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. I'm wondering if either this doesn't have rx/tx funtionality or the pins are just something that's not obvious. Can anyone help?

Hi!
Unfortunately I don't have S3 lite, but It should work OK. Can you provide your config (without passwords and keys)? Did you try to switch TX RX?
