Aryan,

Thanks for the reply. Would Nordic consider modifying the SDK in a future release to of the user_function() return an error code that would be tested in the while loop? This why a timeout could be completed implemented in user code.

Also, I'm not sure what you mean by "rather safe to configure the GPIO pin with a pull up rather than testing that this could be grounded by long term wearoff"

Thanks, Darren

wouln't it be rather safe to configure the GPIO pin with a pull up rather than testing that this could be grounded by long term wearoff?

That said, you can do something like this

app_timer_call_back()
{
      p_app_twi->internal_transaction_in_progress = false;
}

start_oneshot_app_timer_with_timeout
while (p_app_twi->internal_transaction_in_progress)
{
    if (user_function)
    {
        user_function();
    }
}
stop_app_timer
