Development Scope
Scope and Basic Check
Determine the existing foundation, technical dependencies and content that needs to be developed based on MCU and board, RTOS, module firmware, UART/USB, memory and task cycle.
Implementation and integration
Split acquisition, communication, storage and control tasks and develop AT adaptation or host protocol stacks, asynchronous messages, connection state machines and fault recovery.
Delivery Documentation
Deliver firmware source code and build instructions.
Verification and Constraints
Peripheral and memory conditions will limit concurrent tasks, TLS, and cache size, and should be confirmed on the target board rather than a simulation environment.
Project implementation process
Verification of data and interfaces → Confirmation of technical solutions and verification use cases → Implementation of integration with the target environment → Regression of abnormal scenarios → Transfer of version data.
Verify the implementation results in the target hardware and software environment, and deliver records of associated interface configurations, version dependencies, and problem handling to facilitate subsequent integration and maintenance by the enterprise R&D team.
Project Inputs
- MCU and board, RTOS, module firmware, UART/USB, memory and task cycle.
- Design information, code, interface permissions and target test equipment can be provided.
- Source files, programs or tools expected to be delivered, inter-module integration testing responsibilities and project nodes.
- Acceptance samples, environment, test conditions and passing thresholds.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| achieve results | Deliver firmware source code and build instructions. | Test asynchronous reporting and command responses interleaved. |
| Integrated data | Versions and dependencies, interface configuration, usage or deployment steps, and integration changes | Verify buffer overflows, task timeouts, and watchdogs. |
| Verify records | Test conditions, execution records, problem lists and regression results | Data integrity when recording acquisition and communication in parallel. |
The delivery scope and acceptance criteria are determined based on the target environment. Third-party SDK, licenses, laboratories, cloud resources, equipment materials and on-site support are listed separately; when the existing information is insufficient, follow-up work will be determined through interface verification or key function verification.
Frequently Asked Questions
How to troubleshoot AT commands that occasionally time out?+
At the same time, record the serial port raw data, command timing, asynchronous events and power status, distinguish module unresponsiveness, parsing misalignment, task blocking and network timeout, and then determine correction and regression use cases.
STM32／RTOS 4G What information is required for network firmware development?+
Please give priority to providing MCU and board, RTOS, module firmware, UART/USB, memory and task cycle. At the same time, the existing implementation, problems encountered, expected changes, and compatible test conditions are explained to facilitate the determination of implementation scope and reproduction methods.
Can it be implemented on existing products?+
You can first evaluate the scope of existing designs and versions that can be changed, retain the verified parts, and determine the interfaces and dependencies that need to be adjusted. This service requires attention: peripheral and memory conditions will limit concurrent tasks, TLS and cache size, and should be confirmed on the target board rather than the simulation environment. Existing and new functions must undergo regression testing within the agreed scope after the changes.
