Installation

Introduction

Don't be too concerned about the length of these instructions. Most is about setting up telemetry between INAV and your transmitter. If you're already sending telemetry, the first few sections will mostly be done. Also, I've tried to be very descriptive so even a novice could follow along, therefore it's a bit verbose.

For upgrades from a previous version, see the (much shorter) upgrade instructions

INAV Configurator Telemetry Setup

1. Setup SmartPort(S.Port), F.Port or D-series telemetry to send to your transmitter - INAV telemetry docs
2. If you have an current sensor, in CLI settings set battery_capacity to the mAh you want to draw from your battery
3. Set the fuel unit to output the percent:
   • If running INAV v1.9.0+: set smartport_fuel_unit = PERCENT in CLI settings
   • If running INAV previous to v1.9.0: set smartport_fuel_percent = ON in CLI settings
4. If using pilot or radar view and INAV v2.0.0+, set frsky_pitch_roll = ON in CLI settings for accurate attitude display and pitch angle

Add Telemetry Sensors to Transmitter

1. With battery connected and after GPS fix discover telemetry sensors so all telemetry sensors are discovered
2. Telemetry distance sensor name 0420 (or 0007 with D-series receivers) should be changed to Dist and set to the desired unit: m or ft
3. The sensors Dist, Alt, GAlt and Gspd can be changed to the desired unit: m or ft / kmh or mph
4. If you set frsky_pitch_roll = ON on INAV v2.0+ (which I suggest) you can optionally change the following for clarification:
   • Telemetry sensor 0430 (or 0008 with D-series receivers) can be changed to Ptch
   • Telemetry sensor 0440 (or 0020 with D-series receivers) can be changed to Roll
5. Don't change Tmp1 or Tmp2 from Celsius to Fahrenheit! They're not temps (used for flight modes and GPS info)

Add Lua Telemetry to Transmitter

1. Download the latest LuaTelemetry.zip file (Note: NOT the source code)
2. Copy the contents of the ZIP file (SCRIPTS and WIDGETS folders) to the transmitter's SD card's root
3. For Taranis transmitters: In model setup, page to DISPLAY, set desired screen to Script and select iNav

Using Lua Telemetry

• Taranis:
  1. From the main screen on your transmitter, long-press Page (down d-pad on X-Lite)
  2. If Lua Telemetry isn't on your first page, short-press Page till Lua Telemetry appears
• Horus as one-time script:
  1. From the main screen on your transmitter, long-press SYS
  2. Short-press PgUp/Dn which views the SD card contents on the Transmitter
  3. Locate the iNav script by selecting: [SCRIPTS], [TELEMETRY] then iNav.lua
  4. Select Execute to run the script

To use as a widget on Horus transmitters, see Installation: Horus Widget

Controls

• To change Lua Telemetry configuration, press Menu (Shift on X-Lite, SYS or Horus)
• It's a good idea to reset telemetry between flights by long-pressing Enter/dial and selecting Reset telemetry
