HowToSimulateInFlightMSPData.txt

Simulate real flight with INAV
On Linux.
Start inav_configurator, on SITL tab, setup without any external software, no RC COM.
Start it, then connect to it, configure with the plane config, then make all sensors to FAKE:
in CLI:
feature GPS
feature VBAT

set acc_hardware = FAKE
set baro_hardware = FAKE
set gps_provider = FAKE
set vbat_meter_type = FAKE
set current_meter_type = FAKE
set mag_hardware = NONE
set receiver_type = MSP
set rssi_source = MSP
set init_gyro_cal = OFF
set failsafe_stick_threshold = 0

save

stop inav_SITL and start in simulator mode:
./src/inav-conf/inav-configurator/resources/public/sitl/linux/inav_SITL \
  --path="/home/home/.config/INAV Configurator/msposd.bin" \
  --sim xp \
  --simip 192.168.1.66

Assuming MSP DisplayPort is setup on COM4. To map it, run:  
socat PTY,link=/tmp/inav_pty,raw,echo=0 TCP:127.0.0.1:5763
Run msposd:
./msposd -m /tmp/inav_pty -d -r 1030 --ahi 4 --matrix 11 -v

on Windows (192.168.1.66), start sending recorded sensor data:
G:\RC_model\INAV\Logs\fl2x\win64-x86_64\bin>fl2sitl.exe -verbose 3 -nostart -auto-arm "G:\RC_model\INAV\Logs\LOG00007.TXT"
  
enjoy!
