@m5stickfreakler said in Speaker beep and Wait:
This Code generates no sound or an endless sound but not the expected 1/16 beep each second
This flow has issues because it's trying to fire a timer callback at the same time as the 1 second wait, which causes a blocking function. I do get a continuous beep as you describe, but I don't think it's a bug. I would consider it bad code design because you have two functions at 1 second firing at the same time, which causes blocking. You really only need the timer and not the 1 second wait function to achieve a beep ever 1 second.
