TELTONIKA FMC234 unable to connect or upgrade firmware (Windows 11 – USB & Bluetooth)

Telematics Issue
1

Hi,

I’m having issues with my Teltonika FMC234 device.

I am using Windows 11 and I am unable to connect to the device using both:

  • USB connection

  • Bluetooth connection

Details:

  • Device: FMC234

  • OS: Windows 11

  • Configurator: (latest FMB series version)

  • Connection type tested: USB and Bluetooth

  • Drivers: Installed (COM port drivers)

Issues:

  • Device is not detected in Configurator via USB

  • Bluetooth connection does not work either

  • Unable to read device data

  • Unable to upgrade firmware

What I already tried:

  • Installed latest drivers

  • Tried different USB cables

  • Tried different USB ports

  • Restarted PC

  • Reinstalled Configurator

  • Checked Bluetooth pairing

Still no success.

Has anyone experienced this issue or knows what could be causing it?

Thanks in advance.

I have exactly the same issue as you. Device comes up both in com and Bluetooth but the configurator says that is not supported. My device has the same firmware as yours. My guess is that we need a special version of the configurator, but I cannot find any apart from the two linked.
