https://devzone.nordicsemi.com/f/nordic-q-a/20524/where-is-the-code-of-reading-battery-levelHi Nordic team, I print logs at each function in ble_bas.c. I used the App of nRF connect to test BAS. I can see on_connect, on_disconnect and on_write at enabling/disabling notification. I cannot see the code of reading battery level when I presseden-USTelligent Community 13Fri, 24 Mar 2017 09:54:10 GMThttps://devzone.nordicsemi.com/thread/80020?ContentTypeID=1Fri, 24 Mar 2017 09:54:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2a62c817-b5e9-49c5-946b-bbf8b2dcf9bbrun_ar<p><a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.api.v4.0.2/group___b_l_e___g_a_t_t_s___r_e_a_d___r_e_q___n_o___a_u_t_h___m_s_c.html?cp=2_3_0_1_1_2_4_3_14">The read</a> will be handled by the softdevice.

I can get battery level correctly when I press the button (read battery level, please see the attach file in red circle) on APP. But I cannot see the source code of reading battery level in ble_bas.c. I want to know where it it. Enabling/disabling notification will run the function of on_write. Which function will be run if I read the battery level from APP? Thanks you very much.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/80018?ContentTypeID=1Thu, 16 Mar 2017 12:22:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bd49780d-59c0-4162-8580-5c1483cd580brun_ar<p>The battery is emulated so the actual code to &quot;measure the battery level&quot; is in the function battery_level_update which is called from the battery_level_meas_timeout_handler.</p> <p>However we have an example that shows how you can do battery measurements on the nRF51 <a href="https://github.com/NordicSemiconductor/nrf51-ADC-examples/tree/master/ble_app_hrs_adc_battery_measurement">here</a>.</p><div style="clear:both;"></div>
