  • 330xi won’t connect

    Was working on a page boiler today and really needed this app to work. It won’t connect to the analyzer. Both had Bluetooth on but it wouldn’t find any devices.
  • Compatibility with T300

    Are there plans to make this app compatible with the T300. It would make work so much easier.
  • Won’t wok

    I cannot get app to see 330 analyzer. Useless.

    Developer Response

    Please make sure that yo have the BT low energy installed in your device. Please go to device information. Next to BT should stand "LE" if this is not written, then you don´t have LE module installed. A upgrade of that BT module is not possible. Your testo team!
  • Doesn’t work with 320 LX

    I just bought a brand new 320 LX with Bluetooth and it won’t connect with this app?? Was told it was updated. Still can’t connect
  • Works well

    Had my 330-2LL fitted with Bluetooth mainly as I wanted a Bluetooth printer
    It is a useful upgrade for today’s tec.
  • Will not connect to latest IOS devices on testo 300

    I tried this app on iPhone XS and two iPads... would not
    connect to any of them.
  • Horrible APP

    Does not connect to the 320... Why make the App If you wont even correct such a simple problem?
  • Garbage

    I just spent $1,300 on a new 320 lx kit and it won’t connect to my iPhone. So if I want Bluetooth I have to go get another phone line?
  • Doesn’t connect

    Bought a brand new 320 LX looking forward to using this app just to find out this app won’t connect to it. Hope they fix this, as it was a selling point.
  • Soon

    Would like to see app use for testing 350. Don’t use a 330 only 350 so this app does not help me
