I am testing a custom CC2640R2F board, running an only-slightly-modified simple_peripheral project.
Analyzing the RF transmission, I see a pulse of 200 usec duration every approximately 100 msec. This what I expected to see for a connectable advertisement.
However, I also see a second pulse delayed from the first by approx. 400 usec and having approx. 400 usec width.
What is this second pulse? Is it part of the advertisement?
