Hi there,
NO . on both Items… Seems they forgot the part about entering BL mode?
Terrible device. NOT like the REAL XIAO IMO… a Posser with all the right buzz words but NO BEEF…
Sorry to break the bad news to you… We are anxiously awaiting a solution from the product manager and engineer for this device. I would have ascertained the information so vital to use of this device prior to EVER releasing it to my Customers…
But that’s just ME!
As you were
