It looks like this device does send its name (iTag) and some manufacturer specific data, but we need to figure out what it means

0eff0501ffff10a4053e6602010300

0e = length
ff = manufacturer specific data
0501 = UUID
ffff10a4053e6602010300 = data.

I will need a longer log with a number of log lines with this long BLE advertisement for multiple messages, to see what changes
