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

hlehoux

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 !

hlehoux

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 :-)

I guess this means i finally managed to get it working:

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

hlehoux

@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.

mfalkvidd

@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

hlehoux

@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

hlehoux

@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

electrik

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

hlehoux

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 ....

electrik

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?

hlehoux

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

mine is:

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 ?

electrik

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

Antenna issue ?

You could be right.

What antenna do you have?

hlehoux

Hello, here are 2 photos

one from the back:

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

one from the antenna:

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

hlehoux

@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

electrik

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

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