IoT activity is embedded in today’s application. Almost every device uses some type of communication, from WiFi, BLE, Sub-GHz or NB-IoT/LTE/2G/3G.
LwCELL has been developed to allow customers to:
Develop on single (host MCU) architecture at the same time and do not care about device arch
Shorten time to market
Customers using LwCELL do not need to take care about proper command for specific task, they can call API functions to execute the task. Library will take the necessary steps in order to send right command to device via low-level driver (usually UART) and process incoming response from device before it will notify application layer if it was successfuly or not.
GSM device runs official AT firmware, provided by device vendor
Host MCU runs custom application, together with LwCELL library
Host MCU communicates with GSM device with UART or similar interface.
