CC2540: cc2540

Part Number: CC2540

Hi, i have following basic doubts regarding cc2540 usb dongle(which i am currently using):

1. I wanted to interface cc2540 usb dongle with packet sniffer firmware with another TI microcontroller like TIVA board and display packet sniffing details in another display. Is it terchinically feasible.

2. If yes, pls let me know, which document to refer for data format and commands.

3. Also, can i have packet sniffing code dumping data to UART compared to USB.

Basically, as part of my studies,  i want to make a BLE sniffer with very basic features like RSSI info of ble data transfer between two other ble nodes.

Your fast response is appreciated.

Pls suggest, any other better open source tools for the same.

4. is it possible to get some info on whether some data transfer is happening in each channel, other than advertisement.

    Hi Sanood,

    We don't release the packet sniffer firmware source code so you will need to use the hexfile provided as is. Here is the link to the packet sniffer guide: processors.wiki.ti.com/.../BLE_sniffer_guide

    In order to figure out how to decode the packets, you would probably have to use a UART sniffer and observe the commands that are being sent between the SmartRF Packet Sniffer PC application and the dongle. Then you could model your TIVA code from that.

    Hi Rachel, thanks for quick response.

    Can u direct me to the guys who developed packet sniffer PC application or can u get me one doc on the same from the design team.
    My intention is to make a small interface to the pkt sniffer via uart and make a hand held mobile sniffer using TiVo board which we have used extensively as part of lab work.
    Thanks in advance.
