If you navigate your mouse over an input field / button, you see a detailed description what it does / which values are expected.
Info for SNR/RSSI path encoding
If enabled, add SNR and RSSI in path on receiption, prefixed with 'Q'. Examples:
SNR 23 RSSI -73 -> Q2373
SNR -03 RSSI -104 -> QA3K4
SNR -13 RSSI -114 -> QB3L4
Still testing, if it behaves good to our network.
Use with care; resulting longer path consumes a bit more airtime.
User key functions (hardware buttons):

Hardware notices
TTGO LoRa32 V2.1 (aka T3 V1.6.1)
Hardware limitation: if bluetooth is enabled and BT-client is connected, WIFI (-> Web-Server) does not work anymore.
You'll see the red LED while booting turned on for 60s as indicatior for waiting for BT-clients.
Hack: firmware compiled with -e ttgo-lora32-v2.1 and bluetooth configuration variable is set to enabled, now listens on boot up to one minute for your bluetooth device to connect.
If a bluetooth device connects, it does not start the Web-Server. Else, it closes SerialBT port and starts the Web-Server on LORA32_21 devices.
See also: new feature for switching WIFI off (i.e. if you use the device as portable tracker), if you don't need it: Webserver eats abt 80mA..
