Development Scope
Scope and Basic Check
Determine the existing foundation, technical dependencies and content that needs to be developed based on hardware power supply control, module sleep mode, wake-up source, sampling upload cycle, battery and target operating conditions.
Implementation and integration
Establish a complete power consumption state machine to coordinate sensor power-on, sampling, caching, connection, uploading and sleep, and limit retry consumption under abnormal networks.
Delivery Documentation
Deliver firmware, power profiles and test cases.
Verification and Constraints
The availability of sleep mode depends on the module, firmware, main controller and network conditions; you cannot promise battery life by just modifying one parameter.
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
- Hardware power supply control, module sleep mode, wake-up source, sampling upload cycle, battery and target operating conditions.
- 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, power profiles and test cases. | Measure current and time state by state. |
| Integrated data | Versions and dependencies, interface configuration, usage or deployment steps, and integration changes | Verify wake event and missed wake handling. |
| Verify records | Test conditions, execution records, problem lists and regression results | Test scenarios with no network, low battery and frequent events. |
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
Does reducing upload frequency necessarily reduce total power consumption?+
Typically reduces the number of communications, but is subject to connection persistence, re-registration, sensor power consumption, and retries. The energy for a complete duty cycle should be compared, not just a single upload current.
4G What information is required for low-power and wake-up firmware development?+
Please give priority to providing hardware power supply control, module sleep mode, wake-up source, sampling upload cycle, battery and target operating conditions. 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: the availability of sleep mode depends on the module, firmware, main controller and network conditions; battery life cannot be guaranteed by just modifying one parameter. Existing and new functions must undergo regression testing within the agreed scope after the changes.
