Arduino UNO ethernet gateway problem
-
Well... it depends on the source of the 3.3v, but looking at your picture you are taking power directly from arduino and that is for sure not able to supply enough power for a PA radio. Try also to set nrf24 power to MIN and start from there. If I were you I would use an adapter with voltage regulator from 5v to 3.3v that would make like easier. If you are going to add capacitor, put it as close as possible to radio module (you could solder on the other side of the pins.

Hi!
I'm just starting my Mysensors journey with building an ethernet gateway based on Arduino UNO.
Parts I'm using:
- Arduino UNO from somewhere on Aliexpress (link does not work anymore)
- UNO ethernet shield from here: https://www.aliexpress.com/item/UNO-Shield-Ethernet-Shield-W5100-R3-Development-board-FOR-arduino/32341820750.html?spm=2114.13010608.0.0.lpQQAC
- NRF24L-module from here: https://www.aliexpress.com/item/1sets-Special-promotions-1100-meter-long-distance-NRF24L01-PA-LNA-wireless-modules-with-antenna/32341792715.html?spm=2114.13010608.0.0.lpQQAC
I connected the RF-module how described here: https://www.mysensors.org/build/ethernet_gateway
A2 - MISO
A1 - MOSI
A0 - SCK
6 - SCN
5 - CE
I uploaded the W5100 Gateway scetch and the device seems to be in a endless boot loop.
Here's what I see in the serial monitor of Arduino IDE:

Hi!
I commented the line #define MY_W5100_SPI_EN 4 and wired the module as described in the post linked.
I also added this line: #define MY_RF24_PA_LEVEL RF24_PA_MIN to lower the power need.Tried to add this adapter board: https://www.aliexpress.com/item/New-Socket-Adapter-plate-Board-for-8Pin-NRF24L01-Wireless-Transceive-module-51/32655936568.html?spm=2114.13010608.0.0.WnqXqC
Now this is what I'm getting with DHCP configuration:
0;255;3;0;9;MCO:BGN:INIT GW,CP=RNNGA--,VER=2.1.1 0;255;3;0;9;TSM:INIT 0;255;3;0;9;TSF:WUR:MS=0 0;255;3;0;9;TSM:INIT:TSP OK 0;255;3;0;9;TSM:INIT:GW MODE 0;255;3;0;9;TSM:READY:ID=0,PAR=0,DIS=0 0;255;3;0;9;MCO:REG:NOT NEEDED DHCP FAILURE...0;255;3;0;9;!MCO:BGN:TSP FAILAnd with static IP:
IP: 192.168.10.25 0;255;3;0;9;MCO:BGN:STP 0;255;3;0;9;MCO:BGN:INIT OK,TSP=1Btw my versions used:
- macOS 10.12.3
- Arduino IDE 1.8.2
- Arduino AVR Boards 1.6.18
- MySensors library 2.1.1
Still the board is somehow looping and does not appear to the network.

Yes it is and even the link lights wont light up on my switch. I'll try to add the capasitor tomorrow. I'll also try this with a regular radio module (without the antenna)

Hi!
Investigating this issue it seems that my chinese ethernet shield has the wrong kind of terminating resistors on the ethernet line as described here.
So first I'll try to apply the common fix for that problem (change the resistors) and then I'll get back to you.Btw thanks for the awesome support!

Hi!
Sure. Here is the link: https://forum.arduino.cc/index.php?topic=351477.15
There are many options for the fix but the easiest is defined by klggi on page2 (just solder 2 100ohm resistors on the backside of the ethernet connector).
I'll try to apply this fix tomorrow evening, I'll get back to you on how it went. -
@Misna Added the 2 100Ohms resistors and it seems it is working. Maybe I could order some more shields and complain again they are faulty and have them refunded and do this quick repair :D
At least it would be a little revenge on the many hours I lost with this faulty shield
