So, the nRF51 remains in sleep mode until woken up by bluetooth of a nearby device, that wants to pair with it. This means that radio of the nRF remain active even during sleep. Is this possible?

Yes, the nRF51824 uses the S130 SoftDevice BLE protocol stack solution, which is Bluetooth 4.2 compliant.

What do you mean by wake-up from paired device?

That helped a lot, thanks. But, does it support Bluetooth 4.2? The product specification document does not clearly say so. Does it support wake-up from paired device?

While in a active BLE connection, the chip will typically be in System On mode. During CPU sleep, it will be in the System On low power sub power mode. In low power mode the automatic power management system ensuring the most efficient supply option is chosen to save the most power. See the nRF51 series current consumption guide for more information. The nRF51824 Product Specification can be found here. This excel sheet for power consumption for the nRF51 series made by devzone community user Freddy Sørensen can also be helpful. The nRF51 Reference Manual can be found here.

Thanks for that. Would you be able to specify the following wrt 824?

Support for Bluetooth wake-up,

Sleep mode operating current while supporting Bluetooth wake-up,

Normal operating current

Hi,

The nRF51824 is automotive grade AEC-Q100 qualified (Grade 2: -40 to 105ºC). So if you need your SoC to be AEC-Q100 qualified, you should use the nRF51824. More information about the nRF51824 can be found here.
