¿Como podría hacerle para enviar por UDP siendo el ESP8266 un Access Point?

[@geoffpedder]

for anyone else having issues -- udp.write(reply) doesn't work. instead try udp.print(reply)

Thanks for the tip, print should work fine for sending text. What error are you getting when using write? I tested this code recently but forgot if I needed to make any changes, maybe check the most recent code on the blog post: siytek.com/esp8266-udp-send-receive/
