Hi,
My task is..
Device will advertise for 20 seconds if there is no connection then it will go to sleep mode for 40 seconds. After 40 seconds it will wake up from sleep mode using timer interrupt and start advertising again for 20 seconds, This cycle continuously runs until device makes BLE connection.
I want to enable sleep mode and minimize current consumption in sleep mode.
I have used following APIs to put device in sleep mode.
sd_power_mode_set(NRF_POWER_MODE_LOWPWR);
sd_app_evt_wait();
But even though, it is consuming 170-230 uA current in sleep mode.
Any idea how we can reduce current in sleep mode. Is this correct method to enable sleep mode with SYSTEM ON ?
I have attached Main.c file of my code. Sleep_mode_enter function is used to enable sleep mode when advertising IDLE event triggered from softdevice.
Please let me know as soon as possible.
/* @file main.c
* @brief custom BLE project main file.
*
* This file contains demo application which uses custom BLE service and characteristic.
* custom service has functionality of read/write characteristic value and notification
send at interval of 1 second.
