The 13 bits are 12. Do not forget the sync_high before the long snyc_low (10.6ms). Please make also a screenshot of a measure of the high times. Also make a 0xB1 sniffing.

Right, I figured there was a start or stop condition because there are only 12 pins that can be used for input.
I think something which may be problematic (not sure as I have never dug in your code at all) is the fact that the chip is externally biased by a resistor determined by user and this has an impact on the timing (obviously) so I am not sure how one would compensate for that in terms of decoding but to know the first post used 1M resistor and these below are 2 x 1M in parallel... i.e. ~500k?
Will attempt rfraw 0xb1 on the sonoff bridge and see what happens....

Using 1mOhm resistor seems it may lead to something useful ?

Is your osziloscope a real osziloscope? Please meassure each pulse time.
When I take your first screen I get this bucket numbers:
It should be 10101010101010101100101012 instead of 10101010101010101010101012!?
Maybe the tolerance in the code is too big...
I am not realy sure what is a bit 0 and bit 1.
Maybe it is a inverted version of this description:
https://github.com/Portisch/RF-Bridge-EFM8BB1#defining-new-rf-protocols-in-rf_protocolsh
Maybe it is like this:

The one you marked 0 is 1 and the one you marked 1 is 0 in terms of the input I gave to the pin being VCC=1 and GND=0 - So in that case all the pins were VCC except for that one which you marked Bit 1 which was actually LOW.

You are right. But now the firmware make a shot of the high period and low period. And then check if bit 0 or 1.
On your chip it have to be: make a shot of low period and high period. And then check if bit 0 or 1.
I have to think about it how this can be done...

If its not something you think other people will use then its no sweat... i just figured if it was easy to do why not ;) Its just as easy for me to just use a tiny45 and rcswitch lib.. its not as if this is in a device I need.. just picked up 5ps o the chips because they looked interesting.

Ok, tell me which scenario's you want and I'll give you the logic analyzer's output for those?

Would be nice to have a plot of 0xAAA and 0x555. And measure each high and low time. Then I should be able to simulate the signal and check what's wrong with 0xB1 sniffing.

Sure, give me some time I'll do it

So the first one is obviously a start condition.
Then it seems it sends MSB first so 0xAAA results in so
So the logic sent is
1 0 1 0 1 0 1 0 1 0 1 0

Now for the inversion we do 0x555 (0b010101010101) and again we see that the first one is some form of start marker and then short pulse = logic high, long pulse = logic low if one considers MSBit is sent first so data out would be
0 1 0 1 0 1 0 1 0 1 0 1

Sending 0b111111110000
So confirmed, inverted and LSB sent first right after the start condition.

You decreased the speed? Now it is a low time of 2.25ms. Before it was 0.6054ms as I can read on your first screen!?
Now the 0xB1 sniffing looks ok. Maybe I have to speed up the sniffing somehow.
Also I need an idea how to detect an inverted bit diagram. "Normally" it is high followed by low. On yours its low followed by high.
MSB/LSB first isn't a real issue right now.
Thank you very much for all the measurements!

I think it was from 500k resistor to 1 mega ohm resistor - the highest value I have on hand.
I suppose it could be simple enough to invert the signal using a transistor but that would cause the DATA pin on the radio to be high by default which is no good for low power use.

So it seems for a logic 0 the state goes high earlier than for logic 1

Could use 2 x 1M in series to get it to lower some more then maybe you won't need to increase sample time on your side.

Using 2 x 1 Mega Ohm = 2M
Also much more consistent data now

Thx for all the data! I will need to increase the sniffing because of issue #38. There is no chance to change the speed.
My first idea is to implement a new type of protocol what will handled by a negative edge. The current protocols are handled right now on a positive edge.

You're welcome. I also note that I am running an older version of the firmware so Jason tells me you update some stuff recently so I guess I should reflash the EFM chip.

The new firmware is now supporting inverted signals:
https://github.com/Portisch/RF-Bridge-EFM8BB1/releases/tag/0x02
The default pulse time is set here:
RF-Bridge-EFM8BB1/inc/RF_Protocols.h
Line 229 in 89c66ec
This 210µs are equals to a frequency of about 2381Hz.
Hz == 1 / (pulse_time * 2)

You have to find a matching value for your used frequency to use the 0xA6 decode.

The shortest bucket (0x02A8) is the pulse time. So set pulse time to 680 and 0xA6 should work.
Maybe... Then the protocols says: pulse_time * 36 is sync low: 0x02A8 * 36 = 0x5FA0 what is much bigger than 0x5000.
I guess a pulse time between 300-400 would be the best. So adjust your osc to run with ~1666-1250Hz.
