If you are using NOT using official firmware, be sure your settings_user file matches the file your firmware uses (or you may lose some customizations). Perhaps download the existing setting file from your Flipper Zero and append the data to the end of the file. Below is the original AM650 data (Register 0x10 [MDMCFG4] has value 0x17 = 650kHz): - Custom_preset_name: AM_650_data - Custom_preset_module: CC1101 - Custom_preset_data: 02 0D 03 07 08 32 0B 06 14 00 13 00 12 30 11 32 10 17 18 18 19 18 1D 91 1C 00 1B 07 20 FB 22 11 21 B6 00 00 00 C0 00 00 00 00 00 00
Thanks. I was planning on covering custom PATABLE as well (the last 8 bytes of the custom data), but I decided it needs its own video. Oh well, it gives people something to look forward to for next Saturday. 😃
I watched this and the previous video on adding frequencies and now I would like to apply this to a problem. I have a door sensor which rtl_433 readily decodes as a Honeywell Security sensor. (It is handled by the honeywell.c module in rtl_433). I have tried to record this sensor using READ RAW at 345M and AM(650). Replay does not work. I also tried recording as an .ook file using RTL_433 and converting to .sub and when played by the Flipper has no effect. honeywell.c says: .modulation = OOK_PULSE_MANCHESTER_ZEROBIT. Can you offer advice on how to get a replay to work?
I'm still learning, but it seems like each time that particular device should send the same code (its not rolling)? I would think with Read RAW at 345MHz it should have worked (but depending on other signals, you may need to adjust the RSSI Threshold). Since it is using Manchester Zero Bit with short_width=156, I would think you could save the raw file and you should see all of the values be roughly (117 to 195) or (234 to 390) and I would expect about 60 positive and 60 negative numbers (12 bit preamble+6 bytes data) all within those ranges? It's highly likely that 345MHz isn't a civilian band in your region, so perhaps that is the issue? What does rtl_433 detect when you use the Flipper to transmit (maybe even try as an OOK file & look at the pulse lengths)? Feel free to reach out to me on Discord at codeallnight#1337 if you have additional questions.
I just released ua-cam.com/video/VxMDdYuRITE/v-deo.html on data rate, which will allow the Flipper to record and transmit the signal which the rtl_433 will decode as an identical signal. For some reason, the signal from the Flipper still doesn't work on the actually receiving device!!! At this point, I'm not sure what are the differences between the Flipper Zero TX and the actual sensor. Perhaps the TX frequency is slightly too far off (I've seen the FZ be off by up to 200kHz)?
Thanks! If you are looking for a FSK with deviation around 11.6KHz, you can set Register 15 to 0x26 = 11.108KHz or 0x27=11.902KHz FM11-1 would have a custom setting like: 02 0D 0B 06 08 32 07 04 14 00 13 02 12 04 11 83 10 67 15 26 18 18 19 16 1D 91 1C 00 1B 07 20 FB 22 10 21 56 00 00 C0 00 00 00 00 00 00 00 github.com/jamisonderek/flipper-zero-tutorials/wiki/Sub-GHz#deviation-1 Here is my discord server, which is the easiest way to have a dialog... discord.com/invite/NsjCvqwPAd

Fantastic Video! I just got a Flipper and your videos are exactly what I’m looking for. Thanks!
Glad it was helpful! I have a playlist of subghz videos -- ua-cam.com/play/PLM1cyTMe-PYKeMm52J8Y_4SKqdm6Utl__.html
Nicely done!

Good stuff. Aside from being a good resource for the flipper, the register information is also very helpful for the Yardstick One which uses a cc1111
I haven't bought a Yardstick One yet. I ended up getting a few other toys at defcon and went over my budget (just like every
year).
Amazing
The best
Love it!
Thank you!
Let me know if it helps and what rate you end up using. (Internal vs External seems to have different speed requirements).

amazing explanation is it possible to achieve FSK 11.6KHz modulation? based on your table 58 is the lowest one?
Thanks!

FM11-1 would have a custom setting like:
