2 years ago Hello
In order to see the signal details, could you please record the signal timing and show it? For example using the library RF433snif, https://github.com/sebmillet/rf433snif This'll help understand what the coding is made of, and whether or not RF433recv could decode it.
Regards, Sébastien

2 years ago Hi, I will do as requested, but I will not be able to upload the results until the end of next week. Thank you for your support, Andreas

Given signal timings, RF433any cannot interpret it: it is made of a unique duration followed by a "short or long" signal. RF433any can only interpret "short then long" versus "long then short". The good news is, RF433recv should be able to decode such a signal.
You may try the below decoder:
[...] // Depends on schema...
[...] RF_manager rf(PIN_RFINPUT); [...] void callback(const BitVector *recorded) { // Implement instructions here to execute when code is received... } [...] rf.register_Receiver(RFMOD_TRIBIT, 8550, 0, 0, 0, 500, 500, 1900, 3800, 500, 8550, 37, callback, 1000); [...]
Hope it'll work for you.

2 years ago Hello Sébastien,
I tried what you suggested, but unfortunately it did not work. Thank you very much for your support. I will try a different approach now.
Kind regards, Andreas

2 years ago Hello
I finally could compile and test my code and the correct reception constructor is actually a bit different from what I sent in the first place. Here we go:
// ========================================
...
... RF_manager rf(PIN_RFINPUT); ... void callback_anycode(const BitVector *recorded) { // Write code here }
rf.register_Receiver( RFMOD_TRIBIT_INVERTED, // mod 8550, // initseq 0, // lo_prefix 0, // hi_prefix 500, // first_lo_ign 500, // lo_short 500, // lo_long 1900, // hi_short 3800, // hi_long 0, // lo_last 8550, // sep 37, // nb_bits callback_anycode, // callback 1000 // delay between two calls to callback ); // ========================================
I tested it in real conditions, with a TX emitting the code timings you indicated in a previous post, and it works.

Hi,
when I run RF433any 01_main.ino, all I receive is this:
I am trying to receive the signal of several temperature and humidity sensors I have around the house. On a Raspberry PI I can receive the signal by using rtl_433 and protocol [03] Prologue, FreeTec NC-7104, NC-7159-675 temperature sensor. Is there a way to decode the protocols with RF433recv? Thank you and kind regards, Andreas
