Hi,
I am working on a project where I need to reduce the power consumption as much as possible; So I found that when I set the extended sleep mode at the init part of the project(DA1458x_SDK\5.0.3\projects\target_apps\ble_examples\prox_reporter\Keil_5: user_config.h ,app_default_sleep_mode=ARCH_EXT_SLEEP_ON; ),the power consumption will be about 60uA(average),connecting with my phone will be about 300uA(average),and all the funcitons that I add in the project are working perfectly.
But the question is when the whole project working after a night or so ,the power supply will run up to 400+uA(average).And if I don't connect the blue ,the value lasts forever. And the interesting thing is nothing of my functions is affected ; The Bluetooth signal is ok; The connection between the board and my phone is ok ; The whole funcitons are nicely as is nothing happened in the whole project;
And another interesting thing is that when I use my phone to connect the board through the bluetooth singnal ,the power consumption is restoring to the normal level about 300uA(average),and when I disconnect the board ,the value is again to the 60uA(average);
I want to know why is that ?
Is there something wrong I might do?
Can anyone who knows something tells me somthing please..........

Continous high energy consuming in da14580 on extended sleep mode

Hi JerrickLee,
I am not able to follow your description or assume why the device after some time it consumes more power, i will just mention a few facts of the BLE protocol and perhaps you can correlate that with your device's behaviour. So, how much power you consume depends on how often your have BLE activity, how often you advertise or how often the devices have arranged a connection interval in order to communicate. So if while connected the power of your device gets increased after a few hours of operation perhpas there is a parameter update that forces the device to establish a connection with short connection intervals, or there are interactions that prevent your device from sleeping between the connection intervals (interaction with sensors memories etc). Or there is a leakage to your board, a pin configuration that happens under a specific occasion that causes the increased power consumption. As i ve mentioned earlier i am not able to correlate an increased power consumption with the fact that you just run for a few hours you will just have to check what the device actually does when the power consumption increases.
