FM2M ToolBox FAQ

Here you can find answers to most common questions

How to switch to FM2M ToolBox PRO version?

How to install ToolBox?

How to run ToolBox in stand-alone mode

  • Once flies are moved properly into your radio's SD card FM2M ToolBox will be available in TOOLS TAB of EdgeTX or OpenTX.
  • Shortcut to open TOOLS TAB is:
    * long left joystick press on FrSky XLite family radios
    * long press MENU key on other radios
    * long press SYS key on Color LCD radios & some BW Radiomaster radios 

How to run ToolBox in background mode (telemetry script)
on B&W LCD radios

How to run ToolBox in background mode (widget)
on Color LCD radios

  • Add FM2M TBOX widget to one of your main views
  • Set BGMODE in Widget's settings if you want to run ToolBox constantly in background.
  • Set STATUS in Widget's settings if you want to see ToolBox telemetry preview.
  • Double tap or select 'Full Screen' to open ToolBox
  • To go back to system long press EXIT key

ToolBox doesn't work. App starts but no data is displayed.

  • Most probably telemetry sensors are not discovered in your model configuration of EdgeTX or OpenTX.
  • On most B&W LCD radios
    1. press MENU button
    2. press PAGE button until TELEMETRY page is displayed
    3. scroll down (using +/- keys, dial wheel or roller) and find DISCOVER NEW SENSORS button
    4. Execute it pressing (pressing ENT key, pressing dial wheel or roller) and let sensors to be discovered

  • On FrSky XLite family radios
    1. long press joystick RIGHT
    2. press joystick RIGHT until TELEMETRY page is displayed
    3. scroll down pressing joystick DOWN and find DISCOVER NEW SENSORS button
    4. Execute it pressing joystick and let sensors to be discovered

  • On Color LCD radios
    1. press MDL button
    2. press PAGE NEXT or PAGE PREV button until TELEMETRY page is displayed
    3. scroll down and find DISCOVER NEW SENSORS button
    4. Execute it pressing (pressing ENT key, pressing dial wheel or roller) and let sensors to be discovered

  • Then run ToolBox App.
    Go to Config module navigate to to TELEMETRY page and select used RC Link (protocol) type.

    Once are sensors discovered and RC Link type set properly ToolBox Dashboard will and display all data

I've discovered sensors but I can't see all data
like Gyro mode (Stab, Horizon, Acro),
Current drawn or mAh consumed.

  • There are two kinds of Telemetry sensors:
    1. Receiver sensors
    2. Flight Controller sensors
  • To enable first one you just have to bind receiver to transmitter. Depending on RC link type usually sensors like RSSI, RQly or RX voltage will be available.
  • Second group of sensors need to connect Flight Controller and configure properly it's firmware (BetaFlight or EmuFlight) to send FC telemetry sensors via receiver to transmitter. Once you configure it sensors like Curr, Bat%, FM, or Capa will show up providing additional info about quad state.

I have configured FC telemetry
but still I can't see Gyro mode (Stab, Horizon, Acro)

  • Well that depends on RC Link type and how hardware supplier implemented protocol.

    * Gyro mode is available in FrSky D8/D16, CRSF & ELRS but not in Ghost
    * VTX status is available in  CRSF, Ghost but not in FrSky D8/D16 and ELRS
    * KISS is not supported yet. So you will see most data but not flight mode for example

    As soon as they are available I will include them in future releases.

I can't see my VTX status

  • First of all as for December 2022 telemetry VTX status is available for IRC Ghost and TBS Crossfire/Tracer protocols.
  • ToolBox's Dashboard will show VTX status when VTX protocol is properly configured both in Toolbox and in FC firmware (ie. BetaFlight).
    1. For Crossfire RX, VTX has to be one of TBS VTXs (Unify) connected via SmartAudio or CRSF protocol
    2. For Ghost RX, seems that any of IRC Tramp protocol capable VTX will work as VTX status is stored in Ghost TX module (need to be confirmed 100%)
  • From version 0.77 MSP protocol is available. Requirements:
    * FC with Betaflight 4.3+
    * VTX connected to FC and set to use
     - SmartAudio for CRSF and ELRS    
     - Tramp for IRC and Ghost

Can I see if my VTX is in Pit mode?

  • Yes you can.
  • On B&W radios VTX indicator in inverse mode shows you that VTX transmits with selected power while when VTX indicator has white background it means VTX Pit mode is engaged

  • On Color radios once VTX Pit mode is enabled VTX indicator background goes red

    Ghost RC Link note:
    There actually no Pit Mode, but you can set  0mW or 1mW. I'have coded anything below 1mW as PitMode.
    Additionally you can configure Ghost TX module to switch off VTX power completely using pre-defined channel. In this case Ghost protocol is not reporting switching off so ToolBox Dashboard indicator will not show PitMode. 

How to set Throttle limiter

  • Limiting throttle is done via Mixer configuration. LUA has access to mixer configuration but to avoid any misbehaviour mixer configuration is not coded.
  • Once you make manually proper Mixer configuration (video below) configure proper input (slider or trim) in ToolBox configuration to display Limiter value. 

Will you maintain Black & White LCD radios support for ToolBox?

  • YES. Even Color LCD radios open whole new horizon with better MCU, memory or TouchUI capability, good old FrSky X9D or the newest TBS Mambo or RM Zorro are very reliable radios and I find myself using them a lot. Surely due to above mentioned limitations as time goes by version for Color LCD radios will have more features.

Will you maintain support & development for OpenTX?

  • Well yes and no. I will maintain support (bug fixes) but new features are not implemented from January 2023.
    Last version compatible with OpenTX and FreedomTX is 0.82 

  • OpenTX due to lack of resources stalled and only maintenance is done. Seems that as of January 2024 OpenTX is slowly sunsetting.
