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

Thanks. That's really helpful. Can you also let us know when i check on the Master Control Panel it displays the Device Name also with the Device ID from the FICR register. From where does it reads this Device ID. Is it transmitted in the advertising packet? Or is there an service or anything to implement it.
