Connecting to one of available WIFI's

Listing the WiFI APs

Using either a PICO or an Espruino Original Board connected via the serial port to and ESP8266.

The code:

//GetAPs.js  11Jan2018
// ESP8266 connected via serial port to PICO or Espruino Board

//espruino board with ESP8266
//PICO  with ESP8266

//var Hardware=0; //Espruino board
var Hardware =1; //PICO

var Serial;

//setup serial port
if(Hardware===1)Serial=Serial2;
if(Hardware===0)Serial=Serial4;

if(Hardware===1){
 digitalWrite(B9,1); // enable on Pico Shim V2
 Serial.setup(115200, { rx: A3, tx : A2 }); //Pico
}
if(Hardware===0)Serial.setup(115200, { rx: C11, tx : C10 }); 
//espruino board

var cmd="";
Serial.on('data', function (data) { 
//  console.log(data);
  cmd+=data;
  var idx = cmd.indexOf("\r");
  while (idx>=0) { 
    var line = cmd.substr(0,idx);
    cmd = cmd.substr(idx+1);
    print(line);
    idx = cmd.indexOf("\r");
  }
});

function sendAT(){
  Serial.print("AT");
}//end sendAT


sendAT();
setTimeout(function () {
  console.log("Hello World1");
  Serial.write("+++");
setTimeout(function () {
  console.log("Hello World2");
  Serial.write("AT+CWLAP\r\n");
}, 5000);
}, 5000);
