low power with NRF52 serialization

[vincenttardy]

Hello,

We plan to use the Serialization mode with the NRF52832 module.

We would like to know how is handled the low power mode when the NRF52832 module is used in Serialization mode.

Do we modify the code embedded in the NRF52832 module to handle the low power or it is already automatically managed by the serialization Embedded code?

Thank you

What kind of low power mode do you mean? Could you explain a bit more?

[vincenttardy]

When we are using serialization in the nrf52 module (connectivity board), the main loop in the connectivity application calls the sd_app_evt_wait() function. This function seems to be defined in the SoftDevice stack.

Could you please tell us if the nrf52 mcu is setting in low power (_WFE ?) when the sd_app_evt_wait() function is called?

Moreover, when there is no Radio activity, could you tell us if the radio is setting also in a low power mode to reduce the consumption?

[Petter Myhre]

sd_app_evt_wait() will called __WFE yes.

When there is no radio activity the SoftDevice will put the radio peripheral into a low power state.

Thank you for your feedback. Now it's clear for us.
