hi ;
now after i maked a successful connection between smart phone and nrf51822 and i could change the state of gpio pin 20 i find a new problem
i want my pin is still an state high until 3 secondes after that, it change its state to low, when i aded a timer to my code something weird happened, the adevrtising stopped i can't find my ble with my smartphon and the code don't work any more until i elemeiminate start_timer () (comment it)
i'm using sdk9 nrf51822 pca 20006 with s110

* @brief BLE Services, a beginner's tutorial project main file.
*
* This example is meant to be used togheter with the tutorial "BLE Services, a beginner's tutorial"
* found at https://devzone.nordicsemi.com/tutorials/8/ble-services-a-beginners-tutorial/.
* The purpose of this tutorial is to get you started with the basics of the nRF51x22 and Bluetooth Low Energy (BLE).
* More specifically this tutorial will go through the bare minimum of steps to get your first services
* up and running. The tutorial is fairly superficial and is meant to be a hands-on introduction to BLE services.
* It is intended to be a natural continuation of the tutorial "BLE Advertising, a beginner's tutorial".
* It can easily be used as a starting point for creating a new application, the comments identified
* with 'OUR_JOB' indicates where the work described in the tutorial needs to be done.
