Nodemcu + RFM69. Level converter needed?

[gmccarthy]

After many months of struggling with the poor range of NRF24L01+ (And having tried all the tricks) I'm not trying my luck with the RFM69 radio. (RFM69CW - 868Mhz)

When connecting the rfm69 to the nodemcu (For the ESP8266 gateway), is a 5v to 3.3v logic level converted required?

For the projects listed it says you need one when connecting it to the Arduino but wasn't sure about the Nodemcu.

Also can someone confirm the wiring - its not 100% clear.

Is this correct?

Nodemcu ---> RFM69
D2 ---> N/C
D8 ---> NSS
D5 ---> SCK
D7 ---> MOSI
D6 ---> MISO
N/C ---> D100

And of course GND and VCC (3.3v)

@gmccarthy I don't know about the connections, but the nodemcu is 3.3V so there is no need for a level converter.

[gmccarthy]

Thanks - I can only think my connections are wrong then. Can't get any comms going on the rfm69.

You allso need to connect the DI00 for the RFM69.

[gmccarthy]

@korttoma That probably explains why I can't get it working. Do you know what pin it needs to connect to on the nodemcu?

On this link the DI00 is gray (https://www.mysensors.org/build/connect_radio) but here it doesnt show where to connect it (https://www.mysensors.org/build/esp8266_gateway)

Did you try @chrille wiring:
https://forum.mysensors.org/topic/3061/solved-esp8266-gateway-with-rfm69-wdt-issues/4

exemple here:
https://github.com/janchrillesen/arduino-stuff/blob/master/GatewayESP8266-RFM69.ino

[korttoma]

I do not know about the nodemcu but I connected IRQ (DI00 of RFM69) to GPIO4 on my ESP-07 and added the following line to the sketch:

#define MY_RF69_IRQ_PIN 4

[gmccarthy]

@emc2 Thanks for the link.

I've connected up the missing pin and believe the wiring is all correct. Double checked the wiring on the arduino mini as well to the rfm69 (Via logic converter)

Still can't get it to communicate using DallasTemperatureSensor-RFM69.ino

[emc2]

And you set up the pins radio type in your gateway sketch too right?

// Enables and select radio type (if attached)
#define MY_RADIO_RFM69
#define MY_RFM69_FREQUENCY   RF69_868MHZ
#define MY_RF69_IRQ_PIN 4
#define MY_RF69_SPI_CS 15

[gmccarthy]

@emc2 Yes

[emc2]

I guess you would need to give the logs for the gateway too, to see if you have a radio fail somewhere.

[gmccarthy]

@emc2 This is all I see on the gateway:

[emc2]

It seems good on the gateway to me, no radio error at least.
Past that no idea.

[gmccarthy]

@emc2 Thanks. Will keep digging but I"m almost out of idea as well.

[emc2]

@gmccarthy maybe an interesting read:

[korttoma]

On the arduino mini I think you should connect the DI00 (IRQ) to pin 2 like you see on this page

For some CPU types the IRQ pin is hard coded and can not be re-assigned.

[TON RIJNAARD]

@gmccarthy i have insert this line in the gateway then was it working for me

#define MY_RFM69_PA_LEVEL RF69_PA_LOW

[gmccarthy]

@emc2 Interesting read.

@korttoma I've connected up IRQ line. Still no luck,

@TON-RIJNAARD Have tried that now as well. No luck.

Tried going back to basics and now have 2 x Arduino pros with RFM69 - both loaded with pingpong script.

Don't know where I'm going wrong but I can't even start the script - entering 1 or T does nothing. (I"ve used the script before with the NRF radio and it works)

Have also tried the latest dev version.

Just keep getting this on both arduinos:
