Where is the code of reading battery level?

[Ted]

Hi 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 pressed the button of reading battery level on APP. But I got the battery level correctly. I want to know where the source code of reading battery level is? Screenshot1.png

The battery is emulated so the actual code to "measure the battery level" is in the function battery_level_update which is called from the battery_level_meas_timeout_handler.

However we have an example that shows how you can do battery measurements on the nRF51 here.

I am tracing the source code of ble_bas.c in SDK11. 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.

The read will be handled by the softdevice. If the peer perfomes a read it will simply reply to that without notifying the application. It is possible to use authorization if wanted.
