rUv ce171696b2 fix: rate-limit CSI sends and add ENOMEM backoff to prevent crash (#132) ... The CSI callback fires for every WiFi frame in promiscuous mode (100-500+ fps). Each call invoked sendto() synchronously, exhausting lwIP packet buffers (errno 12 = ENOMEM). The rapid-fire failures cascaded into a LoadProhibited guru meditation crash. Two fixes: 1. csi_collector.c: Rate-limit UDP sends to 50 Hz (20ms interval). CSI frames arriving between sends are dropped — the sensing pipeline only needs 20-50 Hz. 2. stream_sender.c: When sendto fails with ENOMEM, suppress further sends for 100ms to let lwIP reclaim buffers. Logs the backoff event and resumes automatically. Closes #127		2026-03-03 16:00:40 -05:00
