I was not able to find any examples/libraries for nRF51 that does what you are asking about (However if you switch to nRF52 and SKD 15.2, it can be achieved easily: link), but it is possible to write the code yourself.

• I would start by making a structure type device, which represents a device and its fields (e.g. a field for the name and the UUID).
• Then I would add some code in the function that receives and handles ble events (for example the function on_ble_evt(..) in the ble_app_uart central example in sdk 12.3)
• The BLE event has a field that contains the advertising data (name, UUIDs and flags), and this link explains how to decode the advertisement data in the payload
• Then you declare a new variable (using the device type) and put it into an array/list, every time a new name appears
• Now you have a list of the devices present, and can display it however you want to

Here is a link that may help you.

Best regards, Simon
