LYWSD02 Support Request (Crashed hard trying to use it as is) #8368
Description
I figured I'd give this a shot as at least from the outside the LYWSD02 seems awfully similar. It displays the same data and it seems to share the same UUID https://github.com/adafruit/Adafruit_CircuitPython_BLE_LYWSD03MMC/blob/8bc79c6fcb72699c159129e8a1b0d27a5eaec9f7/adafruit_ble_lywsd03mmc.py#L66
So I put adafruit_ble_lywsd03mmc.py in my libs directory and copied over the content from ble_lywsd03mmc_simpletest.py to my main.py.
The only thing I changed was change line 19

I'm guessing this is not actually due to a shortage of RAM although I don't have a board with more RAM to test it on.
I'm using a BPI-Leaf-S3 which is an ESP32-S3 based board with this memory configuration:
| Type | Amount |
|---|---|
| Internal SRAM | 512 KB |
| Onboard FLASH ROM | 8MB |
| In-packge PSRAM | 2MB |
If it's of any help to add support there seems to be a PyPi library for the LYWSD02 over here:
https://github.com/h4/lywsd02
Adafruit actually seems to stock this particular Clock/thermometer/hygrometer so support for it would be neat.
I'm very new to circuitpython but let me know if you need more info :)
