Hello Sir,
I am working with STM32WB55CGU7 bluetooth MCU for Client and server for our application.Our application is Client and server connect 3 minutes once for 20 seconds.I need to enable the sleep mode in this controller for reduce power consumption.Because Iam using Lithium iron battery to power on the board.So Need to use Battery voltage for long days. And I have included my doubts of 2 points. Please find and help me solve as soon as possible to achieve our Project.
1. We enable the sleep mode in this controller using inbuild functions. These functions are I have used,
PWR_EnterSleepMode();
PWR_ExitSleepMode();
Its working.
We test this scenerio,
| Initial Voltage(V) |
Time(Hrs) |
With sleep mode (V) |
VoltageDifference(mV) |
| 3.445 |
13.5 |
3.005 |
440 |
| Initial Voltage(V) |
Time(Hrs) |
Without sleep mode (V) |
VoltageDifference(mV) |
| 3.577 |
13.5 |
3.515 |
62 |
We faced, without enabling the sleepmode the voltage was drop minimum.
But when we enable sleepmode was maximum voltage drop. Is this function what we called is correct for enable sleep mode or anyother function need to be use.Kindly give me guidance for enable the sleepmode for STM32WB55CGU7 MCU.
2. If we use CR2032 battery for to power on the board and connect for 3 minutes once for 20 seconds means, What is the capacity of battery working?
These are all my doubts. Kindly find and help me to resolve our queries regarding STM32WB55CGU7 mcu.
Thanking you.
