Bandpass filter problem
#1
Hello everybody,

so I did flash my attiny85 successfully and I had it working fine, filtering false positives on pilight-receive. It would only show my temperature sensors and some smoke detectors. I only have the necessary pins connected (5V, GND, PB3, PB4). But it only worked for a short while.

Now pilight-receive shows the following over and over:

Code:
{
    "message": {
        "version": 3.00,
        "lpf": 80,
        "hpf": 16000
    },
    "origin": "receiver",
    "protocol": "pilight_firmware",
    "uuid": "0000-b8-27-eb-046cca",
    "repeats": 1
}
I don't really know what to make of that. Any ideas?

I believe that I was once able to fix it by connecting the remaining pins, but I am not sure whether that was just an accidental fix.

Thanks for the help!

It's simply telling you that you have an attiny with the pilight firmware connected and what version of the firmware you're using.

You are right that is quite obvious.

My question should have been: Why does it show me that instead of my 433MHz devices?

Probably some wrong connections, because the filter obviously works.

Today I reconnected everything and it works again.

Connections did not change:
ATTiny85 PB3 <-> RaspberryPi 3 Pin 13
ATTiny85 PB4 <-> Receiver Data Pin

If it starts showing the pilight_firmware messages again I will post it here.

So it happened again. Setup and connections were not touched. This is my command line output:

Code:
pi@raspberrypi:~ $ pilight-receive
{
   "message": {
       "device_id": 60480,
       "id": 1,
       "unit": 115,
       "battery": 1,
       "temperature": 10.50
   },
   "origin": "receiver",
   "protocol": "oregon_21",
   "uuid": "0000-b8-27-eb-046cca",
   "repeats": 3
}
{
   "message": {
       "version": 3.00,
       "lpf": 80,
       "hpf": 16000
   },
   "origin": "receiver",
   "protocol": "pilight_firmware",
   "uuid": "0000-b8-27-eb-046cca",
   "repeats": 1
}

From that point on the second message is received over and over again.

So it can't be wrong connections. Any other ideas?

What does over and over mean? In what time period?

It continues receiving the firmware message. I don't have exact timings but it feels like the same time interval at which my temperature sensors send. I can try to time the messages though.

I just timed it. It receives the messages in 1 minute intervals.

I just got a strange one:


Code:
{
    "message": {
        "version": 32769.00,
        "lpf": 0,
        "hpf": 492520
    },
    "origin": "receiver",
    "protocol": "pilight_firmware",
    "uuid": "0000-b8-27-eb-046cca",
    "repeats": 1
}

The 1 minute is what it should be. Can you try the receiver without filter to make sure the receiver isn't the fault?
