hi, yes it was very simple :-D the gateway has worked fine in this time, i thought that when nothing shown in serial monitor that the gateway dont work, but it did it, after i connected the gateway to FHEM (my controller) i saw that FHEM connects t mys Gateway.
So it worked all the time

Have you tried to enable the debug output in the GatewayW5100 example? I think it is disabled by default, due to the limited memory on the small atmega 328p

alexsh1

@tbowmo

Yes, I did

// Enable debug prints to serial monitor
#define MY_DEBUG
#define MY_DEBUG_VERBOSE_SIGNING

alexsh1

I am running Arduino IDE 1.8.1 on Windows 10
Arduino AVR 1.6.18
Arduino SAMD 1.6.12
MySensors SAMD 1.0.5

EDIT: I have tried to upload the default sketch on macbook with Arduino IDE 1.6.2
It is still the same - no debug info in the terminal

alexsh1

OK, I did manage to get debug working partially.
The gateway reads messages, but does not work as the gateway

I never had a message:

EDIT: Self-test with SensebenderSerial sketch gives me this:

@alexsh1

Could you check the soldering of the samd?

SD card fails, if you haven't inserted a card, when running the self test.

alexsh1

@tbowmo

I do not have the SD card so that's fine

The samd looks fine - no bridges etc
I can try to re-solder it with a hot fan
Do you think samd may be at fault even though the serial GW is working?

Unfortunately, I do not have another Ethernet w5100 to try it. Probably have to order a new one

tbowmo

@alexsh1

I know that @Anticimex had problems with one of the pre-production samples that we got from China, with various problems, that was solved with "reflowing" the samd with a hot air gun.. So it was just a thought, that it could be a bad solder joint..

The W5100 is using it's own dedicated SPI port, so even though that the radio works, doesn't mean that there couldn't be any solder problems around the samd pins for W5100.

We have 3 different SPI ports in use on the gateway, one for the MysX connector, one for radio / sdcard, and one for W5100..

alexsh1

@tbowmo I do not have the oven to reflow the whole board, but can mount / unmount or re-work certain components 0805 or 0603. Below this it is a pain in the a***

Another observation - The GW behaves like this with or without W5100 mounted.
Seems like an SPI problem to me. How can I wire W5100 to MYSX please and what shall I can in the sketch please? Thank for your help - very much appreciate it

Anticimex

@alexsh1 The ATSHA is not connected to the SPI and is totally unrelated, so I am also inclined to suspect that perhaps one side of the SAMD is not entirely in contact with the pads. I had to hot-airgun mine to get USB working well but it was an early prototype like @tbowmo said.

alexsh1

@tbowmo OK, I manage to find the answer here -

MYSX
D11 - MOSI
D12 - MISO
D13 - SCK
D14 -CS

#define MY_SOFTSPI
#define MY_SOFT_SPI_SCK_PIN 13
#define MY_SOFT_SPI_MISO_PIN 12
#define MY_SOFT_SPI_MOSI_PIN 11
MY_RF24_CS_PIN 14
RF24_CE_PIN ???

Am I correct?

alexsh1

My current config for nrf24l01+ and w5100 is as follows:

#define MY_GATEWAY_W5100

#if !defined(MY_W5100_SPI_EN) && !defined(ARDUINO_ARCH_SAMD)
#define MY_SOFTSPI
#define MY_SOFT_SPI_SCK_PIN 14
#define MY_SOFT_SPI_MISO_PIN 16
#define MY_SOFT_SPI_MOSI_PIN 15
#endif

#define MY_RF24_CE_PIN 5
#define MY_RF24_CS_PIN 6

Why CE / CS pins are 5 and 6?
Should that be 27 and 3?

alexsh1

@tbowmo I have just re-worked SAMD and all the connectors (nrf24l01+ and NET_SPI), but still have the same issue sadly.

EDIT: If I change to rfm69, the same behavior is observed. It seems that Net_SPI is just not working.

tbowmo

@alexsh1

Configuration of the pins are handled by the hardware configuration file, https://github.com/mysensors/ArduinoHwSAMD/blob/master/variants/mysensors_gw/variant.h#L227

If you look in the gatewayW5100 sketch, the settings for CE / CS pins are enclosed in ifdefs, so they are only used if they are not defined previously.

If you want to connect the W5100 to the mysx connector, you can change line 174 in the hardware definition file, use SPI2 instead of SPI1 for SPI_ETH

It could also be a defective W5100 shield? Can you verify that it works on other hardware?

alexsh1

@tbowmo Swapping SPIs did not resolve the problem. I am now getting another W5100 to test further.

alexsh1

Unfortunately, a new W5100 shield did not work - it seems like a production issue with this sensebender gatewsay as the SPI2 did not work either with W5100.
Will get a new one ordered.

tbowmo

Is it possible for you to check the spi wires with a scope? Just to make sure if mosi/miso/ce/Ss lines are toggling as expected?

tbowmo

Another thing, are you using static ip? If yes, can you ping it? If no, does your DHCP server hand out an ip address?

Have you tried the basic ethernet examples for the W5100?

alexsh1

@tbowmo I am using the static IP and I can ping it, but the "Gateway Ready" message never comes up. Also I can only see the neg24l01+ log (incoming messages only)

tbowmo

@alexsh1

If you can ping it, then the W5100 is configured. Something else is wrong..

One thing that comes to mind, if you compile it as an ethernet GW, then it does not wait for serial console to be active, before initializing the radio. If you compile it as serial GW, then it waits with initialization, until serial is active.

This means that you probably is missing the GW ready message on the serial port, as it is "sent" before you have an active serial connection.

Look in MyHwSamd.cpp in the HwInit routine, remove the #ifdef around the while() loop, and try again.
