ble write

Writes each message's payload to a characteristic of another Bluetooth LE device.

Properties

• BLE peer — the device to write to. Required.
• service UUID / characteristic UUID — the characteristic to write: 16-bit or 128-bit. Required.
• encoding — how payload becomes bytes: the same choices as ble read. Default bytes. A number must fit.
• wait for the peer's response — default on: the device confirms each write, and a write it refuses is reported. Off: write without response, which is faster; the characteristic must allow it.

Wiring

Input — payload is the value to write.

This node has no output.

Behavior

Nothing is queued: a message that arrives while the peer isn't connected is reported and dropped, so a stale value is never written after a reconnect.

Errors

Not connected, a write the device refuses or doesn't confirm within 5 seconds, or a payload that doesn't fit the encoding is reported on the console.
