Transmitters without WiFi modul

The first standard tx units ain’t got the wifi modul installed. If you got a micro tx, lite tx or a newer standard tx (since 2017) you don’t need to worry about this – you got it installed.

In case you got a old standard trasmitter you can check if the wifi modul is installed:

– remove the crossfire from the jr-adapter and open it up
– flash your crossfire with fw 3.24 and check if you get a wifi network called „TBX_XF_AP_XXXXXXX „


You need to have your Crossfire installed in your radio and powerd up by it – otherwise the wifi modul does not get power.

In case you got ain’t got the wifi modul installed or no longer got the jr-adapter (e.g. x-lite mod) you can get one from different sources:

Note: TBS announced an extra WiFi module for external use with a different form factor. If you got time to wait for it to be available you don’t have to add your Module.


To initiate the wifi modul and start the TBS Cloud you need a few thing:

  1. Hi, my name is Alex, I’m from Russia! could you tell me what to do? as a result of the firmware, wi-fi disappeared on tbs tango2. (v3)

    now stands freedom tx 1.25

    Tango II XF 4.10

    downgrade does not help.

    how to get wi-fi back? only with the help of the programmer?

    and for the fact that there is no wi-fi, I cannot make a connection (bind) to the nano Rx (((

    • hi alex,
      1. the missing wifi module is not related to binding issues. if you got problems there, feel free to send me a mial to kk[at]katze-fpv.de.

      2. for the missing wifi module – i guess the update went wrong. you can get it back to live wiht a ftdi adapter. when you flash the wifi module directly. for the general how to check out my article at the tbs helpdesk for the fusion.
      t2/ crossfire/ tracer works the same way.

      if you can wait a few more days, i’ll update this article for tbs with the correct pins

  2. Hi i was trying to connect to my wifi Crossfire lite module, but network apears for a few seconds and then disapear, also my computer is no able to connect when network is available, i tried to connect with several devices with no luck.

    firmware on lite module is 3,28

    • hi jaidwaj,

      yes this works with the tracer to.
      as the crossfire and the tracer got the same engine underneath, what works with the crossfire also work with tracer.

      just make sure you send mavlink data in to the receiver – the wifi module does not yet support mavlink emulation (as the BT module of the big crossfire tx does).

      the details can be found in the tracer manual under additional inflammations

  3. Hi , when I tried to do this I got this message. Update error : ERROR[10]: Magic byte is wrong ,not 0xE9
    Has any one had this problem and how did they solve it
