Yet another fight against my RFM69

  • Contest Winner

    There must be something I constantly do wrong since looks like I'm one of the few dealing always with similar issues 🙂
    I have a sleeping sensor waking up every minute and wait some commands from the controller. It used to work ok but at a certain point it stopped executing my orders. I could see it reporting awake and sleeping but no more activating the attached relay as instructed. I initially thought was due to the distance so I took it close the gw and the issue was still there. I had a look at the logs and there were a lot of re-transmission and during those my remote command was lost (which makes sense). For completeness, I'm testing the new RFM69 driver with the latest patch @tekka put together but I don't think this is related. Here are the logs:

    First of all why getting a NACK with an excellent RSSI of 30 is strange. But now it comes the weird part. I restarted the gw, and the sensor was back again working fine....for a few minutes, then the same bad behavior was there again. I restarted the sensor a few times and always the same problem but finally after another reboot it was still ok (and consistently ok). Which tells me...well nothing to me 🙂 Bad wiring? Or since I have a 50v/10uF capacitor between the radio vcc and gnd, it is not charging fast enough and "cuts" out the power?

  • Hardware Contributor


    • what's your GW setup? (mcu, and gateway mode)
    • what's your node hardware, especially mcu, do you change clocks during sketch, and which one do you use, which RFM69 variant too (high power or not) ?
    • how are relays connected to your node (could be some noise too..)

  • Contest Winner

    @scalz sorry I always forget to add all the relevant information 🙂 The hw is a serial gw (pro mini 3.3v attached to a Rpi usb port), the node is another 3.3v pro mini powered by AA batteries. Both running at 1Mhz (which with the new driver is working fine provided all the nodes are running at the same speed) and I'm using tekka's which is initializing both the gw and the node at max power and since then I had no more range issues. Btw the logs above have been take with ATC disabled but I had similar logs with it enabled. The relay is connected to an arduino's pin and powered independently.

    I must say I have another three nodes running without a problem with a similar configuration since a few weeks now. Since the last reboot also this one is running perfectly once again. I remember I had a similar issue with another node, same configuration, after a few times I plugged in and out again and again it stared running fine and it is doing so since then. Like if it starts in a good shape, it will continue to do so, if it doesn't, oh then begins the troubles 🙂

    Just a quick update after 24 hours. I don't see anymore re-transmissions (no more duplicated messages on the gateway) and the relay is always triggering. Once again, if it starts in a good shape, everything goes well. But sooner or later I need to identify the real issue 🙂 Cannot be software since the sketch is the same, cannot be hardware I think since the hw is the same, cannot be the distance since yesterday the behavior was the same, when both far away or very close to the gw. Maybe when I move it around I somehow touch something not very well connected but this does not explain how it could happen with another node and only with a RFM69. Who knows 🙂

  • Hardware Contributor

    no clue on my side.. we could also imagine for instance:

    • different "environment" parameters influencing RF
    • a little bit different antenna (i'm exagerating a bit i think), or difference in assembly
    • collision..
    • different mcu or radio quality
    • how much remaining memory do you have after compilation
    • i know 10uF should be enough, but i generally use this for nrf, and add a bit more in case for rfm69 as it uses more power (but that depends on the power supply i use too).

    I almost already know your reply to this 🙂 Some points are maybe irrelevant for your case, these are just there for ref. I'm like you, i don't trust in mystical issues 😉

  • Contest Winner

    @scalz thanks, well, nothing is irrelevant, when not working there must be at least one of your points above which I'm not considering enough 🙂
    Now it is still working well, checking in every minute without a single duplicated message in the controller even if far away from the gw and the remote relay triggering when requested. I should probably do a better job in replicating the issue to at least limit the possible causes...I'll report back in the future with better data I hope 🙂 Thanks!
