Test Equipment & Pi Integration & Architecture

@Microlent

I’ve gone through your Technical_Proposal_V3.0.0, and your direction makes sense. The only suggestion I’d add up front is to isolate the serial-photometer stack in its own service (systemd-supervised). This makes field recovery simpler and gives us cleaner OTA rollback paths mentioning this now so you’re aware of one intentional improvement I’d make to the approach. Here’s how I plan to handle Phase 1: • Build the Pi adapter with photometer serial integration • Expose a stable HTTP API for the Android HMI • Implement AP/offline mode for field use • Validate compatibility against your reference firmware • Deliver a repeatable Pi image + flash-ready field-trial package For Phase 2, I’ll produce a clear architecture blueprint covering all interfaces, security model, OTA/rollback, and remote-serviceability. I can start as soon as hardware arrives. Let me know when to sync on milestones. Best, Jenifer

Hello, I understand that you need a Raspberry Pi edge adapter for your project that involves photometer integration and system architecture. My approach will be to create a solid integration of the photometer using serial communication and set up an HTTP API for your Android interface. I will ensure that the system supports offline mode for field use and is verified against your reference firmware. The code will be packaged as a repeatable Pi image for easy deployment. For the Phase 2 blueprint, I will outline the entire system architecture, including all interfaces and their security models, while also defining a reliable OTA/update and recovery strategy for your units in remote locations. What specific features do you want the HTTP API to support? Do you have any preferred testing methods or tools for integration? What’s the expected timeline for field testing after the API is developed? Can you provide details on the hardware you can supply immediately? Is there a specific Raspberry Pi model you prefer for this project? What level of security are you looking for in the interface designs? How often do you anticipate needing to update the units in the field? What are your success criteria for each milestone? Are there any specific challenges you anticipate during integration? Thanks,

@jmvdesignsohio

Hi, I have strong experience building Raspberry Pi edge adapters, serial integrations and secure API bridges for lab and industrial equipment. I can deliver your Pi based photometer adapter exactly as defined in Technical Proposal V3 with clean Python services, serial protocol handling, an offline access point mode, and a stable HTTP API for the Android HMI. I have built similar hardware to software bridges where a Pi manages field operations, validates firmware compatibility and exposes a structured REST layer. You will receive a reproducible Pi image plus a field trial package ready for flashing and shipment. In parallel I will prepare the complete Phase Two architecture defining every interface, security layer, OTA and recovery strategy for long term maintainability. My deliverables include documented code, reproducible builds and integration testing with your reference photometer. Once you ship hardware we can begin serial integration and API development immediately. Best regards, Joseph

@makotok5

♦️ Hello! Hope this helps! Do you need a Raspberry Pi edge adapter that talks cleanly to your photometer over serial, serves an Android HMI via HTTP, and still works offline in AP mode? I’ve reviewed your spec and can deliver repeatable Pi images that include serial integration, API endpoints, and firmware-compatibility checks. Your project requires robust edge integration and clear future architecture, both of which I’ve solved using Python, RESTful APIs, and structured embedded docs. I can also produce a Phase 2 blueprint detailing system architecture, interfaces, security model, and OTA/recovery strategy for remote units. Let’s discuss the details of the goals. Best regards.
