Hello guys,

After a firmware upgrade, using this link "http://forum.cometsystem.cz/doc/firmwar … -5-7-4.zip" the process was successful for almost all devices, but now  I have the following situation:

-    on one device the process failed, immediately after initiating the upgrade process it stuck at the stage "sending firmware" and cannot be terminated without the command ctrl+c, after this command the sensor cannot be accessed anymore but the device still respond to ping request. I tried different ways to recover but with no success: factory reset procedure doesn't work(nothing changed on the device still respond to old IP address), trying with TSensor over the console port and Ethernet with no result, the device cannot be accessed.

-    on other sensors the following error occur, I checked the device and  is enabled and IP address is correct
