nRF52832 Radio disable to minimize the power consumption

[Aditya Narayan Tripathi]

Hi,
     in our one project we are using nrf52832 radio to transmit the data packets. After transmitting the data packets, the nRF52832 chip need to disable the radio to minimize the power consumption because we are using a battery operated device. Once, if i enable the radio configuration and after successful packet transmission   I am unable to send the radio into off mode. it is always enable. How to disable the radio. following procedure i am using to disable the radio:

NRF_RADIO->EVENTS_END = 0U;
NRF_RADIO->TASKS_DISABLE = 1U;
NRF_RADIO->POWER = 0;
NRF_CLOCK->TASKS_HFCLKSTOP = 1;

I am  using SDK 14.2 ( Soft Device Version S132 5.0 ) with BL652 module. i am using windows 10 computer platform and  Kiel-5.25.2.0.

Do let me know if I am missing something. Let me know if you need any further information.

Regards

Aditya

Hi,

You cannot control the radio directly when you are using a SoftDevice. The SoftDevice handles the radio, and is highly optimized to only use it (and other resources) when needed to minimize power consumption.
