Can nRF51 be BLE connected while it's on sleep mode? (connected by other device as Peripheral mode)

Can nRF51 be BLE connected while it's on sleep mode? (connected by other device as Peripheral mode)

I thought, to be connected as peripheral mode, It must be advertising itself to be connected, because after a little bit of Advertising, the Accepter of peripheral mode will be turned on, and without this Accepter isn't turned on, the device cannot be connected.

In this point of view, a Node which want's to be connected as peripheral as any time(literally any time..) , could not sleep in any single time.

Am I thinking it right? Or does it can be turned on from sleep mode for connection request??

Hi Daniel,

There are two power modes in the nRF51 series; system on and system off mode. You can read about the differences in this thread.

When in system on mode, the chip will wakeup on any event, allowing to both advertise and keep a connection. Whenever there is something that needs to be handled, the chip will wakeup and handle the event.

There are a lot of threads about this, please search and read some of the threads!

Best regards,

Jørgen
