CC2541: MPN #CC2541F256RHAR 48bit IEEE address duplicates

Part Number: CC2541


we only uses the last 24-bit IEEE address and, encountered an issue with duplicated IEEE address,  any solution to differentiate ?  


  • There are two units using "EF0196" QR code for device scanning but the full device ID is different. Refer the below ID read out from CC debug programmer.

    One unit device ID is DCF31CEF0196, another unit device ID is 38AB41EF0196, both units' device ID end with EF0196.

  • Hello ZhenZhi,

    Thanks for reaching out. What SDK version are you using?

    Can kindly ask for you to show me how / from where are you reading the device ID?
