ENC28J60 Ethernet gateway

[Sergio Rius]

@scalz Thanks for your help. Unfortunately I can't get a w5100 in my country and would order it outside. I had those rfms for years and I want to test range before buying a sensebender.
And I'm convinced to stop using the wifi for a gw.

I had hope that any used had the same hw already running.

@kimot I am use one Ethernet gateway about 2 year - work good and stable.

[Sergio Rius]

@cabat Could you please share you pinout for radio and module, and the sketch configuration?
I can't make it work and I don't know if it's a matter of connections or something to activate, like softspi.

@sergio-rius Pinout as described here Building an Ethernet Gateway, i am use module like this:

and my sketch on 20-Feb-2019 is:

#define MY_BAUD_RATE 9600
//#define MY_RF24_PA_LEVEL RF24_PA_MIN
#undef MY_REGISTRATION_FEATURE
#undef MY_CORE_COMPATIBILITY_CHECK

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69

// When ENC28J60 is connected we have to move CE/CSN pins for NRF radio
#define MY_RF24_CE_PIN 5
#define MY_RF24_CS_PIN 6

// Enable gateway ethernet module type 
#define MY_GATEWAY_ENC28J60

// Gateway IP address
#define MY_IP_ADDRESS 192,168,1,235

// The port to keep open on node server mode / or port to contact in client mode
#define MY_PORT 5003   

// Controller ip address. Enables client mode (default is "server" mode). 
// Also enable this if MY_USE_UDP is used and you want sensor data sent somewhere. 
//#define MY_CONTROLLER_IP_ADDRESS 192, 168, 178, 254   
 
// The MAC address can be anything you want but should be unique on your network.
// Newer boards have a MAC address printed on the underside of the PCB, which you can (optionally) use.
// Note that most of the Ardunio examples use  "DEAD BEEF FEED" for the MAC address.
#define MY_MAC_ADDRESS 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED

// Flash leds on rx/tx/err
//#define MY_LEDS_BLINKING_FEATURE

// Set blinking period
//#define MY_DEFAULT_LED_BLINK_PERIOD 300

// Enable inclusion mode
//#define MY_INCLUSION_MODE_FEATURE

// Enable Inclusion mode button on gateway
//#define MY_INCLUSION_BUTTON_FEATURE

// Set inclusion mode duration (in seconds)
//#define MY_INCLUSION_MODE_DURATION 60 

// Digital pin used for inclusion mode button
//#define MY_INCLUSION_MODE_BUTTON_PIN  3 

//#define MY_DEFAULT_ERR_LED_PIN 7  // Error led pin
//#define MY_DEFAULT_RX_LED_PIN  8  // Receive led pin
//#define MY_DEFAULT_TX_LED_PIN  9  // the PCB, on board LED

@scalz said in ENC28J60 Ethernet gateway:

A while back, we checked w5100 module + arduino 328p. Eth module and radio were working on same hw spi bus but in docs it uses softspi, I don't remember why, perhaps for having a dedicated spibus for ethernet..

It may have been fixed by now, but originally the W5100 did not release the SPI bus properly. So, it needed a separate SPI bus from the radio.
I think this was fixed in the W5200 and W5500.

[scalz]

@nagelc
exactly, you're right! Better memory than me :) I remember now, I had to hack w5100 lib for spi transactions to make it working on same bus. So I don't know if it has been fixed.. I hope so.

Noooooo..... Just ordered a W5100 :sob:

@cabat It may not do for me. I'm trying to use rfm69 now. I could not leave my existing network down and brought the nrfs back to where they belonged.

Also the eth module I have here is the shield for nano one. As it stacks below the nano, it may be that is interfering more pins than I expected.

What I would want to know is that the rfm69 needs a different pinout with this shield or not. I can't find any reference that tells me this, so I can start debugging the problem.

[cabat]

@sergio-rius sorry, my mistake, missed of using RFM69 in your setup..

[Sergio Rius]

@cabat Oh, no! Thanks for your help. It has inspired me. Now I'm trying something more.

