impload - iNav Mission Plan uploader

Introduction

impload is a cross-platform command line application to upload missions in a number of formats to an INAV flight controller. "Alien" formats may also be converted to MW-XML. Supported formats include:

MW XML mission files (as used by mwp, inav configurator, ezgui, mission planner for inav)
apmplanner / qgroundcontrol mission files (qgc plan mission and survey at least (QPC or JSON).
GPX files (tracks, routes, waypoints)
KML, KMZ files
Plain, simple CSV files
mwp JSON mission files]
inav cli wp stanzas

Serial devices and TCP are supported for upload / download to / from flight controllers.

Please see the user guide for more information.

Usage of impload [options] command [files ...]
Options:
  -a int
    	Default altitude (m) (default 20)
  -b int
    	Baud rate (default 115200)
  -d string
    	Serial Device
  -fmt string
    	Output format (xml, json, md, cli, xml-ugly) (default "xml")
  -force-land
    	Adds RTH / Land for 'external' formats
  -force-rth
    	Adds RTH for 'external' formats
  -rebase string
    	rebase 1st WP to location (as lat,lon[,wpidx,segidx])
  -s float
    	Default speed (m/s)
  -v	Shows version
  -verbose
    	Verbose
  command:
	Action required (upload|download|store|restore|convert|test|clear|erase|multi[=n])

Device Name

impload supports the mwp device naming scheme:

serial_device[@baudrate]
tcp://host:port
udp://remotehost:remote_port
udp://local_host:local_port/remote_host:remote_port
xx:xx:xx:xx:xx:xx (raw BT socket, Linux only)

The baud rate given as an extended device name is preferred to -b

For ESP8288 transparent serial over UDP (the recommended mode for ESP8266), the latter form is needed.

Device name examples:

/dev/ttyUSB0@57600
/dev/ttyACM0
COM17@115200
tcp://esp8266:23
udp://:14014/esp-air:14014
# both sides use port 14014, remote (FC) is esp-air, blank local name is understood as INADDR_ANY.

Use Cases

Plan missions in apmplanner2 (QGC WPL 110 text files), upload (& save) to INAV
Plan missions in qgroundcontrol (JSON plan files), upload (& save) to INAV
Plan missions an any GPX creating GIS tool
Plan mission in Google Earth, save as KML path, upload to the FC
Convert "alien" formats to MW-XML.
Move a mission to a new location

Install

Binaries in the Release area (FreeBSD, Linux, MacOS, Win32) if you don't want it build it locally.

Command summary

upload : upload mission to FC volatile memory
store : upload mission to FC volatile memory and stores in EEPROM
download : downloads mission from FC volatile memory
restore : restores mission from EEPROM to FC volatile memory and downloads the mission
convert : converts alien formats to MW-XML (default), or the format defined by the -fmt option.
test : tests communications with FC
clear : clear mission in volatile RAM (specifically, uploads a mission with just a single RTH WP, which is always safe).
erase : erases mission in EEPROM and clears mission in volatile RAM (specifically, uploads and stores a mission with just a single RTH WP, which is always safe).
multi, multi=n : inav 4.0+; gets / sets the nav_wp_multi_mission_index value.

Build Instructions

Go infrastructure, unmodified source

go get github.com/stronnag/impload, binaries endup in go/bin, source in go/src/github.com/stronnag/impload. Requires go and git.

Local compilation (e.g for local modification)

git clone https://github.com/stronnag/impload

Files sources where ever you wish.

Simplest: make (or make install)
Windows (native): make nocgo (probably). You can also use the nocgo target on POSIX to generate a dynamically linked executable (vice the default static executable).

Note that you can cross-compile for any OS / architecture supported by Go using the GOOS and GOARCH environment variables, e.g for Win32 on Linux riscvs64:

$ uname -a
Linux jagular 5.15.2-cwt13 #2 SMP PREEMPT Thu Jun 1 14:42:43 +07 2023 riscv64 GNU/Linux
GOOS=windows GOARCH=386 make clean nocgo
rm -f impload
CGO_ENABLED=0  go build -trimpath -ldflags "-s -w -X \"main.GitCommit=0fa31fb / 2023-06-11\" -X \"main.GitTag=v5.161.652\""
$ file impload.exe
impload.exe: PE32 executable (console) Intel 80386 (stripped to external PDB), for MS Windows, 6 sections
