firmware with WIFI AND bluetooth dual mode

[Jp]

Hello

where and what is the best firmware version number including WIFI and dual mode of bluetooth at the SAME time ?
Any weblink and source under Arduino too is welcome.

At the same time, wondering for low power, and uSD card speed/read/write ( 4 bit SDIO mode ?) to store information very quickly for high speed from few SPI devices (or I2C)...

Keep going on the nice and good M5 stack device...
Best Regards

I would be interested in this too. Especially for BT, not BLE.
