LRSSI
The ALTITUDE value is reported as Above Ground Level. The ground level is set to the first altitude
telemetry value received.
The LQI (Link Quality Indicator) and LRSSI (Local RSSI) indicate the quality and signal strength of the
telemetry signal from the receiver. The LQI can be used as a guide for adjusting the fine frequency protocol
option. Lower LQI is better and values under 50 are typical. The LRSSI units is (approximately) dBm.
Derived values: MINCELL is the lowest reported CELL value. ALLCELL is the total of all reported CELL values.
Discharge is total battery discharge amount in milliAmp-hours.
10.16 Protocol: *Skyartec
The Skyartec protocol is used to control Skyartec™ receivers and models. NOTE: This protocol requires the
addition of an ‘CC2500’ hardware module to function. See the following document for more information:
http://www.deviationtx.com/wiki/#hardware_modifications
The Skyartec protocol supports up to 7 channels, does not support auto-binding. If Fixed ID is set to None,
a transmitter-specific ID is used instead. It is necessary to manually bind each model before the first use.
10.17 Protocol: *Futaba S-FHSS
The Futaba S-FHSS protocol is used to control Futaba™ receivers and models. It also used by some models
of XK Innovations and has third party compatible receivers available. NOTE: This protocol requires the
addition of an ‘CC2500’ hardware module to function. See the following document for more information:
http://www.deviationtx.com/wiki/#hardware_modifications
The S-FHSS protocol supports up to 8 channels, and only supports auto-binding. If Fixed ID is set to None,
a transmitter-specific ID is used instead. It is necessary to manually bind each model before the first use.
Traditional Futaba channel layout is following: Aileron, Elevator, Throttle, Rudder, Gear, Pitch, Aux1, and
Aux2. So it is suitable for control of Collective Pitch (CP) helicopters.
Protocol resolution is 1024 steps (10 bits) out of which a bit smaller range is actually used (data by reverse
engineering using third party equipment). Temporal resolution is 6.8ms. No telemetry supported.
10.18 Protocol: *V202
The V202 protocol supports the WLToys V202 quadracopter. NOTE: This protocol requires the addition of
an ‘NRF24L01’ hardware module to function. See the following document for more information:
