Hey, @allObjects thanks for your response.
Since the devices were quite cheap and on the market for a while I guess it's all old-fashioned BLE 4.
My guess was also that a connection actually might have been avoided by the creators since it means complexity and drawing more battery power.
But my question is this:
Does the quoted advertisement data contain everything the device has to tell us?
Where is the device name that my LightBlue BLE sniffer app shows?
How can I obtain any data from the advertised service and its characteristics when I cannot connect to the device?
PS: I just found the same item on aliexpress and they explicitly say it's BLE 4 - look: https://www.aliexpress.com/item/33041131063.html
