Library Description

The library contains basic functions for controlling the click board.

Key functions:

• int32_t sigfox3_init() - Function for initializing the sensor.
• int32_t sigfox3_wakeUp() - Function for waking up the sensor from the sleep mode.
• int32_t sigfox3_sleep() - Function for placing sigfox to the low power mode.

Example description

Click board wakes up from sleep. Some tests are performed. After the tests and after the data has been sent and received from the network the click board is placed into the sleep mode to its low power mode. All events that are executed inside of the application task are printed to the serial port.

void applicationTask()
{
 char spiFrameACK = 0;
 char rData[20];
 uint8_t sendPayload[12] = "Test msg";

 _status = sigfox3_wakeUp();
 if(_status == _SIGFOX3_STATUS_SUCCESS)
 {
 mikrobus_logWrite("Wakeup succesfull",_LOG_LINE);
 _status = sigfox3_testSpicon(&spiFrameACK);
 if(spiFrameACK == 1)
 {
 mikrobus_logWrite("SPI test finished succesfully",_LOG_LINE);
 mikrobus_logWrite("Sending data to sigfox network",_LOG_LINE);
 _status = sigfox3_receiveMessage(&sendPayload[0],&rData[0]);
 if(_status == _SIGFOX3_STATUS_SUCCESS)
 {
 mikrobus_logWrite("Data received",_LOG_LINE);
 mikrobus_logWrite(&rData[0],_LOG_LINE);
 }
 else
 {
 mikrobus_logWrite("Network error",_LOG_LINE);
 }
 }
 else
 {
 mikrobus_logWrite("Error in echo frame",_LOG_LINE);
 }
 }
 else
 {
 mikrobus_logWrite("Error in wakeup",_LOG_LINE);
 }
 _status = sigfox3_sleep();
 if(_status == _SIGFOX3_STATUS_SUCCESS)
 {
 mikrobus_logWrite("Sleep entered",_LOG_LINE);
 }
 else
 {
 mikrobus_logWrite("Error entering sleep",_LOG_LINE);
 }
 Delay_ms(5000);

}

Additional notes and information

Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
