SP1ML Firmware

AT Commands - Firmware SP1ML is provided with wireless serial cable replacement FW

UART host interface allows simple connection to an external host microcontroller

Host microcontroller GPIOs to control SP1ML (shutdown mode, switch from command to operation mode, FW upgrade)

Open Platform - Application Processor SP1ML FW could be replaced by a user application, enabling use as a wireless

application module where no external microprocessor system is required.
