Hello @ayone0518 ,

the easiest way is to use the official backup tool as described on our knowledge base: https://kb.unipi.technology/en:hw:01-axon:backup2usb

@niklas EnOcean is not directly supporter right now, altought its support will get higher if things goes ok. How do you want to handle the communication?

Anyway regarding the issue you are having, plugging a device into a USB cannot cause such error. There is something wrong with the project definition. If you want, share the whole project folder as a zip archive so we can take a look at it.

@cvrcejir :) please try to install evok on clean raspbian and let us know. what distribution did you use? maybe the installation log would tell us more..

@cvrcejir Do the RUN leds blink sometimes or not at all? Has Evok been installed on clean Raspbian?

@raubucs Can you share the whole project? Have you tried all of the RS485 lines?

@heikkim Hello, to enable wifi you should enable the interface in /boot/boot.cmd by commenting the followin lines (add a # at the beginning)

fdt set /soc/mmc@01c10000/bcrmf@1 status "disabled"
fdt set /soc/mmc@01c10000 status "disabled"

Then run mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr and reboot.

Does it work?

@jcmschoot what UART device? Do you have some RS485 usb converter?

@mmcreativ Unfortunately the source project is not stored on the PLC so there is no way to recover it.

@roberts_lando Evok uses the Modbus TCP interface to interact with the IOs, disabling it will cause that evok wont work.

You can disable it by calling "systemctl stop unipitcp" and "systemctl disable unipitcp".

@leif-edh That is doable but you would need to setup WiFi access point on one of those M205 (find a tutorial for hostapd), and enable bridging (available in bridge-utils package).

If you won't use static IP addresses, you would have to also setup a DHCP server on the WLAN and eth, br interfaces.

This tutorial might help you a bit: https://www.cyberciti.biz/faq/debian-ubuntu-linux-setting-wireless-access-point/

Another option is to put a router AP in the middle of it all.

Also, note that the internal wifi antenna does not have much gain and is inside an aluminum box so the range is limited...
