nRF51822 - ID

[Jose Xavier]

Hello,

There is any unique ID per chip that we can use? On my application I'm able to add and remove devices from network, each network consist on 5 to 10 devices. I'm planing to product 100 units, will I need to program a different id code to identify each chip?

thank you

The Chip ID is not guarenteed to be unique. These numbers are set in production and should be random numbers (FIPS compliant).

This are 64bit DeviceID, the odds of collision are fairly small, but non zero. If this is something very important for your design, you can manage this easily in your production by using nrfjprog command line tool.
