Issues with NACK on RFM69HW



  • Re: EasyPCB and RFM69 Issues

    Following on from the thread above I have done some further debugging to try narrow down the issue.

    My setup currently is 3x EasyPCB nodes, non H version of the RFM69. Powered by debugger but also attached battery power.

    They sync up very very sporadically. Most of the time they will not talk to the gateway.

    My gateway is a D1 mini with the H version of the radio. I have tried 2 different radios and both perform the same.

    Antenna type on everything is the coiled versions common on ebay but i have experimented with the SMA style antenna on a node and a 17cm dipole on the gateway

    Everything is running on 433mhz.

    I have tried the new driver option on both the sensor and gateway but same issue. Looks like I only have 1 way communications?

    Things I have tried

    • Double checking the soldering
    • Building multiple gateways and using different radios on the gateway
    • Moving the sensors very close or few meters apart
    • Using a radio on the gateway with a 17cm wire as apposed to the coiled antena

    So the current status is they gain 2 way comms occasionally and when they're within 5cm. The range is very very small!

    Anybody got any ideas what I could try next? Is there a way to confirm the ebay seller has sold me the correct frequency radios? Should I look more into the antennas perhaps? I have tried a dipole and have a node with both the coiled ebay antennas and an SMA one but the results are always the same.

    If the vendor had sold me the wrong frequency radios is there any way to check? Would it cause severe range issues like this?

    @ryanmt great work on the troubleshooting so far. You've covered all the test scenarios we usually use.

    One thing you could do is to define MY_SIGNAL_REPORT_ENABLED. I have not tried it myself and I am not sure how the report is displayed, but it should give some additional info on the signal levels.

    Perhaps defining MY_RFM69_ATC_MODE_DISABLED can help, to get rid of the possibility that ATC messes things up (it shouldn't, but who knows?)

    You could also enable MY_DEBUG_VERBOSE_RFM69 which will give additional debug output.

    I have configured my gateway to report signal levels. You are welcome to use my sketch for inspiration if you find it useful.

    As for the right frequency, one way is to just set your frequency to the other supported frequencies (315, 433, 868, 915) and see if you can get messages through. The loss of signal for using the wrong frequency seems to be 20 to 80dB, depending on frequency so it could absolutely cause this type of problem.

    I am not aware of any external marking or a register to read to figure out which model you've got.

    https://forum.mysensors.org/topic/4741/rfm69-frequency-question might give some extra insight into how the rfm69 radios work.

    If you have a SDR, you could use it to check the signal strength.

    Look also at my project on how to read RSSI and tx power that are also nice info for debugging.

  • Thanks guys,

    I tried enabling #define MY_SIGNAL_REPORT_ENABLED but it made no difference to the output.

    Also tried a few of those sketches but neither would compile properly - I guess im missing something!

    Just bought this
    https://www.ebay.co.uk/itm/162961285195
    now for a long wait from China!


  • Hardware Contributor

    @ryanmt sorry I have missed this thread. I'm following now as well if I can help out with any hardware questions.

    How are you powering the nodes? (Booster or lowered bod?) Can you upload a picture of the nodes and gateway? Sometimes more eyes can spot something.

    You should not power the nodes both with the debugger and battery. Please de-attach the VCC from ftdi debugger. You should only have Gnd rx and TX connected while debugging. Rst can be connectws if you want.

    The biggest concern is in most cases power or antenna.


  • Mod

    @ryanmt if you tried my sketch it would not compile since you are probably missing the display libraries, but you should just use the code that reads the rssi and power info and than print those values either on serial debug or another lcd screen you may have



  • Got my SDR and installed the software.

    Seems to work well, on 433mhz I can see signals from my car keyfob etc.

    When my sensors are powered on though - nothing, looks like nothing is broadcast atall.

    Stumped now. properly stumped 😞 When I get time I will perhaps try a non mysensors sketch to activate the radio see if I can get any TX then. Does anybody have any good sensors?

    I want to think its a bad batch of radios but they are from 3 different sellers.


  • Mod

    you could try to compile the sketch with the 866 and 916Mhz andd see if by change some signal shows up



  • @ryanmt can you please try to use any AVR instead of Wemos for the GW?
    Are you 100% sure you have HW version?

    Try with and without

    define MY_IS_RFM69HW
