DK-LM3S9D96: Example of a Bluetooth piconet implementation utilizing Stonestreet One?

Other Parts Discussed in Thread: CC2560, MSP430BT5190

We are trying to implement a piconet using the SDK included in the Stellaris development kit (i.e. DK-LM3S9D96) that comes with a PAN1325 "dougther board".  We verified with Stonestreet One this is definitely possible, but we are having a hard tome putting it together from scratch given we are on a time crunch.  I appreciate if anyone can share with us an example leading to a piconet implementation.

Thanks in Advance,

-Manuel

    Hello Manuel,

    Can you please comment on the piconet configuration/topology that you are interested in? Once we know the use cases that you are looking at we will be able to comment on how you can achieve the same.

    Best Regards,

    Stonestreet One.

    Hello,

    I'm working with Manuel on this project and can comment on the piconet configuration.

    The system involves an SPP client consisting of a TI LM3S9B96 Cortex M3 processor and a TI CC2560 transceiver. The client will utilize the Bluetopia stack. There will be multiple MSP430BT5190 based servers incorporating CC256X transceivers and running the Mindtree stack.

    In the short term, we'll be connecting two of the RF2560T accelerometer devices available in the Stellaris 2.4GHz CC2560 Bluetooth Wireless Kit to a Stellaris DK-LM3S9B96 with the PAN1323ETU installed. Data rates will be low and packet payloads will be small.

    In the long term, we'll be using similar hardware and connecting the SPP client to 3-7 MSP430 based SPP servers. Some of these will be transferring data continuously at a rate of about 50kbit/s. Others will be transferring data at 1/10thof that rate or less. Data flow will be bi-directional for all server devices, but the vast majority of the data will be moving from the servers to the client. The overall received data rate at the client will somewhat less than 300kbit/s.  

    Any example Stonestreet One can provide on setting up an SPP piconet involving a Bluetopia client connecting to multiple SPP servers would be greatly appreciated.  

    Thanks for your assistance.

    Hello Richard.

    Please let us know if you were able to connect to two servers by initiating the connection in the main thread or by increasing the memory.

    Best Regards,
