Protocol capture method
ble Smart Packet Capture Analysis Function with SmartRF Packet Sniffer Software When USB Dongle cooperates with packet sniffer for packet capture, its function is to capture packets transmitted between two connected ble devices. Using USB Dongle as a data capture device, you can capture packets from ble 4.0-capable devices such as iOS and Android. Of course, you can also capture packets from CC2540 and CC2541.
Net Bee Technology ble 4.0 CC2540 USB Dongle default firmware is 'sniffer fw cc2540 usb.hex' firmware
Step 1: Insert USB Dongle to PC and install Dongle driver
If the driver is not installed, you need to install the Dongle driver. If the PC installs the SmartRF Packet Sniffer software, the USB Dongle driver is installed by default.
Step 2: Open the Packet Sniffer software and select ble Low Energy
The third step: run the capture, analyze the data
Teach you 100% of the low-power ble 4.0 communication packets: Low-power ble 4.0 BLE broadcast channels are: 37, 38, 39, low-power ble 4.0 broadcast will be broadcast together on three channels The host may initiate a connection on one of the three channels. The packet capture device only captures the data packet that initiates the connection on a certain broadcast channel, and then it is possible to capture the next connection data packet information. Therefore, it is obvious that 100% of the method of capturing the communication packets after the low-power ble 4.0 connection is to simultaneously listen to the data packets of three broadcast channels: you need to use three CC2540 USB Dongle for low-power ble 4.0 at the same time.

How to use BTool
As a ble adapter, with the BTOOL host computer for ble 4.0 development
USB Dongle is developed with the PC host computer BTool when it is used as a ble adapter. In BTool, it can realize the functions of discovering, connecting, reading and writing data to external ble devices. These functions can be combined with USB Dongle and ble slaves to implement wireless keyboard and mouse control on a PC.
USB Dongle burns the "CC2540USBdongle HostTestReleaseAll.hex" firmware and uses it as a ble adapter. It is developed with the BTool host computer and ble 4.0.
Step 1: Insert USB Dongle to PC and install Dongle driver
Step 2: Open the BTool software and control it accordingly.
Since the USB Dongle download interface is 1.27mm pitch, in order to better use the USB Dongle and facilitate the user to re-program the program to the USB Dongle, Net Bee Technology specially designed the emulator adapter board.
