RE: Nordic SoftDevice Controller versus Zephyr BLE Controller (CONFIG_BT_LL_SW_SPLIT=y)

Thanks Susheel for your answer and hint with the config. I've played around with several settings but in the end I was switching back to the softdevice controller, cause is was more power efficient and battery power is most important in our project.

Best Regards,

I think Softdevice controller is little better power efficiency wise, that is why we keep recommending customers to use it. But when you choose Zephyr controller, I think some of the default configs change for other parameters. Best to compare the ".config" file in the build folder with these two different configurations and see if you need to fine tune some of the parameters relevant for BLE.
