Looking for non-ESP WiFi microcontroller

by blnkjns on Sun Mar 28, 2021 2:54 pm

I'm looking for a microcontroller with WiFI, but not with an Espressif chipset as it is too slow (compiling). Wishlist:
Programmable in Arduino IDE
Wifi B/G/N with WPA2 PSK or even Enterprise compatibility
M4 or better design
Bluetooth is a welcome addition, BLE compatible, preferably 5.0 or better.
Does anything like this exist?

Would it help if the ESP32 were a co-processor? We do have a few options in that category.

; Metro M4 Express AirLift Lite

; AirLift FeatherWing

If you bluetooth was important you could mix in the above AirLift FeatherWing with a Feather nRF52 Express.

Not as coprocessor either please, somehow I don't trust the chip, but I do appreciate how Adafruit does simplify working with it.
Can you guarantee the ESP32s you use don't run an RTOS?

You can read over the issues at the nina-fw repositories and decide for yourself how you feel about it's stability. I would not call the NINA-FW a RTOS.
