ESP32 Using ESP NOW and Bluetooth

@huckohio My concern is that sometime in the future it may not. This is unprecedented, in all the years I have been involved in software this is the only time I have encountered a Corporation intentionally breaking their own code with no explanation or warning or workarounds. IF you can get PlatformIO to work for you it solves the problem the right way, you put a copy of the library in your sketch folder and now it is frozen. The problem is I don't know if that concept works with the board level libraries. Good luck.

I received the IR receivers last night and did some testing based on Bill's IR Remote video (video).  I used a Uno with the IRMP library and ran both the SimpleReceiver and AllProtocols sketches from the example folder.  I also connected my data analyzer to the receiver to make sure the receiver was processing data.

I tested several of my remotes in the house and they all worked fine. These new two pics are from my TV remote.

But when I test the Chicken Coop door remote I get nothing either in the serial monitor or on the data analyzer.  In the AllProtocols sketch I did set the parameters for all protocols.  Received nothing in the serial monitor or on the data analyzer (data analyzer has limited IR protocols to select from).

Here is a pic of the board (this might provide a clue to somebody).

I would appreciate any suggestions you may have.

Thanks

@huckohio Maybe it means nothing, but that string of numbers and alpha ends in RF V1.1. Are you positive it's IR?

@zander

No, not sure.  When I asked the manufacturer for the BT info they said it uses IR.  There's only an LED in the remote.   

@huckohio No problem, strange that it has RF when it's IR tho. Have you googled any of the chips?

@zander 

Ron,

There are no markings on the 8-pin IC.  There is what looks like a 13.560 crystal that appears to be used for 433MHZ rx/tx.  When I look at the 433Mhz boards they have a feed through on the PCB for an antenna - not an LED.  There is a 6-pin chip labeled F115.  When I google F115 it's associated with 433Mhz.  I can't see anything else to google.  

@zander 

Ron,

I have a Kingst Logic Analyzer that I am using that have different protocols you can use.  I've added the IR protocols, PWM, and UART.  The pics list other protocols available.  Any of these I should try (before I add them all in)?

@huckohio That is Radio stuff, were you expecting that in addition to IR?

@huckohio No idea. I noticed the following on the Amazon page near the bottom. The 360 degrees sounds more radio than IR, the long distance sounds more LORA radio (433mHz) than IR. If you have a 433 mHz LORA setup, see if you can connect, or maybe just look and see if there is a tiny antenna, no bigger than your pinky finger.

@huckohio What does the other side of the board look like. If it's IR, where is the receiver, it should be obvious, and if LORA (433mhz) radio either a tiny antenna or traces on the board. They may have shipped the wrong remote, so don't go by that.

@huckohio I think I misunderstood you. I thought you said there was an antenna feed-through, but now I think you are saying it isn't there but an LED is there.  That's a new one for me.

Do you have a pic of the Door Remote?

I'm not getting the sense that the mfg. info is solid.

Actually, my first thought was BT.  But I tested the range and it was approximately 160 feet from the house.  Too far for BT.  I contacted the support line and asked if the remote uses BT and they said it was IR.

Agree, the 433 sounds like LoRa, but the range doesn't match.  I have LoRa sensors over 200 feet from the house and they work fine.  This remote worked for ~160 feet.

The receiver is in the Coop door and there is no sign of an antenna in the receiver or the remote.  There is no antenna in the remote (See pics).

Sorry for the confusion.  When I was googling the crystal I found where that crystal was used in 433Mhz transmitter/receivers (not my remote or the IR units I purchased).  Looking at these boards it was obvious there was a feed through for an antenna.  The remote has no such feed through. 

Another bit of info.  When you press any button on the remote you can see the LED flash through the lens on the remote case.  That's why I think it's IR, just a different protocol or frequency that my receivers cannot see.

Thanks for the comments/questions!

Mike

@huckohio I checked, and although it's common for IR to operate in the 38mhz band, it will also work in GHZ and even THZ bands. I am guessing they used existing 433mhz parts but stuck an IR LED on the output.

Sorry, I don't have any more ideas, I think you already perused all of Bill's stuff, I can't do better than that.

Good luck, and let us know what you eventually find.

@zander 

Thanks Ron.  Always appreciate your input/insight.
