Playing Toolkit Tones
You can test the audio path with the toolkit tones. These are tones that mimic what
some phone services sound like. For a full list of tones, you can check the AT+STTON
E command in the AT command datasheet. We'll use tone #20 which is the American
dial tone.
You can switch to headset mode, play a tone, then try it on the external audio mode.
This is a very easy way to try out both speakers for debugging
Phone Calls
Make Phone Calls
OK now we're onto the good stuff. You can make a phone call with FONA pretty
easily. Make sure you have the right audio interface selected (external or headset!)
