How to get 6 byte mac address at nrf51822

[Lee YongKwan]

When I scan BLE device at nRF UARTv2.0 App in Android4.4, it is appar device name(Ex:Nordic_UART) and 6 byte device address(MAC address?). I want to include mac address in device name. How to get 6 byte mac address at nrf51822?

Here IEEE SA RA provides a guide on MAC organization and assignment for production devices:

Hello ,

I want to display the 6 byte mac address of mycustom card by uart (I already configured uart), i want to know how I can use the registers NRF_FICR-> DEVICEADDR [0] and NRF_FICR-> DEVICEADDR [1] to achieve my objective.(if there are any example of that )

thanks

What is the smallest part of MAC address that can be used as a unique ID of a certain device?

I know that first 3 bytes are vendor-specific (Nordic) so another 3 bytes are unique across Nordic products. But are they totally random, or is there any pattern that can allow us to use only 2 bytes for a specific product (nRF51822)?

So to confirm - the addresses are randomly selected but unique to any given nordic nRF chip? So your production will check for uniqueness and assign a new random number should a new selected address already exist. The reason I am confirming is that we need to rely on a unique identifier for our own production. Thanks
