Any one can reply my question please ?

question :HOW can i calculate expected values from BLE power profiles? I don't have exact time duration of each stage (A, B ....) ?

Hi Kristin,

The code is basic, just initializing ADV and then start ADV and in while(1) loop i put the sd_app_evt_wait();, so i get peaks of advertising periodically as supposed to be, and the profile of each ADV event is exactly the same as in the nordic specification. The current consumption i found are logic, but not for the -30dbm

The current consumption numbers in the product specifications should be correct. Could you upload the code that you use for testing?

Hi Kristin,

Ok thanks for the clarification about the test level. the profiles i got are logic and conform to the nordic specification ;)

Measures :

1.TX power =0dbm : highest peak = 13.2mA lowest peak = 11.84mA

2-TX power =-30dbm : highest peak = 12.76mA lowest peak = 11.76mA

3.TX power =4dbm : highest peak = 16.56mA lowest peak = 16.36mA

Its not really logic comparing to the data sheet :/ (i mean when TX power =-30dbm, the others are fine)

The test levels are described at the beginning of chapter 8 ("Electrical specifications) in the Product Specification:

What is the current consumption that you measure in -30 dBm mode?

The profile of an advertising event can be found in the S130 softdevice specification, chapter BLE power profiles --> advertising event.
