Based on the Nordic nRF9160 LTE-M/NB-IoT SIP and the Nordic nRF52840, FCC, Verizon, and AT&T certified1, SigCell BLE USB is designed for intelligent IoT applications with the capability of interfacing to host systems via the USB interface. The USB interface enumerates as two UARTs. The host can use the first UART to control the cellular connection via AT commands or Signetik’s API. Signetik’s API supports various IoT protocols such as HTTP REST, CoAP/CBOR, MQTT, TLS, and more. The second UART is used with an HCI interface that is recognizable by most operating systems, out of the box.
More than just a modem! The intelligence built in makes integration quick and easy, while allowing complete customization.
