Early supporter of z-wave here who hasn't been able to use the devices for a long time due to lack of support in my z-wave controller (wouldn't adopt non recognised devices).

I have a quantity (12) of older ZWave.me devices (Gen1 I think from 2017). I've recently switched controllers and wanted to take advantage of these.

I've configured arduino 1.8.x and installed both the latest and oldest versions of the z-wave.me Zuno tool chain and tried to update the bootloader on multiple devices.

I get two errors, firstly>

Code: Select all

Openning port                            ..............................                            OK
Closing port                             ..............................                            OK
          ERROR: It's not ZUNO G1 connected to port:COM4.

and then after attempting to syncronise>

Code: Select all

Closing port                             ..............................                            OK
Openning port                            ..............................                            OK

Error  0	 Can't sync with Z-Uno bootloader. It doesn't respond!

I find this odd considering board info correctly identifies this device as a Zuno>

Code: Select all

BN: Z-Wave>ME Z-Uno
VID: 0658
PID: 0200
SN: (null)

I get the same error when trying to upload a sketch as well, so currently these are about as useful as a chocolate teapot!!!

I'm guessing that I'm a major version out of date somewhere which is disappointing. Is there anyway I can recover these devices to something workable. I'm not expecting to be able to go all the way up to latest but it would be a shame to throw away £600 worth of electronics which should be perfectly functional for at least a limited use case!

Should probably have noted, currently running on windows

You have downloaded the package for the second generation of Z-Uno, while your are first generation. Please download another package (on the https://z-uno.z-wave.me site you can also switch the documentation to Gen 1 in the top right corner)

@poltos - I got a similar error with both Gen 1 and Gen 2 toolchains

Please provide more logs and information so we can analyse the issue.

I have the same issue of not being able to upload the bootloader. Uploading a sketch does work correctly though. How can I get the software in my z-uno updated to the latest version available?

For board info my board returns:

Code: Select all

BN: Z-Wave>ME Z-Uno
VID: 0x0658
PID: 0x0200
SN: (null)

My arduino environment is

Code: Select all

CLI Version: 0.32.3

In board manager I have 'Z-Uno by Z-WAVE>ME 2.1.8 installed.
The information shown in the output is:

I also tried it using Arduino 1.8.57.0 and there I got the exact same output.
