I’m confused

Well, the title was meant as some sort of joke (sorry for confusion).
I found that board today and i wanted to share with community as curiosity.
With this board you could add ANT+, threads, zig-bee or BLE5 support to esp32 projects. Of course there is esp32 S3 on horizon with BLE5 support, but other comm protocols may be interesting too.
For example wifi to zig-bee or threads gateway.

I thought it might be a joke. I saw a sort of a Frankenstein board.
But on the internet it’s hard to tell a joke. I made sure it was not April 1.
A lot of functional redundancy. I missed the zig-bee gateway application.
I’ll stick with the ESP32-C3.

Recently I had found this official news on espressif website https://www.espressif.com/en/news/BLE_ ... tification. So it seems that ESP32 is shipped as a BLE 5.0 device. Am I misinterpreting the article?

I love esp32 chips, all models, but i will never forgive espressif that BLE5 certification.
I am not bluetooth expert, but i found there is tricky part about BLE5. Most or all new features are optional. Even 2M PHY and coded PHY are optional. I dont know what is bluetooth certification procedure, but i think espressif passed it only because esp32 is supporting BLE mesh, but i may be wrong of course.
Me and probably many more people using esp32 is happy that C3 and never chips are truly BLE5 capable, even if BLE5 is not that popular in real world devices yet.
I cant wait to get C3 rev 3 with working USB to make USB to BLE adapter for keyboard or mouse or even better to get S3 in my hands. Lets hope we can get them sooner than later.

Just to correct you: USB on the C3 does not have the capability of being reprogrammed into e.g. a HID device. It's purely a programming/debugging peripheral. Sorry, guess you'll need to wait for the S3.

Thanks for info. Ive been told that C3 in rev 2 has broken JTAG and USB host/device and should be fixed in rev 3, but like you said, we will have to wait S3 then.

Many thanks for replying. So if esp32 didn't gain 2M PHY and coded PHY, where is the improvement? Is it just marketing?
