4G 08a: Send to Meshlium (HTTP)

This example shows how to use HTTP requests to send Waspmote frames from Waspmote to Meshlium. Therefore, the Meshlium will be able to parse the sensor data and inset it into the database

Required Materials

1 x Waspmote 1 x Battery 1 x 4G module 1 x 4G antenna 1 x SIM card

Notes

- The battery has to be connected. - This example can be executed in Waspmote v15

Code

/*
    --------------- 4G_08 - Send frames to Meshlium  ---------------

    Explanation: This example shows how to use HTTP requests to send
    Waspmote frames from Waspmote to Meshlium. Therefore, the Meshlium
    will be able to parse the sensor data and inset it into the database

    NOTE: This example is valid for Meshlium Manager System versions
    prior to v4.0.9 which only supports HTTPS.
