Phoenix IP43 charger - is there a ve.direct HEX protocol spec document

Hi,

I am receiving BLE advertising packets from a Phoenix IP43 charger, parsing the data and emulating a ve.direct connection using a microcontroller. There are a bunch of HEX commands that I can not find in any documentation coming from my Venus Pi device. Is there protocol documentation available for this line of products like there is for other products?

Thanks
