LED flash at active MODBUS Connection

[ovhelemann]

Hi,
I just implemented a Modbus communication and since my Charger LED flash with white/blue color each minute, even if I have my LED in power saving mode. I noticed, when Modbus is shut of, the LED keep turning of.

I suppose the LED flash, when receiving write commands from my modbus server. Even though if I do not change any register values. But my software uses "minimum write points" functions to keep the values up to date.

Did anybody notice this as well? Is there a way to switch the flashing off. I think otherwise my neighbour is going to unmount my charger :)

Thanks in advance
