Updating OSTC Sport to 1.40

[Sp3xX]

Hi all,

hope somebody can help!

Trying to Update my OSTC Sport (Red Buttons) to 10.40 like I always did in the past but getting this error:

OSTCSport selected.
Upgrading firmware...
Loading firmware.
Erasing Firmware.
Uploading firmware.
Verify firmware.
< block timeout (missing 4096 bytes)
Error: < block timeout (missing 4096 bytes)

What am I doing wrong?

3,6V Battery? The OSTC Sport with non-BLE Bluetooth (Red button "Sport" ) have sometimes trouble with a 1,5V Battery and Bluetooth.

regards,
Matthias
