Still no 5ghz wifi :(

Any idea if the BT5 stack now supports long range mode?

Ah thanks, missed that somehow. The old ones had BT5 support, but somehow got the certification without LR support...

Just checked and seems not available on the usual suspects yet (AliExpress, etc).

Would be fun to experiment on the RISC-V stack.

I was recently looking into using some ESP32s to use on a BLE hardware project I am working on at the moment.

Although I do wonder whether wifi would be a better technology to use sometimes. The only thing I remember seeing is that wifi technology uses much more power.

From TFA it looks like WiFi 6 uses less power, is this true?

Anyone experienced have any suggestions whether BLE or WiFi would be better for streaming serial data from a device onto many platforms? (I currently have a BLE demo working, but working with Bluetooth stacks on mobile and desktop are a royal pain, network requests are very straightforward at this point)

WiFi 6 supports 5ghz

Does the packet processing for WiFi and bluetooth take cycles from the CPU, or is the CPU 100% available to the application code? I read the blurb but it didn't address this question.

For equal target transfer rate and range, I don't think there would be a mode that any WiFi tech beats BLE in terms of using less power.

If power is your concern, have you considered nRF5 devices? Nordic has a proprietary profile for sending serial data over BLE (NUART) but AFAIK, you could only connect to one device at a time (not many).
