nRF52811 used without Bluetooth functionality

[JsSenso]

Hi,

currently I am using nRF52811 in one product with BLE functionality. Now I would like to use the same MCU in other product where BLE is not needed.
In this case I would like to re-use part of the electronics and software which I already use.

So, is it possible to use nRF52811 without BLE functionilty (without SoftDevice and antenna periphery)?
If yes, how should prepare the hardware (pins: ANT, DEC2, DEC3) and software?

Thanks for any help, Jure

Hi,

Yes, it can be used for UART , SPI etc. and for some CPU processing. But you don't need to do anything with the hardware and can keep everything as it is. You can remove the antenna though as it is not needed.

HI, 

thank you for your response. Just to be sure, if not using Radio (BLE) I can leave ANT, DEC2 and DEC3 floating?

Hi,

ANT and DEC2 can be left floating, but DEC3 should have a de-coupling cap.
