In today’s rapidly developing Internet of Things (IoT) tecnologia, wireless connectivity has become standard for communication between smart devices. No entanto, the limitations of traditional Bluetooth technology—especially the limitation on the number of connections and the fixed master/slave roles—have always been a pain point in product development. When your device needs to interact with multiple terminals simultaneously or flexibly switch between master and slave roles in different scenarios, have you ever been constrained by the limitations of Módulos Bluetooth?
Ansiot Technology introduces the ANS-BT101M, a revolutionary Bluetooth module supporting 9-way BLE multi-connection and arbitrary master/slave role switching, opening up entirely new possibilities for wireless communication between smart devices.
Why Engineers Worldwide Are Choosing the ANS-BT101M
Reimagine what’s possible with a single, ultra-flexible Bluetooth module.
The ANS-BT101M is not just another Bluetooth module — it’s a connectivity platform engineered for the next generation of IoT products. Built on the latest Bluetooth 5.1 standard, this compact powerhouse delivers capabilities that traditional modules simply cannot match.

EU. Breaking Connection Limits: 9 Devices in Parallel Communication
Traditional Bluetooth modules typically can only establish one-to-one point-to-point connections or a limited number of connections. Our Módulo Bluetooth ANS-BT101M completely breaks this limitation, enabling simultaneous connections for up to 9 dispositivos. This means:
- A single intelligent hub can manage communication with up to 8 peripheral devices simultaneously.
- Multiple data sources can transmit data in parallel to the same receiving terminal.
- Complex device networks can be built directly without relays.
Whether it’s a central controller in a smart home system simultaneously connecting multiple sensors and actuators, or a data acquisition terminal in an industrial scenario receiving information from multiple devices in parallel, this feature provides unprecedented connectivity freedom.
II. Arbitrary Switching Between Master and Slave Roles, Scene Adaptability
Traditional Bluetooth devices, once set as master or slave, have a fixed role. The ANS-BT101M Bluetooth module achieves a revolutionary breakthrough: it supports arbitrary switching between master and slave roles, allowing the same device to intelligently switch identities in different scenarios and at different times.
This feature brings unparalleled flexibility:
- Devices can intelligently switch between data collector (master mode) and data transmitter (slave mode)
- Ad-hoc network setup is easier, and devices can autonomously optimize their topology based on network conditions
- Product design does not require pre-determining a fixed role for the device within the ecosystem
Imagine a smart bracelet in a sports team, acting as a slave device transmitting data to the coach’s tablet during training, and then switching to a master device to collect information from other team members during team collaboration analysis—this dynamic adaptability completely changes the interaction model between devices.

III. Unlimited Expansion of Application Scenarios
The powerful functionality of the ANS-BT101M BLE module brings new solutions to various industries:
1. Casa inteligente
Home gateways can simultaneously connect up to eight smart devices—lights, curtains, air conditioners, security sensors, etc.—and support direct communication between devices, creating a truly seamless smart living experience.
2. Industrial Internet of Things (IIoT)
Industrial inspection robots can simultaneously receive data from multiple sensors and switch to data provider mode when needed, reporting the overall situation to the control center, significantly improving the level of industrial automation.
3. Sports and Health
Fitness equipment can simultaneously connect to multiple wearable devices, monitoring users’ various physiological indicators in real time and providing innovative interactive experiences for group training.
4. Education and Training
In multimedia classrooms, teacher terminals can simultaneously connect to multiple student devices, supporting flexible group discussions and content sharing, completely changing traditional teaching models.