[Sergio Rius]

I've been fiddling with the radio alone (serial gw), softspi and changing pins, and I think there's something else here.
Well those are my findings:

With this base definition and without the module wired:

#define MY_RADIO_RFM69
#define MY_RFM69_NEW_DRIVER
#define MY_IS_RFM69HW

#define MY_DEBUG_VERBOSE_RFM69

#define MY_GATEWAY_ENC28J60

It works as expected.

0 MCO:BGN:INIT GW,CP=RPNGA---,REL=255,VER=2.3.1
4 TSM:INIT
5 TSF:WUR:MS=0
6 RFM69:INIT
7 RFM69:INIT:PIN,CS=10,IQP=2,IQN=0
11 RFM69:PTX:LEVEL=5 dBm
13 TSM:INIT:TSP OK
15 TSM:INIT:GW MODE
16 TSM:READY:ID=0,PAR=0,DIS=0
19 MCO:REG:NOT NEEDED
72 GWT:TIN:IP=192.168.50.211
1075 MCO:BGN:STP
1077 MCO:BGN:INIT OK,TSP=1
1081 TSM:READY:NWD REQ
1083 RFM69:SWR:SEND,TO=255,SEQ=0,RETRY=0
1088 RFM69:CSMA:RSSI=-98
1090 TSF:MSG:SEND,0-0-255-255,s=255,c=3,t=20,pt=0,l=0,sg=0,ft=0,st=OK:

If I try to change CS pin to any other with #define MY_RFM69_CS_PIN 4 for example, I always get:

0 MCO:BGN:INIT GW,CP=RPNGA---,REL=255,VER=2.3.1
4 TSM:INIT
5 TSF:WUR:MS=0
6 RFM69:INIT
7 RFM69:INIT:PIN,CS=4,IQP=2,IQN=0
11 RFM69:PTX:LEVEL=5 dBm
13 TSM:INIT:TSP OK
14 TSM:INIT:GW MODE
16 TSM:READY:ID=0,PAR=0,DIS=0
19 MCO:REG:NOT NEEDED

So I revert the CS pin change and activate softspi and change irq #define MY_SOFTSPI and #define MY_RFM69_IRQ_PIN 3 And it works well:

0 MCO:BGN:INIT GW,CP=RPNGA---,REL=255,VER=2.3.1
4 TSM:INIT
5 TSF:WUR:MS=0
6 RFM69:INIT
7 RFM69:INIT:PIN,CS=10,IQP=3,IQN=1
11 RFM69:PTX:LEVEL=5 dBm
13 TSM:INIT:TSP OK
15 TSM:INIT:GW MODE
16 TSM:READY:ID=0,PAR=0,DIS=0
19 MCO:REG:NOT NEEDED
72 GWT:TIN:IP=192.168.50.211
1075 MCO:BGN:STP
1077 MCO:BGN:INIT OK,TSP=1
1079 TSM:READY:NWD REQ
1081 RFM69:SWR:SEND,TO=255,SEQ=0,RETRY=0
1086 RFM69:CSMA:RSSI=-98
1091 TSF:MSG:SEND,0-0-255-255,s=255,c=3,t=20,pt=0,l=0,sg=0,ft=0,st=OK:

Then I add the eth module and I get:

0 MCO:BGN:INIT GW,CP=RPNGA---,REL=255,VER=2.3.1
4 TSM:INIT
5 TSF:WUR:MS=0
6 RFM69:INIT
7 RFM69:INIT:PIN,CS=10,IQP=3,IQN=1
11 RFM69:PTX:LEVEL=5 dBm
13 TSM:INIT:TSP OK
15 TSM:INIT:GW MODE
16 TSM:READY:ID=0,PAR=0,DIS=0
19 MCO:REG:NOT NEEDED

And stays here forever.

Of course all those test are made using a double (5v+3v3) good power source, a level shifter... and changing the wires accordingly.

I have some questions:

• Its normal MY_RFM69_CS_PIN not having effect and breaking the radion connection?
  Without being able to change this, I don't know if it's spi interference.
• In the last test, it seems to halt when initialising the network. Doesn't it?
  Is there a way I can further know if the problem is with the eth module? I've tried it alone with the nano and it works.

I would thank guidance for debugging this.
