CC2640R2F: Sleep mode current issue in 32KHz crystal less mode

Part Number: CC2640R2F

Hi,

I was confirming sleep mode current with CC2640R2F and i have taken reference of 

http://e2e.ti.com/support/wireless-connectivity/bluetooth/f/538/t/734167?CC2640R2F-CC2640R2-Current-consumption-in-standby-mode

e2e post and i am able to achieve approx 1.7 uA to 2 uA current between two advertise (30 sec is interval i have set ) on launch pad and Jorgin module but we are using in house design module with 5mm x 5mm size chip(Same chip used in Jorgin) which doesn't have 32KHz crystal so i build same simple peripheral example as "FlashROM_StackLibrary_RC_OSC" configuration but in this module i am getting 8 uA current.

So issue is that approx 6 uA current is more consuming.

Please let me know is there any extra setting need to do in firmware for this ? 

Also let us know which of the sleep mode is set in simple peripheral out of following.

Regards,

Bhavin
