External 32 KHz crystal oscillator


Is the external 32 KHz crystal oscillator optional or is it a must for a DA14580 design to be used as a BLE peripheral device?

Thanks in advance,

Hello Mamigot, sorry for

Hello Mamigot, sorry for delay. What we find is that for connection interval <2seconds, then the intenral RCX is normally suitable. For connection interval >2seconds, then XTAL is needed (otherwise connection will be lost due to accuracy of the RCX). We'll be publishing some infomration on tihs in due course.
