There are two different communication protocols for e-scooters: TCP/IP and MQTT. Both communication protocols are compatible with Scootable. MQTT is defined as Message Queueing Telemetry Transport and is an OASIS standard publish-subscribe network protocol for the Internet of Things (IoT). It transports messages between the scooters and the server. It is designed as an extremely lightweight communication protocol which is ideal for connecting remote devices with minimal network bandwidth. TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP is also used as a communications protocol in the private scooter network. Both protocols are suitable for Scootable. However MQTT is a more reliable and secure protocol for IoT systems. We recommend you to prefere scooters with IoTs which have MQTT abilities.
