[WP76xx] AT!avtoneplay latency

Hi All

we connect a digit keyboard to our host, when we push digit button(0-9), we can using at!avtoneplay=0,x,200 to play tone voice.

Now , we found the at!avtoneplay command has latency about 2 seconds, it’s too long.
For example, if you use a mobile phone, the input number is very fast, and you can hear the tone in time.
I think if the letency can reduce to 200ms, it’s better.

Does anyone have some suggestion?

Hi @okqqkimo1
After I check tone voice by using at!avtoneplay=0,x,200 on WP76xx, I see that the at!avtoneplay command hasn’t latency.

I think that the issue occured in your application. Could you review the process of application when you push digit button(0-9) from digit keyboard?
