If you don't really care what protocol you are using you could also have a look at the 'Enhanced Shockburst'-examples in the SDK.

This will be a simpler solution when doing a 'Nordic to Nordic' link, rather than using the BLE protocol.

Thank you very much Stefan!

I updated the answer to answer your question. If you use the ble_app_multilink_central example then you must use the ble_app_multilink_peripheral example on for the peripheral device. If you use the ble_app_hrs example on the peripheral device then you can use the ble_app_hrs_c on the central device

Hi Stefan,

If I use the ble_app_hrs example on the Evaluation Kit board PCA10001 and use the ble_app_multilink example on PCA10000, will the central connect to the peripheral automatically? When using the Master Emulator, I have to press Select Device, Discover Services and Enable Services. Will this happen automatically if I use the ble_app_multilink example? Thanks for the help

A good way of getting started with BLE develepment on nRF51822 is to read this blog post

If you want to communicate with BLE between two nRF51822 device, the ble_app_multilink example is set up to do that. However, that board is set up for the nRF51822 development kit together with the nRFGo Starter kit. You could also flash ble_app_hrs (peripheral device with S110 stack) code to one device and then flash ble_app_hrs_c (central device with S120 stack).

Update 13.11.2014 If you flash ble_app_hrs to the evaluation board (first flash the S110 softdevice) and then ble_app_hrs_c to the PCA10000 dongle (first flash the S120 softdevice), then it should work. Just remember to comment out the code that calls the display, as described in the documentation for the ble_app_hrs_c example.

The ble_app_hrs_c scans for ble devices and advertising reports are received in on_ble_evt->BLE_GAP_EVT_ADV_REPORT. If the heart rate UUID is found (0x180D) a connection is establised with the peripheral. When connection is established, service discovery is performed, and services are enabled automatically.

Perhaps you may consider to use the nRF51-BLE-driver in order to control the nRF51 device from a PC application.

I too am trying to do exactly this. I am trying to figure out the ble_app_multilink example (that is given in the nrf6310 SDK) however I can't seem to figure it out. I'm a bit of novice with microcontroller programming so an example of showing a link between a nrf58122 acting as a central and a nrf518222 acting as a peripheral would be great
