The notifications that are sent from the LBS client in components\ble\ble_services\ble_lbs\ble_lbs.c\ble_lbs_on_button_change is button_state which is one of the following from app_button.h file

So I think sending 0 and 1are valid values to be written. Probably you are not sending them as hex/dec numbers and sending them as ASCII?

Thank you Susheel.

I tried sending values other than 0 and 1, and in the app it shows "invalid value". Just wanted to confirm if this case is also a consequence of nRF connect mobile app implementation.

[quote user=""]Can you tell where the strings corresponding to the button states added in the SDK?[/quote]

I think there are no strings (Button Pressed/Button Released) in the SDK code in itslef. I think it is the nRF Connect mobile APP that is doing this magic of converting 0/1 value on that characteristic to Button Pressed/Button Released
