We are developing a custom embedded Web Management GUI Quectel RG502Q-EU-based USB dongle.
Our current modem information is:
· Module: RG502Q-EU
· Firmware: RG501QEUAAR12A01M4G_OCPU_ZM_04.001.04.001
· USB VID/PID: 2C7C/0800
We have already developed the HTML/CSS/JavaScript frontend and REST API specification.
Please provide the following development resources:
1. QuecOpen/OpenCPU SDK compatible with our exact firmware.
2. Supported Ubuntu Linux build environment and cross-compiler.
3. SDK documentation, examples, headers and libraries.
4. HTTP server and embedded filesystem integration documentation.
5. APIs for SIM, network registration, LTE/5G signal, APN, band configuration and modem status.
6. Application packaging and installation utilities.
7. Instructions for deploying only our custom application without replacing the entire modem firmware, if supported.
8. Firmware backup, recovery and rollback procedures.
9. Documentation for configuring the USB management network and accessing the Web GUI without a SIM.
10. Security requirements for authentication, HTTPS and signed application updates.
