Hi rushin

Thank you for your question and sorry for my late response on your case

When softdevice is enabled (as with the ble_app_beacon example) the nRF51 will periodically sleep between BLE events. Further info on how that works is given in the nRF51 current consumption guide, section "Low power mode with BLE softdevice"

In e.g. the ble_app_bps in nRF51 SDK 10.0.0, application timers are set up to periodically generate interrupts in the application. You need to do three things in your application to implement an application timer:

1. Initialize your timer, as done in timer_init() function in the ble_app_bps example
2. Start your timer, as done in the application_timers_start() function
3. Implement a timer callback function, as done in the battery_level_meas_timeout_handler() function

How to connect to the device with Master Control Panel is described in this tutorial, and also how to connect with your smartphone, in the section "Connecting to the nRF51 DK"

How much it is delay??
