I found the solution.
Look at this
Place the following in your Node-Sketch e.g. for Node ID 23
#define MY_NODE_ID 23
and the communication between node and Gateway is ok.
I hope this works for you.
I have exactly the same output of log. The RS485 modules I use seems to be the same ones. I use 2 Nanos. The RX/TX/Error-LEDs #defines and the Inclusion-mode #defines in the Gateway-/Node-Sketch are not commented.
How can I get more infos to solve the problem?
I also have this experience and I controlled the wiring several times. Tested several (for rs485 modified) sketches against rs485 gateway without success. To test hardware I used this examples and the communication is functioning, so hardware seems ok.
Is there anyone who can help?
