obniz to be used
This is a callback function used when an external device gets connected or disconnected.
await obniz.ble.initWait();
obniz.ble.onUpdatePhy = ((txPhy, rxPhy) => {
console.log("txPhy "+txPhy+" rxPhy "+rxPhy);
});Rsponse waiting timeout in milliseconds
Initialized status.
// Javascript Example
obniz.ble.isInitialized; // => false
await obniz.ble.initWait();
obniz.ble.isInitialized; // => trueConnect to peripheral without scanning. Returns a peripheral instance, but the advertisement information such as localName is null because it has not been scanned.
// Javascript Example
await obniz.ble.initWait();
var peripheral = obniz.ble.directConnect("e4b9efb29218","random");
peripheral.onconnect = ()=>{
console.log("connected");
}peripheral device address
"random" or "public"
Connect to peripheral without scanning, and wait to finish connecting.
It throws when connection establish failed. Returns a peripheral instance, but the advertisement information such as localName is null because it has not been scanned.
// Javascript Example
await obniz.ble.initWait();
try {
var peripheral = await obniz.ble.directConnectWait("e4b9efb29218","random");
console.log("connected");
} catch(e) {
console.log("can't connect");
}peripheral device address
"random" or "public"
Calls each of the listeners registered for a given event.
Return an array listing the events for which the emitter has registered listeners.
Return connected peripherals.
// Javascript Example
await obniz.ble.initWait();
let target = {
localName: "Blank"
};
var peripheral = await obniz.ble.scan.startOneWait(target);
if(peripheral) {
try {
await peripheral.connectWait();
} catch(e) {
console.error(e);
}
}
console.log(obniz.ble.getConnectedPeripherals());connected peripherals
Initialize BLE module. You need call this first everything before. This throws if device is not supported device.
esp32 C3 or esp32 S3 Put true in the argument when not using the BLE5.0 extended advertise
// Javascript Example
await obniz.ble.initWait();Return the number of listeners listening to a given event.
Return the listeners registered for a given event.
Add a listener for a given event.
Add a one-time listener for a given event.
Remove all listeners, or those of the specified event.
Remove the listeners of a given event.
Reset Target Device and current SDK status without rebooting. If error occured while reset, then target device will reboot.
// Javascript Example
await obniz.ble.resetWait();ESP32 C3 or ESP32 S3 only
Sets the PHY to use by default
// Javascript Example
await obniz.ble.setDefaultPhyWait(false,false,true);//coded onlyGenerated using TypeDoc
Use a obniz device as a BLE device. Peripheral and Central mode are supported
