I’m trying to reply a signal from hand transmitter barrier gate opener.
Here are the Technical data (no FCC ID, I’m in Europe):
- Hand transmitter Hormann HSP 4 BiSecur
- Frequency 868 MHz
- Intended use: It can be operated with both the BiSecur radio and the fixed code 868 MHz. Other types of application are prohibited.
- Manual: https://www.thegaragedoorcentre.co.uk/userfiles/downloads/Hormann%20HSP4%20Remote%20Controls.pdf
Opener is probably using a fixed code, because it doesn’t have any BiSecur gateway.
Flipper doesn’t decode the signal, so I’ve tried to read a raw signal. I’ve tried all modulation settings, but none of them works when I reply the signal (see attached recordings).

Any idea what to try next? How to find the correct modulation if none of predefined works?
