@kintel Thanks for adding this, looks good. I will test this on Monday (I have a Uno WiFi Rev2 at my desk).
Note: This does not add support for board type and board ID - these will still be "unknown" as today.
I added an issue to address this here: https://github.com/adafruit/Adafruit_IO_Arduino/issues/98
@kintel Compiles OK on my end but I think my pinouts for the ESP32 are incorrect - Could you provide me with two things before I test again:
.ino
and the config.h
file) you used, as a comment below?library.properties
to bump the version (https://github.com/adafruit/Adafruit_IO_Arduino/blob/master/library.properties#L2) from 3.2.2
to 3.2.3
? Then, add and commit that file to this pull request.@brentru Yeah, this probably warrants an example as there are some assumptions being made in the existing examples about how groups of preprocessor symbols always being defined together.

@brentru My above example may be nice to add as a proper example btw. The only trick was to specifically check for the Uni Wifi Rev. 2 as it already have most of the needed defines.
@kintel LGTM, pulling in
Thanks for rapid turnaround!
This PR adds support for float formatting on Arduino UNO Wifi Rev. 2. Since that Arduino variant uses the "megaAVR" core, which has much of the same limitations as regular AVR cores, the
ARDUINO_ARCH_AVR
preprocessor check wasn't sufficient to catch this.This issue was discovered by using said board to post decimal values to Adafruit IO.
Note: This does not add support for board type and board ID - these will still be "unknown" as today.
