About CC 2650 STK

Other Parts Discussed in Thread: CC2540, CC2531

Hi all,

I want to Buy  CC 2650 STK of Quantity 3. Because i want to develop a BLE and 6LoWPAN applications. Before that i am interested in knowing the data transmission rates of this STK in the view of BLE and 6LoWPAN. This data Transmission rates are similar to conventional BLE as 0.7 Mbps and 6LoWPAN as 0.250 Mbps in practical cases or some what different??? I searched for this information i didn't find it. so,please provide information about this issue.

Thanks...

    6LoWPAN does not define the PHY or MAC, it is only an adaptation layer that enables you to send/receive IPv6 frames over e.g. IEEE802.15.4 MAC. You can use it with multiple data rates, for example the ones defined in the IEEE802.15.4g amendment for sub-1GHz operation. Take a look at the open source COntiki implementation of 6lowpan, which supports TI devices running on 2.4GHz as well as sub/1Ghz here: github.com/.../contiki

    BLE is ruuning on 1Mbps.

    Thanks for replay Christin.
    I will explore the Contiki for 6LoWPAN development. And also I want to monitor the network traffic of the BLE Especially with CC 2650 STK. Is it possible with the cc 2540 USB (help of TI packet sniffer software) and also is this USB hopps across all the channels(data and adv) to follow connection whenever master and slave moves??? Why because i want to see the data fields inside the different packets for more learning purpose.
    So, Please provide Information about this Issue.

    Yes, you can use CC2540 dongle with packet sniffer to trace all the activities between master and slave. However, the packet sniffer can only trace one advertising channel at a time. In order to be listening to the right channel when the connection is formed, you need to modify our simpleBLEPeripheral to only advertise at 1 channel.

    Hi Christin,

    Thanks for replay...

    what is the default Adv channel for the connection establishment in BLE??? which adv channel CC 2540 usb(with default sniffing firmware) is listening defaultly??? and Is it possible with CC 2531 USB(loaded with BLE Sniffing firmware) with the help of TI packet sniffer and also with 1 Mbps data rate of BLE or I have to go for CC 2540 USB??? Why i got this doubt is Both Usb Dongles are having same 8051 MCU and also i am having CC 2531 USB right now with me.

    The default is advertising at all 3 channels. On the CC2540 dongle side, you can choose whichever advertising channel you want to listen to.

    No, you can't use CC2531 to listen to BLE packets because CC2531 does not support BLE protocol.

    Once I got the devices of CC 2650 STK, Then I will try to develop the BLE network. At that time only I know how the communication is going on. Thanks for helping me out. It's really helpful.
