nrf52832: Wakeup from sleep mode on radio reception

[Dinesh]

Hi,

Greetings!

We are about to select nrf52832 for our product development and we need confirm below information before proceeding further

Overview

Device will be powered by coin cell battery say CR2032

Most of the times it will be in sleep mode

It will work on Bluetooth SIGmesh

And my question is

1. Does nrf52832 support wake-up on Bluetooth reception?

2. If Yes, please share a guidance /reference link

Regards,

Hi

When the nRF52832 is in sleep mode, both in system ON and OFF, the radio is disabled, so it will not be able to wake up by receiving a BLE event. What you can do, is either set a timer that wakes the nRF52832 up periodically to check for BLE events, or have a separate MCU with radio capabilities that can wake up the nRF when it detects a BLE event (This will likely be too power-consuming to be sustainable by a coin cell battery though).

Best regards,

Simon
