    @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.

              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.

                    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?

                            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

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

                                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

                                  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.

                                    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?

                                    @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.

                                        @hlehoux Here is a useful link how to do that: https://learn.sparkfun.com/tutorials/rfm69hcw-hookup-guide/the-antenna

                                          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.
