enbeep

enbeep sends short messages as beeps — sixteen pitches a microphone can hear and check. Pick a sender below, then listen here or on a second device. It is an experiment: quiet rooms and matching symbol lengths matter.

A — Send from a MikroTik router

1. In a router terminal, check the beeper: :beep frequency=4000 length=500ms. No sound means no sender on this box.
2. Load the encoder into that terminal — pick one:
   Option 1 — paste (works everywhere): copy the whole script, paste it:

   Show enbeep.rsc

   Loading…

   Copy
   Option 2 — fetch (experimental: needs the router to reach this site; CHR-verified, one 7.16 hardware check still open): paste this one line, no file download:

   loading…

   Copy
   Globals are RAM-only: reload after reboot. (plain file.)
3. Dry-run silently (edit the message, keep the quotes plain):

   $enbeepText "Hello" 200ms 200ms yes

   Copy Expect FRAME and T: lines. Anything else means the load failed — repeat step 2.
4. On the listener, open the Decode tab, pick the same symbol length, press Start Listening, and hold the mic ~0.3 m from the beeper.
5. Back on the router, play it for real:

   $enbeepText "Hello" 200ms 200ms no

   Copy Keep the terminal connected through the frame (~13 s at 200 ms). The MAC/IP announce variant is $enbeepAnnounce "bridge" 0 200ms 200ms no (interface + address row are yours to choose).

B — Send from this speaker

One device's speaker stands in for the router — same v2 tones and checksum. Type a message, play it, and listen on a second device.

Sender and receiver must use the same symbol length (Decode tab). This page also decodes its own playback — only the other device's result proves sound crossed the room.

If it fails

Check the symbol match first, then distance, speaker volume, and room noise. Rejections are data: open Diagnostics → Copy diagnostics report while the attempt is still on screen — the report keeps your last session across one reset. Slow or quiet beeper? Try 400 ms both sides.

Then listen

The beeps need a listener: on this or another system showing this page, open the Decode tab, pick the same symbol length, and press Start Listening before the sender plays.
