Analyse du renifleur Bluetooth LE NRF52832
Nordic launched nRF52832 Sniffer for BLE broadcast packets, which is a very convenient tool for learning and debugging BLE protocols. It can parse data packets from different protocol layers in real-time, so that it can check the frame header and the data carried effectively. It provides detailed information about data packets, Received Signal Strength Indicator (RSSI), Link Quality Indicator (LQI), channel, etc. At the same time, nRF52832 Sniffer also supports the protocol parsing of the captured BLE data. nRF52832 Sniffer can be used to get the specific operation of the protocol and the types of data packets sent back and forth between devices. It is also used as a debugging tool to find out what happens when the protocol does not meet expectations. The nRF52832 Sniffer uses Wireshark as the front end and supports multiple operating systems such as Windows, Linux, and Mac OS. RF-DG-32A is a USB Donlge Sniffer based on a nRF52832 chip launched by RF-star, which supports major wireless standards, including Bluetooth Low Energy (BLE) running on Nordic nRF52832 multi-protocol system-level SoC. RF-DG-32A can provide a high data throughput communication interface through the USB device controller and can be directly connected to the computer. The nRF52832 Sniffer RF-DG-32A launched by RF-star adopts CP2102 and nRF52832 dual chips, and the nRF52832 Sniffer integrated Silicon Labs industrial-grade USB to TTL chipset CP2102 which supports independent LED indication during transmission and receiving. The USB interface uses a CP2102 chip, transfers to TTL through USB, and then connects to the nRF52832 chip through UART. Is the dual-chip design redundant? Is it better to use nRF52840 with USB support? Although nRF52840 supports full-speed USB, nRF52832 plus CP2102 chip can achieve the same USB communication function, and the overall chip price is lower than nRF52840. Le renifleur de dongle USB nRF52832 prend en charge le protocole BLE 5.0 et est rétrocompatible avec BLE 4.2.
