Can't compile serial gateway example, MySigningNone.h not found

[billgoolsby]

I'm a newbie at MySensors; haven't yet got a gateway or node running. I bought a SenseBender gateway board and want get it working. I'm trying to compile the serial gateway example found at https://codebender.cc/sketch:47514#SerialGateway.ino. I chose this file because it seems to have complete working code for a gateway, as opposed to MySensors\examples\GatewaySerial\GatewaySerial.ino, in which setup(), presentation() and loop() are all empty, therefore I figure it isn't a complete example and won't do anything, and being a newbie I don't know how to fill in those parts.

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 *******************************
 *
 * DESCRIPTION
 * The ArduinoGateway prints data received from sensors on the serial link. 
 * The gateway accepts input on seral which will be sent out on radio network.
 *
 * The GW code is designed for Arduino Nano 328p / 16MHz
 *
 * Wire connections (OPTIONAL):
 * - Inclusion button should be connected between digital pin 3 and GND  
 * - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
 *
 * LEDs (OPTIONAL):
 * - To use the feature, uncomment WITH_LEDS_BLINKING in MyConfig.h
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error 
 *

I did a complete fresh install of Arduino 1.8.3, then used library manager to install MySensors 2.1.1. I see that Arduino put the library in My Documents\Arduino\libraries, with all the .h and .cpp files in \cores.

When I try to compile, I get MySigningNone.h not found. I found it on the web and put it in \cores, but that didn't help - still not found. If I comment out MySigningNone.h, other of the .h files are found either, e.g. MyTransportRFM69.h.

So, I don't understand why the files aren't found if I put them in \cores. Where should they go? Why aren't they included in the distribution?

Does anyone have an example of complete code for a simple working serial gateway and a simple node? I'd like to first try a node that has a temp & humidity sensor on it.
I admit I'm finding it frustrating to get started with MySensors, though I think it will be great once I get it working.

Hi Bill,

Welcome to MySensors!

Instead of using the library manager, you could try to copy the complete MySensors folder to Arduino\libraries. (don't forget to restart the Arduino IDE afterwards)

The MySensors folder also contains an examples folder that contains different codes for gateway and sensor nodes that you should be able to compile without any problems.

@billgoolsby you are trying to compile a MySensors 1.x sketch with MySensors 2. That won't work. Follow the instructions on https://www.mysensors.org/hardware/sensebender-gateway instead.

[billgoolsby]

SensebenderGatewaySerial.ino has empty functions for setup(), presentation() and loop(). How can it possibly work with no code in these?

[mfalkvidd]

@billgoolsby because the MySensors library does what it is supposed to do

Why would we ask you to use broken code?

[billgoolsby]

So the library is entirely interrupt-driven? Is there a document describing the library's architecture and design intent?

[mfalkvidd]

@billgoolsby the gateway could probably be called event-driven but that's not why there is no need for additional code.

The concepts are described in the getting started guide, which starts at https://www.mysensors.org/about
