Help needed to setup a RFM69 & ESP8266 Gateaway on Adafruit Feather Huzzah



  • Hello, i'm trying to setup a gateaway on ESP8266 like explained in https://www.mysensors.org/build/esp8266_gateway but i don't have a NodeMCU or Wemos D1 Mini.

    I have an Adafruit Huzzah Feather and i can't figure out what pins to use for connecting to DIO0 and NSS on the RFM69 even though my sketch compiles and uploads correctly .

    Anyone can help, or have a working GatewayESP8266.ino for the Huzzah ?

    Many thanks !



  • Here is what i have tried:
    I try using GPIO 2 and 15 to pilot the RFM69

    here an extract of my GatewayESP8266.ino

    // Enable debug prints to serial monitor
    #define MY_DEBUG
    
    // Use a bit lower baudrate for serial prints on ESP8266 than default in MyConfig.h
    #define MY_BAUD_RATE 9600
    
    // Enables and select radio type (if attached)
    //#define MY_RADIO_RF24
    #define MY_RADIO_RFM69
    
    #define MY_IS_RFM69HW // Omit if your RFM is not "H"
    #define MY_RFM69_IRQ_PIN 2
    #define MY_RFM69_IRQ_NUM MY_RFM69_IRQ_PIN
    #define MY_RFM69_CS_PIN 15 // NSS. Use MY_RFM69_SPI_CS for older versions (before 2.2.0)
    
    ../..
    
    void setup()
    {
       pinMode(MY_RFM69_IRQ_PIN, OUTPUT);
       pinMode(MY_RFM69_CS_PIN, OUTPUT);
    
    	// Setup locally attached sensors
    }
    
    ../..
    
    void loop()
    {
    	// Send locally attached sensors data here
      digitalWrite(MY_RFM69_IRQ_PIN, HIGH);
    delay(1000);
    digitalWrite(MY_RFM69_IRQ_PIN, LOW);
    delay(1000);
    }
    

    What's going wrong is i need to unplug the wire to GPIO2 at boot time unless it won't boot
    then if i do that and replug the wire after boot, TFM is not initialized properly and
    i get this log:

    My knowlegde in electronics is level zero unfortunalty
    The adafruit Huzzah documentation states that
    GPIO #2, is also used to detect boot-mode. It also is connected to the blue LED that is near the WiFi antenna. It has a pullup resistor connected to it, and you can use it as any output (like #0) and blink the blue LED.

    So i thought i could wire directly GPIO2 to DIO0 on the RFM69 like explained https://www.mysensors.org/build/connect_radio but obviously i do something wrong

    Please Help 🙂

    Nice work @hlehoux
    Is there any information we could add to the radio connection page to help other Feather users?



  • @mfalkvidd

    Hello, certainly yes; anyhow, my setup is quite experimental yet:

    • my antenna setup is quite bad, i loose radio messages or don't receive Ack from the gateway (my bad, i have 868 MHz RFM69 and ordered antennas for 433 MHz)
    • i can confirm it works with NSS on pin GPIO#15 and IRQ_PIN on GPIO#0 orGPIO#2
    • i have not resolved yet the problem of GPIO#0 and GPIO#2 being used by ESP8266 to detect boot-mode so you have to connect the pin after booting which is very annoying
      There are articles like this one https://www.instructables.com/id/ESP8266-Using-GPIO0-GPIO2-as-inputs/ but i'm quite newbie in electronics...

    I will post more details when my config is better.


  • Mod

    @hlehoux is there a reason you can't use gpio5 for irq? That's what I used on a different esp board when verifying the instructions on https://www.mysensors.org/build/connect_radio



  • @mfalkvidd Well i'm not sure, on [huzzah pinout](link url) GPIO#4 and GPIO#5 are described about I2C SDA & SCL and GPIO #12/13/14 are the same as SCK/MOSI/MISO so i thought would be better not to use them.

    I will try and report back.

    Seems to me (first try) that GPIO#2 works well, provided you connect it both to VCC (it has a pullup resistor ) to avoid boot-mode and to IRQ



  • @mfalkvidd thank you for pointing this to me. I confirm gpio5 works well for IRQ. I read too many articles about how to use gpio0 or gpio2 !

    Anyway i still get very bad transmission ratio, even with very close distance and after buying antennas the good size for my 868 MHz RFM69s

    Can some of you guys point me to help on how to troubleshoot transmissions and/or bad antenna setup for the RFM69, for a newbie like me ?

    Thank you



  • Can you switch on MY_DEBUG_VERBOSE_RFM69 in your node and post the output?
    Also post the sketch please.



