Can't send or receive anything with m5stack atom s3 lite

[bdog720]

I had this working on a generic esp32 but I bought and m5stack atom s3 lite for it's small form factor so I could fit it in the AC unit. I've got the m5stack to power on but I can't send or receive anything. I'm attempting to use the 4 pin which states g2 and g1. I've tried gpio1 and gpio2 but nothing. I can't seem to find any reliable information on which gpio ports these use. Can anyone help?

I have more details here on the home assistant forum https://community.home-assistant.io/t/esphome-m5stack-atom-s3-lite-controlling-air-conditioner/809609
