Hello, I have a question about the STWBC. After the charge is completed the EPT CHARGE COMPLETE will show up in the protocol screen in the GUI. Once the device is charged the charger will not come back into ping status.

After a the device is charged the stwbc needs a power cycle before the it will come back in ping status. Is it possible to set the charger always into ping status after a charge is completed with the parameters?Thanks in advance, Marco
