- DemoTest : full demo sketch
- Checks if the modem is available
- reads temperature, supply voltage, hardware & firmware version, power level
- sends temperature & supply voltage on Sigfox network

- sendMultipleValues : sending various values in a single message
- sendSingleValues : sending values from a single analog sensor
Like any other library, see tutorial
####Sigfox module initialization
ARM boards do not support SoftwareSerial library, but have a few hardware serial ports available. There's a single library file to include and a simple line of code to map the signals according to your device :
#include <Akeru.h>
Akeru akeru(&Serial1); // D0+D1
Port mapping :
| Serial port | RX | TX |
|---|---|---|
| Serial1 | D0 | D1 |
| Serial2 | D12 | D10 |
| Serial3 | D5 | D2 |
In order to use Serial2 & Serial3 you'll need to modify 2 files, see tutorial on our forum (in french).
####Powering up
A single line to add in your void setup() :
akeru.begin(); // returns 1 when everything went ok
####Enabling/Disabling echo
To see AT commands and their answers : akeru.echoOn();
To hide AT commands and their answers : akeru.echoOff();
####Sending data
Data is sent to the Sigfox network in hexadecimal format, and the payload has to be a String of all elements you want to send. To ensure proper conversion of your variables, you can use akeru.toHex() method :
int val = analogRead(0);
String valString = akeru.toHex(val);
akeru.sendPayload(varString);
Note that if you send a array of char you need to provide its size in order to convert it :
char array[] = "Hello world";
String arrayString= akeru.toHex(array, sizeof(array));
akeru.sendPayload(arrayString);
