BLE Radio Current Profile
I'm trying to characterize power consumption on the CY8CKIT-042 BLE kit and compare performance against Nordic nRF51 and nRF52 for BLE radio events.
Does Cypress have BLE current profile for connection and advertising event? Nordic provides this data in the datasheet/product specification and Softdevice specification. I checked the PSoC_4_PSoC_4XX7_BLE datasheet and TRM and could not find the data. Do you guys have this internally and could share?
The application note "Designing for Low Power and Estimating Battery Life for BLE Applications" provides some reference but leaves a bit to be desired. Figure 9 and 10 are oscilloscope captures for advertising and connection event with sub time-periods referenced as alpha terms. Figure 21 and 23 are cartoon diagrams showing the different BLE radio modes and also if the Cortex M0 is active.
If I could have this figure with rough time periods for each mode and expected current consumption that would be great.
