Designing for Low Power and Estimating Battery Life for BLE Applications provides average current for both advertisement and connection event. Isn't that sufficient?
@Undesh: Thank you for the response.
The application note mentioned 'Designing for Low Power and Estimating Battery Life for BLE Applications' provides an excel macro sheet which estimates average current given IMO frequency, crystal tolerances, and advertising or connection interval. The PDF includes a measured oscilloscope cursor trace (Figure 9/10) which shows the time length of the BLE event.
I still don't see a piecewise reference like what Nordic provides with expected current and time length. I do not understand stage reference provided in this document in Table 14 'A-J' as it does not match with the reference Figure 9.
I've measured a 5.61msec packet with 7.09mA draw for advertising. And a 3.13msec packet with 4.56mA draw for connection. These roughly compare to what the excel macro sheet provides of 41 and 15.6 uA respectively for advertising and connection events but a much larger error exists between expected and measured as compared to the Nordic nRF51 comparison.
Is it best to file a request with Cypress Application Engineers for this information?
Some other questions that are relevant to this discussion:
1) Does effective ON-time of MCU during BLE advertising or connection event vary with changing IMO clock frequency?