  • Thank you for offering help!

    Here is the output of my node "AT Startup" with MY_DEBUG_VERBOSE_RFM69

  • I'm also reading a few posts like this one trying to understand a bit more ....



  • Are you sure about ask your hardware versions? I bought rfm69 modules and I thought they were the HW version but they turned out to be the normal ones.
    So important is

    • module version
    • frequency

    It looks like even with a high rssi your reception is not good. But maybe I interpret this the wrong way. Can I've of the developers or more experienced help with the analysis?



  • Thank you @electrik
    My intent is to use RFM69HW 868Mhz
    I compared with photos on the internet like here

    mine is:
    IMG_0359.jpg

    as far as i understand my reading my RSSI values seem to tell my signal is very weak and noisy ?
    I tried to provide the pwr to the rfm69 with an external source instead of the esp8266 but i was not better.



  • @hlehoux Hi!
    I had quite alot of trouble with NRF24 modules with shaky connections despite doing everything that has been discussed in forum with power supply etc and have ordered a bunch of RFM69's to hopefully improve this according to others in forum claiming better stability with RFM''s. Haven't tested yet but reading this is a bit dissapointing.
    One thing though. Readings in log shows very high RSSI values and if it is measured in dBm this is very bad. The lower value the better I believe. Antenna issue ?



  • @hlehoux can you take a photo from the back also? There should be a table telling which one it is exactly.

    @hakha4 said in Help needed to setup a RFM69 & ESP8266 Gateaway on Adafruit Feather Huzzah:

    Antenna issue ?

    You could be right.

    What antenna do you have?



  • Hello, here are 2 photos

    one from the back:
    IMG_0360.jpg

    I'm not sure what the "W" means, i read chinese copy don't have it ?

    one from the antenna:
    IMG_0361.jpg
    It should be the good size for 868 MHz

    I don't use "ground plane" or sort of, would this explain so bad RSSI ?

    Thank you again for your help and patience



  • @hakha4 i also have several NRF24 nodes and gateaway
    After trying several antenna/tranceiver, i recommend using
    "E01-ML01DP5 Long Range SPI nRF24L01P 2.4Ghz 100mW SMA Antenna IoT Wireless Transceiver Transmitter Receiver nRF24L01P RF Module"

    as a repeater
    It gives far better range results

    Anyway i wanted to try RFM69 to avoid having many repeaters



  • The modules correspond to what it should be.
    It looks like your ground is connected to the ANT pin on the picture, on the bottom side of the PCB?



  • @hlehoux Hi!
    I'm not sure what the "W" means, i read chinese copy don't have it ?

    W means the low power output variant (+13dBm). There is another version named 'HW' which give a higher transmission output (+20 dBM). As elektik pointed out, check out the solder of the antenna. Did the antenna come presoldered or you did it yourself?
    Another option for the coiled antenna is a straight copper wire (8,6 cm long) that gives better transmission according to many sources. Google! theres's alot information about this



  • @hakha4 said in Help needed to setup a RFM69 & ESP8266 Gateaway on Adafruit Feather Huzzah:

    There is another version named 'HW' which give a higher transmission output (+20 dBM).

    There is a black spot on the PCB after "69H" and after the "W" so this is the RFM69HW


  • Hardware Contributor

    @hlehoux
    unfortunately, lot of devboards have non-optimized gnd plane for RF, especially for subghz (small or splitted gnd plane by routes..).
    Moreover, devboard+dupont cable+external rf module is not ideal.
    With rfm69, you should get a nice range.
    Though, why on one of your picture, antenna seems shorted to gnd??
    Imho I would have chosen something else than esp8266 (esp32??) in your case, but your choice 🙂

    To check if this is related to your gnd plane and your build is ok, you could also try to hook two straight wires as a dipole antenna to your radio (one to ANA, the other to GND in opposite direction will replace a ground plane). Google for examples, it's simple to try



  • @scalz
    Could you explain how to read these rssi reports, and how to adjust the configuration of the nodes so the reliability goes up?
    I know there is a setting RFM69_TARGET_RSSI_DBM but it is not clear for me how to use this exactly.



  • @electrik Thank you! What you see is the "head" of the pliers i used to hold the RFM69. I will check again my soldering but definitly ANT and ground should not be connected



  • @scalz Thank you very much!
    Unfortunatly, the antenna seems shorted to ground only because this is the "head" of the pliers i used to take the photo.

    i use esp8266 because i received for free a lot of many adafruit huzzah feathers 🙂

    i will try your suggestion to hook two straight wires as a dipole antenna and report if this is better.

