Engineering Scope
The low-power BLE asset tag is developed to meet the usage requirement of "warehousing needs to identify the area where pallets and tools are located". Collection, processing, communication and power supply are designed as one set of products. The project can start from new main board development, existing firmware modification or designated module integration. The development scope is confirmed based on the target function, existing foundation and delivery requirements.
Interfaces and Product Integration
Develop identity broadcast, motion status switching, anti-tampering, battery information and receiving gateway data interfaces.
Power Supply and State Scheduling
Use a longer broadcast interval when stationary, switch states when moving or being found, and then resume according to rules.
Data and System Integration
Clear connections and data formats around BLE broadcasts, motion switches or IMUs, and tamper inputs, and define recording, transmission, confirmation, and abnormal status.
Prototypes, Testing and Deliverables
The tag firmware, broadcast field, receiving gateway interface and tag binding process are formed, focusing on verifying the broadcast interval, transmit power, identification delay and deployment density; the positioning capability is determined by the overall system.
System Architecture and Operation
Use a longer broadcast interval when stationary, switch states when moving or being found, and then resume according to rules.
- Interface composition: BLE broadcast, motion switch or IMU, anti-tamper input.
- Work scheduling: Determine each status based on sampling, interaction and reception requirements, indicating which circuits continue to run.
- Exception handling: Define deadlines, bounded retries, and recovery behaviors for applicable communication, sensing, or execution tasks.
Design Conditions and Functional Limits
Area identification and precise positioning need to be determined separately according to the receiving network and algorithm.
Define power targets together with functional requirements. Battery-life estimates must specify the battery, temperature, operating cycle, event frequency and network conditions. Keep estimates separate from continuous-operation test results.

What impact does increasing transmit power have on tag recognition?+
It should be evaluated together with the installation location, occlusion, gateway density and broadcast frequency; increasing the power will change the power consumption, and the parameters are ultimately determined by field test recognition rate and delay.
Is it possible to develop only part of an existing product?+
Module development or power consumption optimization can be carried out according to the existing interface and modifiable range. For this product, you first need to check the BLE broadcast, motion switch or IMU, and anti-tamper input, and then determine the modification and regression testing scope.
How to determine the cost and period of this project?+
The evaluation is split based on deliverables such as tag firmware, broadcast fields, receiving gateway interfaces and tag binding processes; the prototype materials, structure, platform, external tests and new functions are listed separately, and quotations and nodes are formed after the requirements and interfaces are confirmed.
