JP1 Remotes

The serial number of FTDI chips can be overwritten by the FT_PROG utility .
As far as I know genuine IDs start with "FT" followed by 6 alphanumeric characters. See this KB article.

The KB article only says "a 2-letter prefix like FT". It appears that the prefix can be any two characters. The ...

that folder seems to have accidentally been dropped starting with v3.2.13, if you download versions v3.2.0 and before, it's there

I have traced the omission to a change of computer used for building RMIR versions. I have fixed this in the new computer so JP1_Arduino.ino will now get included ...

Sorry about that. I will restore it in the next build.
I have spent some time in the last few days trying to find what I thought was a bug. Something in the setup of ...

Can you tell the difference between a genuine FTDI chip and a clone by looking at it? I have a SparkFun FT232R Breakout Board, the chip clearly says FTDI FT232RL but I have doubts that it is genuine. In my current work with a URC7981, I have tried all the FTDI USB to Serial cables I have. These ...

Glad to hear it! It is a long time since I used those Bluetooth extenders, so nice to know they still work and are useful. I am still working on the URC7981 and have today started on a new line of attack which I think is promising.

I have seem Extenders in v1 and v2 here in the filebase. It is written that v1 works with BLED-Dongle whereas v2 is described to work with Windows Driver. I wonder if v2 is also still compatible with the BLED-Dongle?

Yes, v2 extends the capabilities of v1. You need to install v1 then use it to ...

Just to keep you informed, in the past few days I have made significant progress in understanding the processor of the URC7981. Nowhere near enough to make it work with RMIR but helpful nevertheless. I see that you have moved to a URC7880 but I am working on the URC7981 for my own interest as it is ...

if there is any "developer tip jar" or "hardware funding" I would definitely consider such "support"; please let me know!
I and the other developers work for the pleasure the challenges give us and for the knowledge that we are helping other users. We do not want or accept financial support, but ...

I wrote above about the URC-7981 that I was trying to open the remote but having great difficulty. I persisted and finally succeeded. I have soldered in the 6-pin connector in the "standard" way that Rob described. The pins are then a tiny bit too long to easily close the battery compartment, though ...

Very interesting. However they soldered the pins, they must have accessed the back of the PCB. I am currently trying to open the remote but having great difficulty. Following 3FG's instructions for the 7980, I have been able to get as far as releasing the lowest clip on each side, the ones nearest ...

As you know, there are two possible ways for RMIR to interact with the URC-7981. One is with Bluetooth, the other is with the 6-pin connector. Both present considerable problems. The Bluetooth access is designed for use with the OfA Advanced Setup phone app, not for general Bluetooth access, and ...

I have installed the OFA Advanced app on my Android phone and will get a URC 7981 so that I can investigate this. It looks identical to the URC 7980, which I have. However, the 7980 is not supported by the OFA Advanced app but it does have the 6-pin connector fitted. I do not like either soldering ...

Please try development build RMIR v3.2.13 which I have just posted in the RMIR Development folder on SourceForge. I think this should solve the issue.

I have only just seen your post. I can reproduce the problem and will look into it.

Apologies for not dealing with this sooner, but I have been absent from the forum while recovering from a broken pelvis. I have now posted development build 12 in the RMIR Development folder on SourceForge which is my best attempt to resolve the problem. Here is an explanation.

The Receiver Power ...
