Glossary¶
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 respectivelyOTX
: OpenTXFW
: FirmwareBL
: Bootloader, loads the FWS.Port
: SmartPort, sometimes referred to assport
. FrSky "telemetry" protocol. TheS.Port
also gets used for updating FrSky receivers.OTA
: Update your deviceOver The Air
(wifi)MCU
: Micro Controller Unit, generally denotes an embedded system controller as opposed to big iron cpuOSD
: On Screen Display, refer to this page for instructions for setup in BFLQ
: Link Quality, percentage of expected packets received. Our preferred method of measuring the quality of the control linkRSSI dBm
: Measure of power level measured in dBm. Basically, how strong the signal being received isRSSI
: Received Signal Strength Indicator, "arbitrary" scaled version ofRSSI dBm
or LQ. Signal Health: LQI and RSSI ExplainedLua
: 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.)
