iBeacon kit can work at internal 32.768KHz RC?

[Jeffery]

Hi sir On your Beacon kit, we found it was used external 32.768KHz at 20ppm.

Question is on iBeacon usage, is a external higher precision 32.768K crystal necessary ?

Or customers can use the built-in RC one ? Thanks

Hi,

You can use the built in RC. The external crystal is there in case we would like to use the kit for something else as well ;)

Best regards,
