Sigfox 04: Send string with ACK

This example shows how to send a Sigfox packet waiting for a ACK (acknowledgement) to arrive. In this example, the message to be sent is defined as a string. This string defines the diferente HEX values of the bytes to be sent

Required Materials

1 x Waspmote 1 x Battery 1 x Sigfox 868 or Sigfox 900 module 1 x 868/900 MHz antenna

Notes

- This example can be executed in Waspmote v12 and Waspmote v15
