Hi,
Yes, I've also received refunds for purported BMEs.
One way to tell is that the "can" (i.e. the sensor itself) for the BME is almost square (2.5mm) whilst the BMP is more rectangular. But I think they both fit on the same PCB footprint, so the boards are marked with both BMP and BME legends and at least some of the "confusion" is genuine mistakes. Often the descriptions are "misleading" for the same reason as if I were doing a cut-and-paste in Chinese.
My advice (unless you want to receive a "free" BMP280 ) is to avoid the "6-pin" modules (daughter boards), and of course any that are priced below about 2 UKPounds/Euros/Dollars. I recommend the (rather smaller) "4-pin" modules, often sold as "5 volt" compatible, which have a pair of buffer (level changer) FETs on the back of the board. Sometimes the sellers don't show the rear view, but the style usually can be determined from the top view. When I was looking, the lowest price from China was almost $4, or more than £10 for the "branded" versions from Europe.
Cheers, Alan.
