What the advantages of victron_ble_connect component ?

[That-Dude]

Hi

I have a smartshunt using the regular bluetooth connection at the top of you repo, I saw at the bottom of the page I can enable the victron_ble_connect component, what's the advantage of this? Is it worth my swapping.

Thanks
Dan

Hi,
The victron_ble_connect component is the old and initially only way to read data from victron devices. They released the new which is much better.
victron_ble_connect is using Bluetooth connections and is only available for smart shunt.
victron_ble is using Bluetooth announcement protocol and available for most victron devices.

TLDR keep using victron_ble.

OK I've set it up using the instructions but I'm getting an authentication error. Any ideas what I'm doing wrong?

The ESP device yaml is exactly copied from your page.
