Could you say a little more about how you plan to use BTLE and which units you’re using? I set one of these up last month and it’s generally great, but yeah wifi is a hog. It never occurred to me that something with BTLE would make such a difference.

It’s a great form factor though, isn’t it? Kicked off a bit of an e-ink / esp32 boom for me. I just bought 4 integrated 4-inch displays to complement this 7.5.
