How to resolve multiple buttons long pushed at the same time but only one button correctly detected based the example "ble_app_uart" of nRF5_SDK_15.2.0_9412b96?

Dear all,

       In my project, I add 3 long push action events related to 3 buttons by using " bsp_event_to_button_action_assign( )". Everytime I long push any of 3 buttons, the program can detect correctly. But when I long push more than 2 buttons at the same time, the program can only dectect one button as long push action event, and others are responsed as release button event.

     My project need to detect more than 2 buttons long push at the time, so how can I resolve the problem I encountered?

You can add your own logic with time duration & define pushbutton gpio either PULL_DOWN or PULL_UP. Check this: https://raspberrypi.stackexchange.com/questions/63512/how-can-i-detect-how-long-a-button-is-pressed
