RPI3 GW poor RSSI on RFM69HW #1077

SimoneBnc · 2018-03-04T15:01:13Z

I have tried compiling the development version on my RPI3 with a RFM69HW radio same as the node (pro mini 3.3v) but I am getting -90dbm RSSI on node with 100% tx power and a bunch of NACKs, while just compiling the stable version on the RPI3 makes the node reporting a -70dbm RSSI with 0% tx power. I also tried both stable and development version on node but the result is the same so it is something wrong on the GW side.
GW is compiled as follow: ./configure --my-transport=rfm69 --my-rfm69-frequency=433 --my-is-rfm69hw --my-gateway=ethernet --my-port=5003, I only added #define MY_RFM69_NETWORKID (27) to the mysgw.cpp

Could you compare the two versions when using the same output power? That would help us determine if the problem is caused by a difference in output power or a difference in code.

SimoneBnc · 2018-03-04T16:39:36Z

The output power is set automatically by ATC, I'm just reading it from node side.

mfalkvidd · 2018-03-04T20:33:28Z

ok. Thanks.

SimoneBnc · 2018-03-04T20:52:29Z

I'll post some rfm69 logs as soon as I can

SimoneBnc · 2018-03-10T15:04:33Z

Here are the logs with latest dev on GW and stable on node as it doesn't make much of a difference.

Looks like there is noise/constant activity on the channel:

CSMA threshold is set to -95dBm (by default), i.e. RSSI above this value are considered as channel activity - you could try setting the threshold lower, e.g. to -85dBm and see if communication/retries improve:

#define MY_RFM69_CSMA_LIMIT_DBM (-85)

ghost · 2018-03-17T14:08:23Z

What fix ?

ghost · 2018-03-18T11:40:54Z

please tell me where is this fix and how i can use it... ?

SimoneBnc · 2018-03-18T13:18:01Z

Only on node.

ghost · 2018-03-18T14:05:07Z

Ok but how use it this fix and whre i found it...

SimoneBnc · 2018-03-18T14:43:20Z

It's for development purposes only, I'm testing with tekka to find out what is the problem

piotrraczynski · 2018-12-31T09:00:10Z

Is there any update on this issue? I'm seeing the same problem using Rpi GW on 2.3.2. Poor TX RSSI (from node perspective) makes ATC unusable.

@SimoneBnc Could you please share the fix you mentioned earlier?

ghost · 2018-12-31T09:13:45Z

For me is still problem. Untill not fix i use MySensors 2.2.0 and it works ok.

SimoneBnc · 2018-12-31T09:30:19Z

Same here, I'm still in 2.2

ghost · 2018-12-31T09:31:40Z

No looks good. Share new version with bug and share next versio also with bug...

piotrraczynski · 2019-01-12T10:04:00Z

I confirm 2.2.0 works OK. Both RSSI on Rpi and ATC.

turboproc · 2019-04-16T09:04:30Z

Hi, was this issue ever solved? Running MySensor version 2.3.2-beta on a AVR 328p / RFM69CW node and a PI3 / RFMCW MQTT gateway I'm experiencing similar issues where the RSSI of messages received by the gateway remain very low (< -85dB) irrespective of the TX level of the node. Distance is only a few meters (< 5).

piotrraczynski · 2019-04-16T09:44:49Z

Hi, I'm not sure I haven't checked it with 2.3.X. For production at my house I'm still using 2.2.0 which works flawlessly for me in that matter. Right now I'm busy working to get hoperf RFM73 working with mysensors (It's a chinese 'clone' of the Nordic NRF24 but with some changes to it, anyway I found it more convenient to use, especially that it's much smaller module in size compared to Nordic nrf24...), which should work but it's currently not. -- Pozdrawiam, Piotr Raczyński wt., 16 kwi 2019 o 11:04 turboproc <notifications@github.com> napisał(a):

OK, let me check how this works with version 2.2.0. If that works flawlessly at my place as well it's time to find the relevant difference between version 2.2.0 and 2.3.X.

ghost · 2019-04-16T10:19:42Z

O dont know why developer not fing this bugs and not fix it for a long time.

