Callback Server

Note: Sigfox and LoRaWAN radios unique ID must be known previously to use the web form. There are several

ways those unique ID are provided. Additionally the Libelium Smart Devices App can be used to read those ID

All Smart Parking nodes will synchronize date and time with the server (NTP recommended as commented

previously in this chapter) in any case, no matter that a valid binary value has not been previously stored for the

radio ID.

• Response to the Start Frame number 1, transmitted by the node in the activation process. This response

frame allows the initial time synchronization of the internal clock. In normal conditions, the activation process

happens only once.

• Response to the Daily Update Frame with a timestamp, in order to perform a time synchronization of the

internal clock. This will happen once per day and helps to keep the node’s time drift to minimum.
