ble uart out

Sends text to the devices connected over Bluetooth LE, through the Nordic UART Service.

Properties

  • end with a newline — add \n after each payload. Default on.
  • BLE — the flow's BLE config.

Wiring

Input — payload as text. Bytes are sent as they are; anything else is sent as str(payload).

This node has no output.

Behavior

The text goes to every connected device, split into pieces that fit each connection: 20 bytes until the device agrees a larger MTU. With no device connected, nothing is sent and nothing is kept.

Errors

A board without the ble nodes stops the deploy. Anyone in range can connect and read what's sent: there's no pairing.
