Hi dialog

I m working on custom baord based on DA14681. I want to know how to go into sleep mode and how to set a synchronous timer to wakeup automatically.

Actually my application needs that device automatically wakesup after every minute, read ADC temperature, writes to flash and go back to sleep. I want to know is there any example code where this kind of sleep is implemented. Or if you can help me for this?

Secondly device must also be availble for SUOTA update or BLE data transfer. Please tell how that can be managed while sleeping?

Maximum connection interval

Hello,
I'm using PRO board and SDK 5.0.4. I'd like to set a large connection interval to reduce power consumption. Based on ble_peripheral project, I change parameters in user _config.h. When I change the interval to around 300ms, it works and I can see the waveform using powerprofiler. However, when I set the connection interval further to around 3.6~4.0s which is the limit according to BLE specification, the actual interval is still 30ms. This is my user.config.h: (I didn't change other places)

GPIO state during sleep during BLE connection

Hi,

I am having a very strange issue.

I am using an ADC channel on Port 0, Pin 1.
This line has a very weak pull down to 0V (about 1.5M).
During advertising, this pin happily sits at 0V whether the DA14580 is running or in sleep.

However, once a Bluetooth Connection has been made when the DA14580 goes into sleep, Port 0 Pin 1 goes to about 750mV.
