[SOLVED] W5100 Ethernet gateway with RFM69 Radio fails at init

[korttoma]

Hi, softSPI does not work with with the RFM69 yet. You need to use the same SPI pins for both W5100 and the radio.

@jpaulin describes how in this thread

[Frédéric Grandjean]

Hi Korttoma,
Thanks a lot, I didn't find this thread.
I have now lot's of improvements. Now gateway boots,and radio is OK.
But when it shows the IP address, seems it reboots ... constantly.

@Frédéric-Grandjean Try reverting the AVR board package, as described here: https://forum.mysensors.org/topic/4680/mysensors-2-0-ethernet-gateway-atmega-w5100-restart-all-time/3

[Frédéric Grandjean]

Perfect, thank you.
That solved all issues! Now working super fine.

[Jonathan Caes]

Hi, Frédéric Grandjean

I'm also trying to build an ethernet gateway with the rfm69 radio's. But also have some errors when testing the code. Also I'm not sure I connected everything the right way, because there's not that info about those modules.
Since you have this al working now, is it possible for me to take a look at your code and maybe show me how you connected everything?

Thank you!
Jonathan

[Frédéric Grandjean]

Hi Jonathan,
Before I show my code, please check:

• Connect W5100 and radio like this

Arduino - Radio - Ethernet
13      - SCK   - SCK
12      - MISO  - MISO/SO
11      - MOSI  - MOSI/SI
10      - NSS (CS)
7       -       - SS/CS
2       - DIO0  -

Be sure to power the W5100 with 5V and the radio with 3v3!

Then, you need to modify the w5100.h file to disable radio interruption during SPI use:
Find

#else
  inline static void initSS()    { DDRB  |=  _BV(2); };
  inline static void setSS()     { PORTB &= ~_BV(2); };
  inline static void resetSS()   { PORTB |=  _BV(2); };
#endif

and replace with

#elif defined(W5100SPIPATCH)
  inline static void initSS()    { DDRD  |=  _BV(7); };
  inline static void setSS()     { cli(); PORTD &= ~_BV(7); };
  inline static void resetSS()   { PORTD |=  _BV(7); sei(); };
#endif

Then, downgrade the board manager "Arduino AVR boards" to version 1.6.11 and rebuild.

Finally, here is my working code:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the ethernet link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
 *
 * LED purposes:
 * - To use the feature, uncomment MY_DEFAULT_xxx_LED_PIN in the sketch below
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error
 *
 * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

@Frédéric-Grandjean
Thank you for replying so quickly!
I`m going to try this as quickly as possible and let you know how it went.
Thanks!

[Jonathan Caes]

@Frédéric-Grandjean Have to wait untill my level converters are arriving.. also don't have enough transistors laying around to make one my self.. did you use a level converter, probably you did?

[Frédéric Grandjean]

Yes of course I used a level converter. Ordered the one proposed on the radio page. Works well!

[Jonathan Caes]

@Frédéric-Grandjean
Hey, I'm finally working on the gateway.
But the problem is that I can't seem to find the w5100.h file.. :s
Can you maybe tell me where I can find it?

Greetings

[Jonathan Caes]

@Frédéric-Grandjean
Hi again, because I'm a mac user didn't find the w5100.h file. after I took my laptop and searched for the file I found it.
after I replaced the code in the w5100.h file and changed the gateway code and complied I got these errors:
and it went on.

but when I changed the code in the w5100.h file from this:

#elif defined(W5100SPIPATCH)	
      inline static void initSS()    { DDRD  |=  _BV(7); };
      inline static void setSS()     { cli(); PORTD &= ~_BV(7); };
      inline static void resetSS()   { PORTD |=  _BV(7); sei(); };
    #endif

To this:

#else	//This doesn't work => elif defined(W5100SPIPATCH)
      inline static void initSS()    { DDRD  |=  _BV(7); };
      inline static void setSS()     { cli(); PORTD &= ~_BV(7); };
      inline static void resetSS()   { PORTD |=  _BV(7); sei(); };
    #endif

it compiled without any errors.
So I uploaded the code and opened the serial debugging window in which I get this:

I don't know how to fix this, do you know maybe?

Thanks!!
Greetings!

Jonathan Caes - i used your amended #else code in W5100.h file, along with wiring/pinout from Frédéric Grandjean, and example Mysensors MQTTClientGateway sketch and got a ProMiniMQTTW5100Gateway working.
You are trying Ethernet gateway (not MQTT like me), but i think you may have a radio problem - i used 10uF and 1uF caps for the RFM69 radio and separate 3.3V supply (havent tried powering radio directly from ProMini VCC though.

[abrasha]

@Jonathan-Caes @Frédéric-Grandjean
if i use w5100 shield on uno - so i cant connect the pins how i want - means w5100 cs stays on pin 10.
what should i do?

[Tris]

For W5100 shield on Uno with RF69 as a Gateway, i used:
DI00 - Pin 2
NSS - Pin 4 (3.3v level shifter)
MOSI - Pin A1 (3.3v level shifter)
MISO - Pin A2
SCK - Pin A0 (3.3v level shifter)

Leave as pins 14/15/16 in MyConfig.h file - the Uno uses digital pins 14-16 physically as A0-A3.

Using a level shifter makes the ProMini more viable as it is 3.3v and you dont need a shifter.

[abrasha]

@Tris with or without w5100. H mod?

[Tris]

I THINK with the W5100.h file amended.

try using Mysensors ClearEepromConfig too

[abrasha]

@Tris thanks a lot. I'll check it on Sunday.

Btw i use adafruit rfm69hw breakout so no level shifter needed, but i need to post my fix for it because it needs my transport.h mod

[Jonathan Caes]

@Tris But I don't necessarily have to use the mqttw5100gateway, do I? Because I don't really know what you can do with mqtt, what the advantage is of that.

I'm also using seperate 3.3V and a 4.7µF capacitor for the radio.

Here is my schematic I used. I etched my own pcb for this and I think everything looks correct.

[Tris]

The Ethernet and MQTT wiring is the same (according to main MySesnors instructions).

As far as protocols go, I choose the MQTT route because its simple and lightwieght, tipped to be a big player in IoT.

Im not a Mysensors expert, more of a hardware guy, but briefly looking at your diagram - i havent grounded the reset pin on the RFM69 like you have.
Try cutting that track so it floats

[Jonathan Caes]

@Tris That can indeed be the fault, because i was looking at the hoop up page from sparfun (https://learn.sparkfun.com/tutorials/rfm69hcw-hookup-guide#hardware-overview) and thought I read that you have to connect the reset to ground, but that might be not true after reading it again. So i'll try doing that and see what happens.

Thanks!!
