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?
