an Advertiser (Peripheral) re-broadcasting the data that it has collected?

That sounds remarkably similar to this:

That is actually a lot!

Especially considering:

Do you have experience with any other microcontroller(s) ?

I have tried Your above link and tried to build the it gives error nrfx_power_clock.c no such file or directory..

i have also tried to download nrfx_power_clock.c  directory from GitHub and include in drivers folder as specified by path .But still error is same ...plz provide the correct sample code

Hi,

You will get an error if you are referencing nrfx_power_clock.c in SDK 15.3, since it no longer exists. It sounds like you are using an example made for an earlier SDK. In SDK 15.3 this file was split in two, so now you need to build nrfx_power.c and nrfx_clock.c instead.
