To change the transmission periodicity of a transmitter, a new configuration downlink must be sent to it from the Sigfox backend.
⚠ Using Sigfox, configuration messages can only be received at power up of the transmitter. To change the transmission periodicity of an already installed transmitter, it is therefore imperative to disconnect its battery and configure the downlink before reconnecting the battery.
The downlinks to be sent are structured as follows:
You can then ensure that the downlink has been received by observing the behaviour of the LEDs after reconnecting the battery :
