[SOLVED] Problems with Ethernet Gateway (Arduino Ethernet Shield)

[BulldogLowell]

Will do... I am thinking that the power requirement for the antenna version may be more than my poor Uno can deliver...

[hek]

Yes, most probably.

[Dan S.]

Might want to check:http://forum.mysensors.org/topic/466/ethernet-gateway-problem.
I had the same problem but after addressing SPIO and radio problems it's been rock steady over a week now. Had to use separate power supply for the antenna version.

[Dan S.]

Oh, and make sure you use 1.4.1 library.

[BulldogLowell]

@Dan-S.

Thanks, I didn't see any announcement re: 1.4.1, but it seems a few of the library files were indeed updated.

I'm gong to mess about with the lower power radio, but can you tell me how you powered your radio?

Also, what sketch did you end up with for the gateway with software SPI?

THANKS!!

[Dan S.]

I used a standard (cell phone type) 5V power supply and with the AMS1117 (listed in hardware) to knock it down to the 3.3V required by the radio. If your gateway (or sensor) works for a while and then stops and then will start again when plugged back in/rebooted you can almost bet it's a radio power problem (if you are already using soft SPI for your gateway).

Use the latest sketch from the 1.4.1 library for the gateway. The soft SPI stuff is included in the latest library. I just needs to be turned on by some include statement changes in the gateway and RF24_config.h. It requires changes in the radio wiring to the arduino also. I used the instructions provided by Anticimex that are contained in the link I posted above. It's a long thread but the instructions are in there. Probably needs to be broken out as a separate how to posting.

Yeah,

The thread is so long, and after reading through it a few times, it is not possible for me to understand what I need to do to get this working.

I am using the latest library with the Ethernet Gateway sketch on github... but still not working

Here is a photo of my rig, separating the power supply for the radio.

I agree with @BulldogLowell . The description that @Anticimex did in the other thread is not easy to understand, at least I could not either. A write-up from someone that has actually done it would be greatly appreciated.

@korttoma what is unclear?

[niccodemi]

@korttoma

exit Arduino ide, download latest Master library 1.4.1

Patch file RF24_config.h (xxxx\MySensors\utility) to enable softspi,

uncomment (remove //) #define SOFTSPI

and change pin numbers as below:

const uint8_t SOFT_SPI_MISO_PIN = 15;
const uint8_t SOFT_SPI_MOSI_PIN = 14;
const uint8_t SOFT_SPI_SCK_PIN = 16;

Connecto radio and gateway as per instructions for ethernet gateway except MISO, MOSI and SCK.
These connect as below
radio MOSI to arduino A0,
radio MISO to arduino A1,
radio SCK to arduino A2.

start arudino ide 1.5.8, open Ethernet Gateway sketch and amend/add below lines

add this line: #include <DigitalIO.h>

comment UIPEthernet.h (//#include <UIPEthernet.h>)

uncomment Ethernet.h (#include <Ethernet.h>)

and choose IP address

[Dan S.]

@niccodemi Very good description of what needs to be done. Only addition I would make is that you have to undo the changes you made other than to the gateway sketch when you go back to creating sensors. May be just as easy to reload the library to do that.

[Dan S.]

@BulldogLowell You are not using the antenna version but since I am, I used an entirely separate 5 volt wall wart supply to power the radio through the AMS117--did not go through the UNO power as it looks like you did in the pix. Just need to make sure that all the grounds are common if you do like I did, i.e. connect the ground from the separate supply to the UNO/shield ground in addition to the AMS117 and radio ground.

const uint8_t SOFT_SPI_MISO_PIN = 15;
const uint8_t SOFT_SPI_MOSI_PIN = 14;
const uint8_t SOFT_SPI_SCK_PIN = 16;

and these are the correct pinouts for my Arduino Ethernet Shield, correct?

This is moving the SPI communication between the Uno and the shield off to another set of pins, and we are leaving the radio pins on hardware SPI?

Thanks!!!!

[BulldogLowell]

@Dan-S.

Apart from my question above, my only concern is how much power. It occurs to me that the radios attached to my sensor nodes NEVER have this problem, so it make me think that he Ethernet Shield consumes too much power... we got that. Is it the consensus that the power that Uno can provide is not enough to power the Radio and the Ethernet shield?

Thanks for the assistance, it is appreciated. Hope to get there soon!

[Dan S.]

@BulldogLowell Once you sent the pin definitions in RF24_config.h as you indicated you connect the MOSI, MISO and SCK pins of the radio to A0,A1 and A2 on the Ethernet shield/UNO as niccodemi indicated. The other radio pins remain connected as they were originally.

[BulldogLowell]

right, completely understood now. i updated my IDE, made all the edits, changed the pins and loaded up my rig.

fingers crossed.

Thanks for everyone's help!

@BulldogLowell

OK... Working fine :)

THANKS to everyone who assisted!!!

UPDATE: 12 hours and working perfectly!

[korttoma]

Thanks @niccodemi for the detailed how to. Now to only thing unclear to me is if this can be applied on the Ethernet board I have or should I order a new one? I have built a Ethernet GW with a Pro mini and that Ethernet board but I just have not found time to take it in to use and then there was all this about the SPI issue that made me push the task ahead of me.

[niccodemi]

@korttoma , I don't see why it shouldn't work with your board. It doesn't cost you anything to try and report back here how it went.
