An ESP8266 can either associate as a station to a phone acting as an
access point, or can act as an access point with the phone a station.

However, a phone operating system will usually assume presence of DNS
server, and may not be happy without it.  Especially important if you
wish to use HTTP.

A DNS liar can be used.  I've tested this with laptops and phones:

You can avoid HTTP of course, and this may be simpler.

You will need two pins for serial on your PIC, and attach them to the
ESP8266.
