Some notes about Victron BLE #2
Description
Hi,
Just want to share my discovery results..
Victron sends Data (and messages) using both ["306b0003-b081-4037-83dc-e59fcc3cdfd0"] and ["306b0004-b081-4037-83dc-e59fcc3cdfd0"]. You'll need to combine notifications to one buffer since sending characteristics can change even middle of the message.
