Below you can find a list of terms you might not be sure about, as well as some common abbreviations:
CRSF: TBS Crossfire, more specifialy in our case most often refering to the communication protocol between TX and TX module and RX and FC respectively
BL: Bootloader, loads the FW
S.Port: SmartPort, sometimes referred to as
sport. FrSky "telemetry" protocol. The
S.Portalso gets used for updating FrSky receivers.
OTA: Update your device
Over The Air(wifi)
MCU: Micro Controller Unit, generally denotes an embedded system controller as opposed to big iron cpu
OSD: On Screen Display, refer to this page for instructions for setup in BF
LQ: Link Quality, percentage of expected packets received. Our preferred method of measuring the quality of the control link
RSSI dBm: Measure of power level measured in dBm. Basically, how strong the signal being received is
RSSI: Received Signal Strength Indicator, "arbitrary" scaled version of
RSSI dBmor LQ. Signal Health: LQI and RSSI Explained
Lua: Means "Moon" in Portuguese. As such, Lua is the correct way to write and not all uppercase. The ExpressLRS Lua script can be installed on a OpenTX radio, to easily alter TX parameters like Packet rate, Telemetry ratio and Output power. But also shows if the radio (OpenTX) is communicating correctly with the module. ( e.g. 0:50, 0:150, 0:200 and so on.)
