Check if your device is connected properly before asking for support.
If your device isn’t connected properly contact your hardware supplier as this is typically a hardware/firmware issue.
We do not provide hardware/firmware support.
thanks for your understanding.
Use the SLI-PRO or the SIM RACE Deluxe or SIM RACE F1 configuration app to see if your firmware is ok
you should have:
AND NOT *BOOTLOADER*
SLI-PRO FIRMWARE ISSUE:
In Devices and Printers window, you should see SLI-PRO Interface and not bootloader
(bootloader usually means that you need to reinstall your firmware ).
