TestCode_Infos_Espruino.js

/*
R: the following was working with the red FTDI adaptor providing power & the Pico only having the following in the right pane of the Espruino IDE

```
Serial1.setup(115200, { rx: B7, tx : B6 });

var at = require("AT").connect(Serial1);
at.debug();
// R: we could connect the NET pin & check whether it's pulsating, HIGH, or LOW to know if we have to reboot the module
digitalWrite(B4, 0); // power off SIM800L module
setTimeout(function(){
  digitalWrite(B4, 1);  // power on SIM800L module
}, 1000);
```

To have an interactive console that is somewhat like using 'screen', we can use the following
```
Serial1.on('data', function(d) { USB.write(d); });
at.write("AT\r\n"); // same as typing 'AT' + Enter in 'screen'
```

The following was also quite useful to see some faulty output on the Serial
```
/*
Serial2.setup(115200, { rx: A3, tx : A2 });
Serial2.on('data', function(d) { USB.write(d); }); // log stuff received from SIM800L to web ide console
USB.on('data', function(d) { Serial1.write(d); });
*/

/*
Serial1.setup(115200, { rx: B7, tx : B6 });
Serial1.on('data', function(d) { USB.write(d); }); // log stuff received from SIM800L to web ide console
USB.on('data', function(d) { Serial2.write(d); });
*/
```