SimoneBnc · 2019-04-16T10:53:15Z

It is still beta for a reason I'd say 😀

ghost · 2019-04-16T10:56:03Z

Ok but official release 2.3.1 also has this bug.

turboproc · 2019-04-19T08:58:41Z

OK, did some trial and error and learned that release 2.2.0 works almost perfect, at least regarding this topic. So sticking for now on this release until I understand what can be gained with anything newer.
One further observersation (and I have to dive a bit deeper): I've the impression that the code doing the ATC control at the node is behaving weird which might be caused by the calculation of upper and lower limit of the target RSSI. Once I changed the code by a brutforce calculation of target RSSI + and - 2 (just hard code 68 resp 72 dB) the ATC became much better and more quiet, i.e. not adjsuting the TX level after every message.

speedy-colibri · 2020-06-17T19:59:39Z

Same here, I'm still in 2.2

I had same connection problems like you guys... With MySensors version 2.3.2, the GW and Nodes work okay for about have a day... the RSSI values ranging from -80 to -90, round about. Then I also switched to version 2.2.0. The RSSI values now read about -60. I hope this time the Nodes and GW operate reliably for much longer...

alexelite · 2021-05-04T20:39:30Z

I found the proximate cause for the low Rx RSSI value when radio RFM69 is connected over SPI to Raspberry Pi.
When the radio is connected to an MCU like ATmega328, the delay between the rising of DIO0 (PayloadReady interrupt) and the time the RFM69_interruptHandling is called and radio is put into stand by mode, is is in the order of 40us.
When the same radio is connected directly over Pi's SPI interface, the delay increases to about 3ms. From what I understand the radio does not stop evaluating the RSSI when packet is ready, because I read the RSSI register value multiple times after the Packetready interrupt, before changing the mode to standby, and the RSSI decreases over time.
I was able to replicate the low RSSI value on ATmega328 by adding a 1 to 4 ms delay before putting the radio into stand by.
So the shorter the delay is, the higher the RSSI is.

To test this, I used the radio's AutoMode, to switch from Rx to StandBy with the rising edge of PayloadReady RFM69_REG_AUTOMODES = 0x85 and the RSSI is no longer low. From -80...-90, now up to -27...-30 for same 1 meter distance from GW to node.

If you want to test this, you need to add {RFM69_REG_AUTOMODES, 0x85}, in radio configuration function RFM69_setConfiguration(void) and comment this && (regIrqFlags2 & RFM69_IRQFLAGS2_PAYLOADREADY) in RFM69_interruptHandling(void). All modifications in RFM69_new.cpp. With automode on, the PayloadReady flag is no longer set in register IRQFLAGS2, as it turns out.
I am testing this on the latest dev 2.4.0

In the RFM69_handler(void) function there is a comment // radio is in STDBY but at that time the radio is not in Stand By.

I do not know what is the root cause of this delay, as I wrote here before finding this topic and investigating even more, it happened that my GW worked perfectly once, without any hardware or software modification. So if a fluke made it work, there has to be a root cause.

piotrraczynski · 2021-11-02T09:02:02Z

@alexelite nice debugging! I checked this topic after my controller SW updates to see if this one got resolved. It seems that almost, do you mind submitting a pull request?

alexelite · 2021-11-16T09:31:52Z

@piotrraczynski, did you get a chance to test the fix? For me it works very good. It is the most stable GW after testing multiple alternatives like serial, esp8266-mqtt, esp32-mqtt.
Before and after the fix:

piotrraczynski · 2021-12-27T10:28:57Z

Hi @alexelite, sorry not yet, let me check your fix locally, it seems that CI failed in your PR, but the results are gone? I asked tot rerun the checks itself.

BTW. what did you use for getting RSSI chart like here?

alexelite · 2022-01-03T15:57:00Z

@piotrraczynski, CI failed because the length of one of the lines in the commit message was over the max stated in the rules.
I am not very good with github, so I don't know if I can do anything about the CI, but there are very old PRs that passed all test and have not been reviewed. Unfortunately development seems to have stalled.

About the graphs, I modified the gateway software so for every message received it also publishes an RSSI value, over MQTT.
The actual graph is form a hacked LowPowerLab RaspberryPi-Gateway made to decode mysensors messages also over MQTT.
The code is here

oumuamua119 · 2023-06-22T00:52:56Z

Hi all,

I've been having the same RSSI issue on my RPI gateway.

I used the RFM69_new.cpp file you refer above in my gateway, but the RPI presented an error when I ran "make".

Have you solved this problem using another file? Am I doing something wrong?

Thank you for any advice.

alexelite · 2023-06-22T17:10:02Z

@oumuamua119, I did not change a thing in make. Can you post what error you got? The changes I made were very basic as I remember. It was more than 2 years ago when I submitted the pull request and maybe other things changed in mysensors. I use the same version as I did then.

Hi @alexelite.

Thanks for the response! I repeated the steps I made before and realized I downloaded the wrong file (I did wget on the permalink...). Basic mistake...

I downloaded the right file and it is working perfectly.

Thanks!
