Battery service & debug problem

Question

Hello, 
 I try to add battery service in ble_app_uart , but it has some problem. 
 The Problem is that I can see the Battery service on the phone , but it doesn't change by ADC . 
 the Operation is under SDK9 & s110 . 
 By the way , how to find errors in debug mode? 
 when i enter the keil c debug mode , i always see this situation following .
 
where can i see error? 
 Thanks.
--------------------Edit----------------------------------------------------------
My problem is that I can see the following picture if add the "APP_TIMER_INIT(......)" under the "timers_init()" in main loop.
But Battery level is always 100%.
 
 If i don't add the "APP_TIMER_INIT(......)" under the "timers_init()" , i can't find peripheral on phone. 
 This is my project .
 ble_app_uart.rar 
 Thanks.

Hi. You can see how to use the err_code and APP_ERROR_CHECK() here . 
 You should also be able to see the value of err_code if you look in the "Call Stack + Locals" field. 
 
 Do you get an error when you use the ADC? 
 EDIT: 
 It looks like your battery_level_meas_timeout_handler() timer is never called. This is because you are calling APP_TIMER_INIT() twice. You call it first inside timers_init(), as is standard procedure in the SDK. Then you create your battery timer with app_timer_create(). Then you call APP_TIMER_INIT() again, effectively overwriting the battery timer you just created. So the first thing you need to do is to uncommend APP_TIMER_INIT() in your main() function. If you start your debugger now you will see that ble_conn_params_init() returns an error. If you enter ble_conn_params_init() you will see that the error occurs when app_timer_create() is called. The returned error is error 4; NRF_ERROR_NO_MEM. This error is returned if the timer operations queue is full and what you need to do is to change 
 #define APP_TIMER_MAX_TIMERS (2 + BSP_APP_TIMERS_NUMBER) /**< Maximum number of simultaneously created timers. */
 
 to 
 #define APP_TIMER_MAX_TIMERS (3 + BSP_APP_TIMERS_NUMBER) /**< Maximum number of simultaneously created timers. */
 
 In your main file. This will allocate more memory to the app timer module.
