current consumption of the radio Module in sleep mode

[MeisterBob]

Hello,

I am developing an IEEE802.15.4 Beacon with the nRF52840-DK, SDK 16 and the nRF-IEEE-802.15.4-radio-driver. My problem is that the consumes ~400uA of current in sleep mode, deiniting the driver doesn't make a difference. With Radio disabled the DK uses ~10uA with a 400uA spike every 28ms.

Can you please help me with reducing the current consumption?

Thanks
