💬 Sensebender Gateway

[alexsh1]

@tbowmo Do you think softSPI is at fault? What pins shall I use? I tried these

#define MY_SOFTSPI
#define MY_SOFT_SPI_SCK_PIN 24 //13 //23  //14
#define MY_SOFT_SPI_MISO_PIN 22 //14 //22 //16
#define MY_SOFT_SPI_MOSI_PIN 23 //12 //21 //15

[alexsh1]

@tbowmo I cannot ping it though if I load MySensors GW sketch -
Destination host unreachable.

[alexsh1]

@tbowmo I have just discovered that the second Ethernet module I have is not W5100 but ENC28J60. Not sure if it is supported by sensebender GW (probably using native Arduino ethernet library?).
So this module is now being returned and just to figure out any hardware issue I need to order a new W5100

[tbowmo]

You should not use soft spi, as there is separate hardware spi ports for radio and W5100.

If you load the default GatewayW5100 example sketch, then it should work out if the box. Perhaps you need to enable rfm69 instead of nrf24 at the top of the file, but that should be all that is needed.. To get a gateway up and running with W5100

[tbowmo]

@alexsh1

OK, just to recap here, you have a gateway, and a W5100. If you use that combo, and the http server example, you can ping the gateway, and Load the html files in a browser, right?

If you load stock GatewayW5100 mysensors example sketch, then does that work? (no need to redefine pins for hardware etc, that is handled by the target hardware profile, you choose in arduino)

[alexsh1]

@tbowmo I must admit I have not tried to load files in the browser when trying Ethernet sketch. Only pinging
Yes, you are correct - gateway, nrf24l01+ and w5100

[tbowmo]

@alexsh1

So gateway with nrf and W5100 is working as it should as an ethernet gateway? Then the W5100 is working with the gateway.

What is the hardware configuration that you can't get to work? Rfm69 and W5100? Together with the samd GW?

(just trying to figure out what is going on :))

[alexsh1]

@tbowmo No, sensebender GW is working with nrf24l01+ as a serial GW, but not with W5100 as ethernet GW.

Interesting observation - I cannot ping the IP any more if I load the ethernet sketch. For your understanding the sensebender GW was never working with W5100 with either nrf or rfm69. Something going wrong around W5100.

I'll hook up W5100 shield to Arduino nano to test it - I have a suspicion about it. However, even without W5100 connected, sensebender GW is showing IP as 0.0.0.0 (I set IP 10.1.1.150). Why?

[tbowmo]

If the ethernet library can't initialize the W5100, it will just write IP address as 0.0.0.0.

Can you please turn on verbose compile logging in arduino? (file -> Settings, set a checkmark at show verbose output during compilation, and choose "all" in Compiler warnings)

I just want to make sure that it is using the correct ethernet library.

[alexsh1]

@tbowmo I have verbose on already.
I think you hit the nail on the head:

[tbowmo]

It is using "our" ethernet driver, which it should be.. The default arduino ethernet driver is hardwired to SERCOM0 for SPI, while we have it on SERCOM1.

I'll try to bring up one of my own gateways with W5100 later today.

@alexsh1

Below is the startup log from my Gateway with W5100 and RFM69 attached:

As seen, the W5100 is initialized with ip address,

Telnet to the Gateway is also working:

The above is with the stock example sketch from mysensors (right now latest development branch though). The only things I changed, was to enable RFM69, instead of NRF24, and set a different IP address, to match my network settings.

Everything else is running as is, delivered from the mysensors examples..

[alexsh1]

@tbowmo if you take off the W5100 shield, does it still come up with IP please:

[alexsh1]

@tbowmo Thanks - I am assuming that I have a faulty W5100 shield in this case. Unfortunately, I have received a wrong replacement shield enc28j60 instead of W5100. Do you know if Sensebender GW would work with

#define MY_GATEWAY_ENC28J60

The one I have does not have AMS1117-3.3 on board and must be fed with 3.3V instead of 5v

[alexsh1]

@tbowmo The problem has been identified. I have used a hot fan to re-sit W5100 on the network shield.

Still cannot ping it, which means there is still a problem with the shield.
It is of a poor quality and does have multiple bridges around W5100 like this:

I found a similar problem here:
https://electronics.stackexchange.com/questions/156147/are-solder-bridges-on-chips-always-bad

At least I know where the problem is.
Thanks @tbowmo

[tbowmo]

@alexsh1

Great, that we found the problem, and thanks for reporting back here on the forum :)

I haven't tried with other ethernet controllers, than the W5100, And the socket for W5100 is supplied with 5V directly.

Also, I do not know if they are pin compatible?

[alexsh1]

@tbowmo I think they are pin compatible but unfortunately take different voltage. On arduino board, somebody told me that enc28j60 can tolerate 5V. It seems to be the case, as mine survived w5100 socket

EDIT: From the enc28j60 datasheet

• Operating Voltage of 3.1V to 3.6V (3.3V typical)
• 5V Tolerant Input

[alexsh1]

@tbowmo I can confirm now that everything is working fine after I tested the Sensebender GW with the third (yes, third!!!) shield. Thanks Thomas for your help!

[alexsh1]

@tbowmo The pinout is identical.

W5100

ENC28J60

I can modify ENC28J60 shield (reduce voltage to 3.3V) and test it with the sensebender GW, but it does require hardware mod
