Gap Report from RX Operator

Transmission

Slice size (bytes) Slide interval (ms)

Advanced

QR error correction Repeat Setup Slide every %

A Setup Slide always opens each Rotation; repeating helps late joiners (A.4).

Interval applies immediately; other changes apply when the next Rotation starts.

How to run a transfer

Share this window (not the whole screen) on the video call; keep it as large as possible, avoid overlays.
Start the Rotation. The RX Operator watches with the RX Client.
When a Rotation or two has passed, ask the RX Operator for a Gap Report over chat, paste it here, Apply.
A report ending in - means nothing is missing: you can stop.
If Symbols fail to decode on the far side: increase Slice interval or reduce Slice size.

RX reports nothing missing — transfer complete. Transmission stopped.
