Adds audio feedback (just as the LED flashes) with each received packet.
My patches are for "devel" as I havn't been working on "dev2" yet.
Pitch of tone is at 440Hz currently.
For the two boards I own, I put one lead of the piezoe speaker on ground at the other on a spare GPIO:
Lilygo TTGO LORA32 2.1_1.6, GPIO 4
Lilygo TTGO T-Beam With display added, GPIO 25
This also bumps up the filesystem version from 17 to 18 as it modifies two files on the device. You can upload the full binary image, or just do the code update and manually edit the two files using the built editor:
http://x.x.x.x/edit.html?file=cfg.js
Insert next line after "led_pout"
[ "piezoe_pout", "Piezoe output port"],
http://x.x.x.x/edit.html?file=config.txt
Insert next line after "led_pout="
piezoe_pout=-1
I also had to do a cold reboot for the system to recognize a new configuration item. You'll need to then populate the GPIO for piezoe_pout to a free GPIO for your device (as above) in the web page configuration. You'll know it's working if you hear a 1 second beep during startup.
