How to upgrade firmware version 1.81 to 3.13? I have downloaded the latest firmware version and also installed OSTC Companion v1.2. At first the companion didn't let me choose the *.hex file, but then I searched in the source code and found out that the file must be named *_firmware.hex. After renaming the file the Companion app reported "Error: Bad hex address". I'm using Mac OX.

Should I upgrade to v1.90 and then to 3.13? Where can I get the v1.90?

Hi,

Then you need to install the hwOS firmware: read.php?6,16526

Latest version is 2.07

hwOS on OSTC 2C ?

Hi,

As with most posts here in the forum, we get the same questions via mail, too (Which is really unnecessary btw.).

So I knew that the user has a "OSTC 2" (With Bluetooth and Wireless charging). And this device will not work with the 3.13 for the Mk.2, 2N and 2C (And luckily does not allow installation of this HEX file...)

regards,
Matthias
