This is a long and boring one, so here's the short version: New T3
firmware is out and you should probably update. T3-301 and T3-mini
users, read below if you have problems.
I've just posted a new firmware build for the Tracker3. This one has
the new changes for the T3-mini GPIO support and TX/RX inversion options
- a version with these changes has already been shipping with the mini
boards. A bug with incorrect Base91 decoded positions has also been
A user pointed out that their T3 was resetting whenever it would report
a temperature between 0 and -1 C. This sounds like it would be an easy
fix, but it turned out to be related to the placement of the persistent
hardware configuration byte in flash memory. Somehow it wound up
sharing space with a math routine.
I've relocated it, but T3-mini users may have to re-patch the byte if
they've made changes. For T3-301s, it should automatically detect the
change and patch it.
If, however, your T3-301 should stop responding to SETFREQ and SETPOWER
commands, use the command PATCH 005FFF0120 and then reset. It would
also be a good idea at that point to reload the firmware a second time.
As usual, you can use the 'web' button in otwincfg to update the
firmware. I'll update the website tonight.
