FAQ
What hardware do you support for RS-485 apps?
I support any RS-485 hardware including vending machine boards, lock systems, sensors, and custom modules, as long as documentation or SDK is provided.
Do I need to send you the physical hardware?
Not always. If the device outputs logs or a simulator is available, remote integration is possible. For full testing, physical access may be required.
Can you work with my existing protocol or command set?
Yes. I can implement your custom commands (RUN, ACK, SCAN, TEMP, LOCK/UNLOCK, etc.) as long as you provide the protocol documentation.
Do you integrate .jar or .so SDK files?
Yes. I handle full SDK integration including NDK/JNI support and Android serial communication libraries.
Can you build the full Android app UI along with RS-485 integration?
Yes. Premium package includes UI, device control panel, logs, real-time monitoring, and full app development.
What if I only need help debugging or testing RS-485 communication?
The Basic package covers RS-485 testing, analyzing logs, fixing communication issues, and implementing initial commands.
Can you add cloud connection or API integration?
Yes. I can connect your hardware data to cloud platforms like Firebase, AWS, or a custom backend.
Do you support Modbus RTU?
Yes. I can integrate both custom RS-485 protocols and Modbus RTU communication.
Will the app work offline with hardware?
Yes. RS-485 hardware communication is fully offline unless you request online sync.
Is my project information confidential?
Absolutely. All your hardware, SDK, and documentation remain 100% confidential.
