Every device with Mervis OS 2.3.0 and newer requires a license.
If the device is not licensed, it will run in demo mode. The demo mode does not limit the functionality, but the program will run only for 20 minutes. After that time, the program will stop running and RUN LEDs will start blinking in a 2-second interval (on/off).
Make sure to Update Runtime at first and then license the device.
Mervis OS are versioned the same way as Mervis IDE releases. Eg. Mervis OS 2.3.0.x will work with IDE 2.3.0 but might not work with IDE 2.2.0. Mervis IDE 2.3.0 requires Mervis OS 2.2.0.x at least, but also requires update of the Mervis RT. Compatibility with Mervis OS older than 2.2.0 is not guaranteed.
SSH is disabled on these OS images by default for security reasons.
If connection to the device via SSH is required, it can be enabled either in service mode, or by uploading configuration of Mervis RT.
The default SSH credentials are: user unipi and password unipi.technology.
After finishing work, it is necessary to turn off or secure SSH.
