UNO W5100 Shield not pinging.

[doctor64]

Are you update IP and MAC addresses in sketch? I use W5100 (with little modifications for DHCP support) in MQTT gateway without any problems.

[MatrixIII]

Yes, the IP address is changed in both mysensors sketch and example webserver sketch. I have not changed the MAC address. I can ping the ip on the example webserver sketch but not in the mysensors Ethernet sketch.

@MatrixIII Do you set #define SOFTSPI in libraries\MySensors\utility\RF24_config.h ? It's only thing what i can think about.

[MatrixIII]

Yup, that and the Ethernet.h uncommenting change in the main sketch. Unfortunately, I have read the documentation 10 times in hopes to catch something that I may have missed but can't figure this one out.

[MatrixIII]

I figured this out. In the sketch it was getting stuck on the following line since writeEthernet is a callback and was getting called but is not initialized yet.

gw.begin(RF24_PA_LEVEL_GW, RF24_CHANNEL, RF24_DATARATE, writeEthernet);

I switched the order to initialize the Ethernet shield first and it works like a charm now

Ethernet.begin(mac, myIp);

// give the Ethernet interface a second to initialize
delay(1000);

// Initialize gateway at maximum PA level, channel 70 and callback for write operations 
gw.begin(RF24_PA_LEVEL_GW, RF24_CHANNEL, RF24_DATARATE, writeEthernet);

@MatrixIII thank you so much for sharing this solution!!! You may have seen my posts a couple months or so ago, and I just couldn't get this to work, but after making the change that you did, it seems to be working. thanks!

This saved my day too! Thanks!
I wonder why this is not already changed in the example EthernetGateway.ino..

Missed this one. The change has been pushed to github now.

It's easer if you provide a github pull request when you find this type of problems.

Thanks MatrixIII, I was just about to give up on my Ethernet-gateway when I found this thread, you saved my day too! :satisfied:
I just downloaded the Ethernet-gatewaysketch from mysensors, isn't this problem supposed to be solved or did I download from wrong place?
