Only BLE sleep and wake-up sequence control in a nRF52832, while CPU running in normal mode

[jinvers]

Hello,

For the development of a new device I am using a custom hardware with a nRF52832 chip. I am working over the nRF5_SDK_17.1.0 using the SES IDE environment.

As a controller, the nRF52832 manages a state machine for acquiring some data from an SPI sensor and storing this data in a SPI flash. I only need to connect the device by BLE during some specific moments.

So, for increasing the autonomy of the small battery the device has, I would need that the CPU could run in normal mode while the BLE should be sleep. And wake-up the BLE in a controlled way in those specific moments. And after having transmitted the information, I should put the BLE services to sleep again.

Do you know of any example that could help me for managing this?

Thank you very much in advance.

Regards,

Joel

May be. It's difficult to say because there is more HW in the middle. I have to check it better.

Sounds good. One other thing, though. Remember to not debug while measuring the current consumption. So if you have been debugging, you should do a reset before measuring current consumption, and make sure to not attach a debugger.

Thanks Einar. I have found this.
