Hi Karan,

I saw your pvt msg, and I see that you are very keen to learn about this LBS service. The best way to learn is to put a breakpoint inside the funtion ble_lbs_on_button_change and start your program in debug mode. When you connect, bond, discover and enable services, you press the button. Then you will hit your breakpoint and see what data you are transmitting

params.p_data = &button_state;
params.p_len = &len;

button state is the value that is being shown as Invalid value.

If you want to debug it i recommend you to compile your code with zero optimization. . If you have problems then there are more helping users here on forum. It is always good that you are trying to learn new things.
