5.3.4 Activation
Module activation
Upon delivery, CMi4130 is set to passive mode, which means no messages will be transmitted from the
module. The module can be activated in one of the following ways:
a) By using the module push button:
Press down the push button of the module for at least five
seconds until the green LED lights up.
b)
By using the Elvaco OTC App:
Open the Elvaco OTC app (downloadable via Google Play) and
scan the module (make sure NFC is activated on the phone). Remove the front enclosure of the
meter if needed. Go to
Apply mode
, set the Power mode to “active” and click
Apply settings
.
Place the phone next to the module. New settings are applied via NFC. You can make sure that
the module has joined the LoRaWAN network correctly by checking the “network join” field in the
Inspect tab of the OTC App.
Network join
When activated, CMi4130 will attempt to join the LoRaWAN network. The phase is indicated by short
flash on red light, then green and red LED lights up for 1 second, followed by short flashes on the green
LED until the module has joined the LoRaWAN network. When CMi4130 succeeds in joining the
LoRaWAN network, the green LED will light up for 8 seconds, as illustrated by
Fel! Hittar inte r
eferenskälla.

If the module fails to join the LoRaWAN network, it will perform retries until it succeeds. The time between
each attempt will increase for every attempt until it is performed once every day. A new join attempt cycle
can be manually started anytime by using the push button to reboot the module or by deactivating and
activating the module using the Elvaco OTC App.
When the module has joined the LoRaWAN network, it will perform three quick transmissions (regardless
of transmit interval settings) before starting to use its configured transmit interval settings. By using the
Elvaco OTC App, you can easily verify that the module is successfully communicating with the meter
(“Meter communication”) and is connected to the LoRaWAN network (“Network joined”).
Soft start
In rare cases, if the battery is weak, the module will perform a soft start to be able to start-up despite the
condition of the battery. The soft start takes 10 minutes to complete. The red LED will blink shortly every
10
th
second until the start-up has completed.
