Description:The HC-42 bluetooth serial communication module is a new revison of digital transmission module based on the Bluetooth V5.0 protocol, based on the NRF52832 chip. BLE stands for Bluetooth Low Energy (Bluetooth LE, and marketed as Bluetooth Smart). BLE is a form of wireless communication designed especially for short-range communication. BLE is very similar to Wi-Fi in the sense that it allows devices to communicate with each other.When talking about Bluetooth Low Energy vs. Bluetooth, the key difference is in low power consumption. Just like Bluetooth, BLE operates in the 2.4 GHz ISM band. Unlike classic Bluetooth, however, BLE remains in sleep mode constantly except for when a connection is initiated. The working frequency band of this module is 2.4GHz ISM and the modulation method is GFSK. The module's maximum transmit power is 4dBm and the receiving sensitivity is -96dBm.The famous Nordic Semiconductor Inc. is the manufacturer of NRF52832 chip. The nRF52832 is the mid-range member of the nRF52 Series SoC family. It meets the challenges of a broad range of applications that need Bluetooth 5 feature sets, protocol concurrency and a rich and varied set of peripherals and features. In addition, it offers generous memory availability for both Flash and RAM.The nRF52832 is fully multiprotocol capable with full protocol concurrency. It has protocol support for Bluetooth 5, Bluetooth mesh, ANT and 2.4 GHz proprietary stacks.It is built around an ARM® Cortex™-M4 CPU with floating point unit running at 64 MHz. It has NFC-A Tag for use in simplified pairing and payment solutions. It has numerous digital peripherals and interfaces such as PDM and I2S for digital microphones and audio.Exceptionally low energy consumption is achieved using a sophisticated on-chip adaptive power management system.The nRF52832 takes Bluetooth Low Energy SoCs to the next level with its support for Bluetooth 5. It has an ARM Cortex M4 CPU at its heart, running at 64 MHz, it is capable of handling demanding application and communication tasks in a short timeframe. This frees up the CPU handle even more tasks, or to return to sleep mode, thus conserving precious battery energy.The nRF52832, and all SoCs in the nRF52 Series family are flash-based SoCs and are ideal for Device Firmware Updates (DFU). DFU brings total flexibility and control to the firmware running in your product. Enabling new security updates, bug-fixing and feature additions in the field.
