Lightweight Cellular AT parser
LwCELL is lightweight, platform independent, cellular modem AT commands parser, targeting (as of today) communicion with SIMCOM based modules SIM800/SIM900 or SIM70xx.
Module is written in C11 and is independent from used platform. Its main targets are embedded system devices like ARM Cortex-M, AVR, PIC and others, but can easily work under Windows, Linux or MAC environments.
Features
- Supports
SIM800/SIM900 (2G) and SIM7000/SIM7020 (NB-Iot LTE) modules
- Platform independent and very easy to port
- Development of library under Win32 platform
- Provided examples for ARM Cortex-M or Win32 platforms
- Written in C language (C11)
- Allows different configurations to optimize user requirements
- Supports implementation with operating systems with advanced inter-thread communications
- Currently only OS mode is supported
- 2 different threads handling user data and received data
- First (producer) thread (collects user commands from user threads and starts the command processing)
- Second (process) thread reads the data from GSM device and does the job accordingly
- Allows sequential API for connections in client and server mode
- Includes several applications built on top of library:
- MQTT client for MQTT connection
- User friendly MIT license