    For sure my "development" setup is devboard+dupont cable+external rf and this should not be the final version ; anyway loosing 50% of messages with distance of 1 meter is disappointing.





  • try adding :

    #define MY_RFM69_FREQUENCY   RFM69_868MHZ
    

    just in case....

    My first prototype using dupont cables and piece of wire as antenna gave me 500m range with 3 or 4 houses between me and gateway.
    Try old driver, no RSSI reporting, but my whole network runs on old driver.

    @hlehoux 1m range is usually caused by radio type misconfiguration, like running HW radio as low power or other way round. Another possibility is faulty radio.



  • Strangely, i also have another bunch of RFM69s that are marked as H but not W. What does it mean ?



  • @hlehoux no idea, i have mix of HW, W and H marked, all play together nicely.


  • Hardware Contributor

    @electrik
    in logs, RFM69:CSMA:RSSI=-104 is the noise floor
    and RFM69_TARGET_RSSI_DBM define the rssi you want to have for your node.

    so if you have a noise floor of -100, you could adjust your target to -85 or less. But maybe you could get a few retries with -90 target.

    rfm69 power level can be adjusted from -18 to +13db. 13db=100% power= 45mA power consumption.

    for example, let's say your target is -70, and your power level has been autoadjusted to +5.
    then if you set, the target to -80 or less, power level will decrease to maybe -8 or even less, it depends on your environment and your build.
    And vice versa, if you set target to -50, ATC will set a higher power level.

    ATC is used to auto-adjust radio power level consumption for battery nodes, so they use only energy they need. This also make your rf environment "greener". No nodes sending loud messages if not needed.

    Another example, I recently designed a new node. Noise floor here is around -98db.
    With a target of -70 if I remember, power level was autoadjusted to +5db.
    After adjusting target to -87db, power level has decreased to -11db, which equals to 20% power.
    And there are no NACK nor retries.
    So this node now requires less energy for sending messages and that will save battery.
    This is for an indoor node, 10m distance with 2 brick walls obstacles.

    old driver doesn't have ATC management. I've no problem so far with new driver.

    I guess H would mean High power version. But to be sure, yuo just have to google for rfm69 pics and you'll see which version you have. Existing versions are : RFM69HW, RFM69W, RFM69HCW, RFM69CW



  • @scalz great explanation of new driver functionality.
    Some cheapest Aliexpress boards are not marked at all or marked with Frequency only. H versions have additional sot23-6 chip near antenna pin.

    Wonder why the new driver wasn't stable enough to do 12kB OTA firmware update even once, regardless of settings 🤔 . Same GW and node works flawlessly on old driver over 10-100 meters.


  • Hardware Contributor

    @Sasquatch
    yes rfm modules are nice for long range.
    ok. we will re-test OTA+new driver on my new board soon, and will keep you updated

    I agree seems OP has setup problem, could be

    • H vs non-H define
    • IRQ is not triggering for receiving msg
    • weak GND counterpoise for antenna,
    • power supply. For power I usually use 100uf+0.1uf close to the module. 100uf when it's batt powered (for coincell, I like to have two big capa+0.1uf), else it's possible to use a smaller value like 33-47uf


  • @scalz I do agree,
    I found that even USB powered NodeMCU gateway needed at least 10uf ceramic or 47uF electrolytic capacitor on radio supply, without it heavy traffic was causing gateway freezes and reboots. There is 100nF capacotor on rfm69 and 220nf on RFM69H modules(at least my Aliexpress cheap clones have them) right next to the VCC pin, so i skip the external one.


  • Hardware Contributor

    @Sasquatch
    I admit I never checked that, but thought the capa would probably be there.
    well, I usually am careful so I add more footprints than needed for flexibilty, just in case 🙂

    @hlehoux perhaps do you have some arduino mini pro (8mhz 3v) that you could use as a test node and check if you still have same problem (in case this is an IRQ issue..) ?



  • @scalz @Sasquatch Thank you for suggestions, i will test next week-end
    My gateaway is an esp8266 adafruit huzzah feather and my node arduino mini pro (8mhz 3v) using the psb of @sundberg84 ([here])(https://www.openhardware.io/view/389/EasyNewbie-PCB-RFM69-HWW-edition-for-MySensors)

    I did not place any capacitor on the gateway, which is usb powered in my tests.
    I will try to connect a decoupling capacitor like explained here like 47uF



  • Hello, i don't see progress when connecting a 10uF decoupling capacitor.

    On my node i get
