Custom Board_Ext sleep current

在dsp设备项目,一旦数据TX掌握鳍ished , we have put DSPS Device for 5 min sleep , i am able to see device is not advertising for 5 min , after 5 min only DSPS Device is advertising. so sleep is working properly , isn't ??

i2c driver for Temperature & Humidity sensor , ambient light sensor..

As you said if Hardware issue , why in DA14583 IOT kit also i am getting the same , (By connecting multimeter , to the on / off switch of Smart band IOT BLE board , battery end ti multimeter positive , ckt end to mutimeter com)

Thank you Dialog

Hi Dialog

PFA. power profiler graph

Thank you

Hi Wisilica

Thank you for your reply.

Then How DA14583 IOT smart Bond kit will give 11ua , does this also using the "cut off spi supply" configuration.. please give me some more details ...

i2c sensor have 10k pullup , will this cause any issue ?? ... How to resolve these ...?

thank you

As mentioned in the above post , will secondary bootloader fix this issue (for DA14580) ??

Thank you.

Hi Dialog

How to use spi_flash_power_down() in DSPS device project (for both DA14580 and DA14583 ), Is there any sample project or Document ??

PFA for the external peripherals in my custom Board , i am using this battery level monitoring also in DSPS ,

I have two custom Boards , One with DA14580BLE , another one with DA14583 , if SPI flash drawing more power , why both custom boards current consumption almost same ??custom Board with DA14583 should show less , Right?

Hi Dialog

https://wenku.baidu.com/view/20871b8127d3240c8547efd2.html
i have followed above link to use spi_flash_power_down() in DSPS_Device, but not working,...

From Beacon project , after every read / write operation spi_flash_power_down() got invoked , but in DSPS Device project i am not doing any read/write to SPI Flash, so exactly from which function i have to invoke this spi_flash_power_down() , so it will make sense.

Than you

Hi Dialog

Q 1 . In Our custom Board DA14580 - with external flash , i have removed all pullup register(10k) , and tested , i can not able to flash / erase SPI memory via SmartSnippets , if i put pullup in CS pin , it is working, But in beacon and smart tag designs i am not seeing any pullup in cs pin ??

Thank you Dialog

Hi Dialog

thank you Dialog , Now i can able to use the SPI flash without pullup register.

In DSPS device project
if i invoke spi_flash_power_down() inside periph_init() in "user_periph_setup.c" , i flashed this code , my device is not advertising after some time , also after this while erasing spi flash i am facing errors , In IOT project , spi_flash_power_down() invoked while reading/writing config parameters , but in DSPS how to use this API ?

Thank you Dialog

Hi Dialog

As you suggested , i am invoking the spi_flash_power_down() , in user_on_init()

void user_on_init(void)
{
// SPS application initialisation
user_scheduler_init();

default_app_on_init();
da14580_spi_flash_init();
da14580_spi_flash_deinit();
}

void da14580_spi_flash_init(void)
{

SPI_Pad_t cs_pad_param;
int8_t man_dev_id = 0;

cs_pad_param.port = SPI_EN_GPIO_PORT;
cs_pad_param.pin = SPI_EN_GPIO_PIN;

man_dev_id = spi_flash_enable(cs_pad_param.port, cs_pad_param.pin);

if (man_dev_id == SPI_FLASH_AUTO_DETECT_NOT_DETECTED)
{
// The device was not identified.
// The default parameters are used.
// Alternatively, an error can be asserted here.
spi_flash_init(SPI_FLASH_DEFAULT_SIZE, SPI_FLASH_DEFAULT_PAGE);
}
}

void da14580_spi_flash_deinit( void )
{
spi_flash_power_down();
}
but still i am getting 235ua during ext sleep
As menitone din smart_tag project , i have changed user_periph_setup.c

Also i have undef the #undef CFG_DEVELOPMENT_DEBUG
Removed the pullup in cs pin of EXT-SPI flash .

i have checked the same project in dev board , still 230uAmps , so i dont think hardware leakage is causing the current consumption

what could be the problem..........??what are the other options

Thank you

Hi Dilaog team

Thank you for your reply..

have you tried remove the UART connection and check if this drops your current consumption ??
Q1:如何删除,你的意思是在periph评论_setup.c ??

Q2: i have enabled spi_flash_power_down , in DSPS_DEVICE project , i am getting sleep current 160ua , if i disabled 176ua , i am not seeing big differences...

Q3: As you said if some other leakage is there in custom board , how to measure or find the leakage

Q4: i have used some unused GPIO pin as test points , will this cause any leakage ??

Q5 : in RFIOp for matching we have added 1.2pf and 3.9nh discrete components (in the PI network , R3 -> 1.2pf , R4 -> open , R5 -> 3.9nh) , will this cause any issues ??

Q6 : In ext sleep mode - i2c gpio are high , i am getting 3v , was it an issue ? if yes can i drive low ??
