Identify which firmware you are running by opening a notepad on the host device and pressing N+S 0R00 on the Twiddler.
All Twiddlers come factory installed with a firmware version ending in “b”, for “Base”, e.g. 0.07b.
All in-field upgrade firmware is designated with a “u”, for “Upgrade”, suffix instead, e.g. 0.09u.
Only changes in the numbers of a firmware name indicate differences in the firmware, so 0.09b and 0.09u are functionally the same.
Upgrading from 0.07 to 0.09 will show a firmware version of 0.09u afterwards to indicate that you have upgraded from 0.07b.
