Carry the radio's version and model on every telemetry event - #2541
Conversation
They were attached to the connect action alone, so a crash, a hang or a view carried nothing about what the phone was talking to — the values existed on one event per session and nowhere else. They are global attributes now, set where each becomes known rather than at the end of connect: the firmware version with the device metadata, the hardware model with the connected node's info. On a reconnect either can land after the connection is already up. Cleared on disconnect so the next session does not inherit the last radio's details. The connect action also reported nothing on some reconnects, for the same reason: device.firmwareVersion is briefly nil in that window. It now falls back to the version stored at the version check, the way checkIsVersionSupported already does for the same window.

📝 WalkthroughWalkthroughThe PR adds Datadog global radio context for firmware and hardware model values. Accessory manager events set these values during connection and metadata handling, and clear them after disconnection. Connect logging also uses a stored firmware version fallback.

every connection teardown path clears the previous radio context, and remove the
redundant call from disconnect() if necessary. Preserve the existing discovery
and switching-device behavior.

- Around line 322-323: Update the firmware fallback in the connect flow to
associate the cached version with the connected device’s device.id, and only use
it when that stored identity matches device.id. Prevent versionCheck == false
from reusing another radio’s global firmware value.

Review found two holes. The clear ran in disconnect(), which is only the path the user takes. An unexpected link loss, a failed connect and a retry all tear down through closeConnection() without going near it, so the old radio's details stayed attached to whatever happened next. Moved into closeConnection(). The connect action fell back to UserDefaults.firmwareVersion, which holds whichever radio was version checked last. A second radio connecting before its own metadata arrived would have been reported with the first one's version — worse than reporting nothing. It reads that node's own stored metadata now.
Summary
The connected radio's firmware version and hardware model were attached to the
connectaction and nothing else, so a crash, a hang or a view carried no way to tell what the phone was talking to. The values existed on one event per session.They are global attributes now, so they follow everything reported until the radio goes away.
What changed
setRadioContext(_:_:)andclearRadioContext()on the Datadog logger, backed by the SDK's global RUM attributes.connectaction itself reported nothing on some reconnects, becausedevice.firmwareVersionis briefly nil in that window. It falls back to the version stored at the version check, which is whatcheckIsVersionSupportedalready does for the same window and says so in its comment.Testing
Builds clean for the simulator; SwiftLint clean on all four files.
Not verified against live telemetry — that needs a build in the field, and the useful check is that crash and hang events start carrying both values rather than only the connect action.
Noticed while here
UserDefaults.hardwareModelis declared with a default of "Unset" and never written anywhere, so it was not usable as a fallback for the model the way the firmware one was. Left alone here.Summary by CodeRabbit
