Connexa leverages Particle's industry standard cellular connectivity to make sure your system is always on line. Multi-carrier sims will connect to the nearest cell provider, and communications are secured at every level: RSA 1024 bit key pairs at the hardware, CoAP messaging using DTLS over UDP, and APIs with TLS security and Oauth2 credentials. Access to your device is fully managed and airtight so you don't have to juggle cellular bills or multiple software contracts. Our network of trusted software and hardware providers are here to bridge your product or service directly to the cloud. Even if you have an existing network topology, we can integrate back-up units to help you reconfigure or reboot your main communications in the event of an emergency.
