Arduino UNO Q Call

Summary

Call a method on an Arduino UNO Q microcontroller unit (MCU) via an established bridge connection, optionally passing typed parameters and handling idempotent retries.

Inputs

  • Method (required) — Name of the MCU method to call, which must match a Bridge.provide() name in the Arduino sketch.
  • Specify Parameters (required) — Determines how parameters are provided: none, as typed fields (ordered list), or as a raw JSON array.
  • Parameters — If specifying parameters as fields, an ordered list of typed values (string, number, boolean, JSON) passed positionally to the MCU method.
  • Parameters (JSON) — If specifying parameters as JSON, provide a raw JSON array passed positionally to the MCU method.
  • Idempotent — Indicates whether the method call is idempotent; when true, the node automatically retries calls if the socket disconnects mid-call within the timeout.
  • Options — Additional call options including timeout in milliseconds and deprecated socket path (only used if no credential is assigned).

Output shape

a single response object containing the result returned by the MCU method call

The node waits for the MCU response, respecting the timeout setting. If idempotent is true, it transparently retries on connection errors. Parameters must align positionally with the MCU method signature.
