Extern Sleep Mode Current

嗨多米南，

你不需要设置anything else in order for your device to go into sleep mode, the current that you see could be either from the debugger that is still attached on the 580 (stop the debugging in order for module to stop drawing current), also could be that the device doesn't sleep (you haven't set the proper flag ARCH_EXT_SLEEP_OFF or your fw is keeping the device awake), the last reason that something like this could happen is if something else drawing power from your circuit and not the 580.

嗨多米南，

What i mean is that while your code runs and the debugger from keil is attached the module will consume extra power, so in order to stop this from happening you will have to exit debugging mode from keil. Also the power consumption of the 580 is ~1.5uA when the device is sleeping, the proximity reporter sleeps and wakes up in order to advertise or keep a connection alive, you will be able to properly measure the lowest value of your power consumption when the device sleeps constantly if not i suppose that your instrument is averaging the current that the 580 consumes including the radio activities. Please also check the Tutorial 5: configuring sleep mode on DA1458x in order to see how to properly measure the power consumption.

嗨mt_dialog：

I tried to define below in da1458x_config_basic.h in order to select deep sleep mode. Unfortunately, the power consumption is always ~500uA. What else I should do?

#undef CFG_EXT_SLEEP
#define cfg_deep_sleep.

I tried to follow up UM-B-006 DA14580 Sleep mode configuration v1.1 document, frankly speaking, this document is really hard to capture what is truly needed to enable sleep mode, should I modify main loop function? what else I should do to enable sleep mode beside the modification in da1458x_config_basic.h?

我当前的邮件循环只是重用SDK One，如下行。你能否建议我应该修改的其他东西可以启用14580睡眠模式？深度睡眠或延长睡眠对我来说没问题。

int main_func（void）
{
sleep_mode_t sleep_mode;
system_init（）;
而（1）
{
do {
schedule_while_ble_on();
}
while ((app_asynch_proc())); //grant control to the application, try to go to power down

if（（（！ble_app_present）&&（check_gtl_state（）））||（ble_app_present）））
{
global_int_stop（）;

app_asynch_sleep_proc（）;

sleep_mode = rwip_power_down（）;

if ((sleep_mode == mode_ext_sleep) || (sleep_mode == mode_deep_sleep))
{
arch_goto_sleep(sleep_mode);

WFI（）;

ARCH_RESUME_FROM_SLEEP（）;
}
else if (sleep_mode == mode_idle)
{
if (((!BLE_APP_PRESENT) && check_gtl_state()) || (BLE_APP_PRESENT))
{
WFI（）;
}
}
global_int_start（）;
}

if (USE_WDOG)
{
wdg_reload（watchdog_default_period）;
}
}
}

顺便说一下，我在哪里可以找到your mentioned "Tutorial 5: configuring sleep mode on DA1458x"?

Hi smdzj007,

You dont need to change anything in the main loop in order to have your device in deep sleep. To start with, the only thing you should do is to change (since you are using the SDK 5) in the user_config.h file the variable app_default_sleep_mode and leave everything else as is. Also in order to be able to measure the deep sleep current you need to burn you application in the OTP so the OTP mirroring and sysram shut down to execute.

The power measuring tutorial can be found in the Documents tab, in the tutorial section.

嗨多米南，

We are facing similar issue. The power consumption is ~370uA during extended sleep mode. How did you fix this?

Hi wisilica

在我的设备上发生了同样的问题，我使用SDK 5.04 Sleep_Mode演示应用程序，当系统在深度睡眠模式下时，电源累积为370UA，当ADV时，电源累积为410UA，我顺便问一下，即可插入JTAG连接器，

嗨内核，

Do you have the flash connected or if not the flash do you have any other jumpers applied on the J5 header (perhaps the SPI_SUP jumper) ?

谢谢MT_dialog

Hi Kernel,

how can I contact you? we have a local team to support Huami , we worked with Huami Hefei,Huami SZ , my mail :Jelphi.zhang@diasemi.com

问候，
Jelph
