  -setup raspberry pi with Jessie

  -installed mosquitto on raspberry pi

  wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
  
  sudo apt-key add mosquitto-repo.gpg.key
  
  rm mosquitto-repo.gpg.key
  
  cd /etc/apt/sources.list.d/
  
  sudo wget http://repo.mosquitto.org/debian/mosquitto-jessie.list
  
  sudo apt-get update
  
  sudo apt-get install mosquitto mosquitto-clients

  -setup esp8266 using an FTDI serial USB adapter set to 3.3V:

  -Use a 3.3V regulator or a 3.3V supply for the ESP itself, not from USB (it can sink a lot of current)

  -Vcc => 3.3V

  -EN => Vcc

  -GPIO15 => GND

  -GPIO2 => Vcc via resistor (I used 10k)

  -GPIO0 => GND for flashing, then moved to Vcc for runtime

  -Rx => FTDI Tx

  -Tx => FTDI Rx

  -FTDI GND => GND

  -use esptool to flash NodeMCU float (dht,file,gpio,mqtt,net,node,tmr,uart,wifi)

  esptool.py --port /dev/ttyUSB0 --baud 57600 write_flash 0x00000 firmware.bin

  -move GPIO0 to Vcc

  screen /dev/ttyUSB0 9600

  wifi.setmode(wifi.STATION)
  wifi.sta.config("ESSID","password")
  

  print(wifi.sta.getip())

  -setup raspberry pi 3 as wifi access point (no NAT):

  -adafruit article below

  -changed hostname

  -isc-dhcp-server

  -hostapd (device is nl80211)

  sudo apt-get update
  sudo apt-get install hostapd isc-dhcp-server

  /etc/dhcp/dhcpd.conf:

  #
  # Sample configuration file for ISC dhcpd for Debian

  # The ddns-updates-style parameter controls whether or not the server will

  # Fixed IP addresses can also be specified for hosts.   These addresses
  # should not also be listed as being available for dynamic assignment.
  # Hosts for which fixed IP addresses have been specified can boot using
  # BOOTP or DHCP.   Hosts for which no fixed address is specified can only
  # be booted with DHCP, unless there is an address range on the subnet
  # to which a BOOTP client is connected which has the dynamic-bootp flag
  # set.
