Creates instance. You probably would rather use puck to create.
Adds event listener.
Events
Event name
Event handler
Sends some code to be executed on the Espruino. The result is packaged into JSON and sent back to your code. An exception is thrown if code can't be executed for some reason.
const sum = await e.eval(`2+2`);
It will wait for a period of time for a well-formed response from the
Espruino. This might not happen if there is a connection problem
or a syntax error in the code being evaled. In cases like the latter,
it will take up to timeoutMs (default 5 seconds) before we give up
waiting for a correct response and throw an error.
Tweaking of the timeout may be required if eval() is giving up too quickly
or too slowly. A default timeout can be given when creating the class.
Options:
timeoutMs: Timeout for execution. 5 seconds by default
assumeExclusive If true, eval assumes all replies from controller are in response to eval. True by default
debug: If true, execution is traced via warn callback
Code to run on the Espruino.
Options
Optionalwarn: (message: string) => voidFunction to pass warning/trace messages to. If undefined, this.warn is used, printing to console.
ProtectedfireFire event
ProtectedlogRemove event listener
ProtectedverboseProtectedwarnWrites a script to Espruino.
It will first send a CTRL+C to cancel any previous input, reset() to clear the board,
and then the provided code followed by a new line.
Use eval instead to execute remote code and get the result back.
// Eg from https://www.espruino.com/Web+Bluetooth
writeScript(`
setInterval(() => Bluetooth.println(E.getTemperature()), 1000);
NRF.on('disconnect',()=>reset());
`);
Code to send. A new line is added automatically.
An Espruino BLE-connection
See online demos
Use the
puckfunction to initialise and connect to a Puck.js. It must be called in a UI event handler for browser security reasons.To connect to a particular device:
Listen for events:
Write to the device (note the \n for a new line at the end of the string). This will execute the code on the Espruino.
Run some code and return result:
