NB-IoT 25: Sleep modes
This example shows how to use HTTPS 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 NB-IoT / Cat-M module 2 x NB-IoT / Cat-M antenna 1 x SIM card
Notes
- The battery has to be connected. - This example can be executed in Waspmote v15
Code
/*
* ------ NB_IoT 25 - sleep modes --------
*
* sending HTTP GET and activating Sleep NB-IoT module mode (PSM)
*
* Explanation: This example shows how to use HTTPS requests to send
Waspmote frames from Waspmote to Meshlium. Therefore, the Meshlium
will be able to parse the sensor data and insert it into the database
