LoRa data transmission technology imposes restrictions on the maximum packet size,
depending on the speed at which the given packet is transmitted. If the data received through
the external interface cannot be transmitted in one packet, they are split into several packets,
which are transmitted sequentially.

3. Packet with data about external power

Sent in case of change external power status on LoRaWAN port 2.
