How do i distinguish between many ble devices advertising same name?

[SumitS]

Hi,

I am developing a glucose application using nrf51822 chip. Now i want to go for mass manufacturing. All my devices are advertising the same name. I want to identify a particular device while scanning. How can i distinguish between multiple devices advertising the same name? Does each Nordic chip has some unique identification number?

Thanks & Regards, Sumit

Hi,

All devices will have a random generated BLE address, even if they have the same advertising name. This address is derived from the FICR register, and is set during our production. You can read more about this here: devzone.nordicsemi.com/.../

Cheers, Håkon

Can i read this address using a custom code that will be developed on iOS. Currently i am only able to read the services and manufacturer data and device name. Can you guide us as to how to read the this address in our iOS code.
