# `XMAVLink.Util.ParamRequest`
[🔗](https://github.com/fancydrones/xmavlink/blob/main/lib/mavlink_util/param_request.ex#L1)

Convenience helper for requesting a vehicle's full parameter list.

The helper watches `XMAVLink.Util.CacheManager` state and resends
`PARAM_REQUEST_LIST` while the cached parameter count is not progressing.
Retries are bounded by default; pass `:retries`, `:retry_interval_ms`, or
`:router` in the options to override the defaults.
