For example, BLE blood pressure monitor and heart rate monitor, greatly increase efficiency of patient monitoring and care experience. Logistics Tracking: High-power Bluetooth devices also play important roles in logistics tracking and asset management. Efficient remote tracking and management of goods and assets in warehouses and transport vehicles can improve logistics efficiency and accuracy. Smart Agriculture: Environmental monitoring and automation in large fields or greenhouses, achieve precision farming. While these applications prioritize transmission power and range, higher transmit power also leads to increased power consumption. Therefore, when selecting Bluetooth Low Energy modules for different applications, it's essential to consider factors such as transmission power, communication range, antenna, and power consumption. High-Power BLE Modules Most of BLE modules have a maximum TX power of 4 dBm or 8 dBm, but a few exceed this. As an example, RF-star’s CC2652P, CC2652P7 series modules can output +20 dBm, while EFR32BG24/MG24 modules can output +19.5 dBm. TI CC2652P-Based Modules RF-BM-2652P2 and RF-BM-2652P2I wireless modules are based on the Texas Instruments (TI) CC2652P SoCs with a built-in PA and maximum transmit power of +2...

    A View of BLE Connection Roles: Central / Master vs. Peripheral / Slave
    In the world of Bluetooth Low Energy (BLE), BLE devices are designed to play specific roles that dictate how they interact within the BLE ecosystem. To fully leverage the benefits of BLE technology, it is essential to understand the roles of BLE devices in the communication process. In this article, we introduce the common roles in BLE connection, the differences between Central and Peripheral roles, and how to choose well-suited BLE modules for your projects. The two primary BLE roles are the Central and Peripheral roles. Central / Master vs. Peripheral / Slave The Central is a device with powerful and rich resources. The BLE central device initiates an outgoing connection request to an advertising peripheral device, and processes data provided by the peripheral. In a way, it can be regarded as the active role, also referred to as a “master”.  A typical example of a central device is a smartphone, which can connect to several peripherals simultaneously, collecting, and processing data from each. On the other hand, the Peripheral is a typically low-power, resource-constrained device that provides data. It accepts an incoming connection request after advertising its presence to other devices in the vicinity. Generally, the Peripheral is meant to stay put until someone decides to connect with it. Hence, it is also called a “slave”. A peripheral is usually a small device like a smartwatch, a temperature sensor, a heart rate monitor, etc. The BLE specification does not limit the number of slaves a master may connect to, but there is always a practical limitation, especially on different models of modules. For instance, RF-star’s BLE modules based on TI CC2642R, CC2340, Silicon Labs EFR32BG22 and Nordic nRF52840 nRF52832 SoCs play a master and multi-slave roles. Support at most 8 simultaneous and stable connection devices, that is 7 slaves and 1 master. Furthermore, the EFR32BG22 and CC2340-based Bluetooth Low Energy modules can connect simultaneously to multiple masters and slave devices. After knowing the definition of connection roles in BLE communication, let’s move to their distinction. Differences Between Central and Peripheral While BLE Peripherals and Centrals both contribute to BLE communication, they have unique features, capabilities, and requirements. Here is a table for you to clearly distinguish each other. As the above shows, a Peripheral in BLE is a low-power device, mainly providing data. It wakes up only to advertise or transmit data while spending most of the time in a low-power sleep mode. A Central, in contrast, is power-hungry, continuously scanning for peripherals and managing multiple connections. Some Central devices, like smartphones, can maintain several connections simultaneously, making them suitable for data aggregation and processing, whereas peripherals are commonly found in battery-powered devices like sensors, wearables, and beacons. Knowing these differences, is it clear how to choose between a master and slave ...
