can I advertise with this short power?

First, set nRF52832 to beacon mode.

Then, can I advertise with this short power?

Hi Jim

First off I am hoping you intend to regulate the voltage, if it is really > 6V like the plot implies :)

The SoftDevice takes a while to start up, and I am not sure you will have sufficient time during the peak of the pulse to start the SoftDevice and start beaconing.

You could take a look at the solar beacon example, which was designed to bypass the SoftDevice to do beaconing as quickly as possible after wakeup:
