Other Parts Discussed in Thread: CC1350

Hi,

How to flash both BLE stack + TI15.4 stack so the smartphone can communicate with CC1350 and CC1350 be part of a 802.15.4 network?

Cheers,

    There's not enough flash to download both BLE Stack and TI-15.4 stack to CC1350.

    Thank you YK,

    So this chip has been made to have both BLE (2.4GHz) and 802.15.4 (over subGHz) enabled but we can't use both stack at the same time. In the example, rfWsnDmNode_CC1350_LAUNCHXL_TI, what is it used then? There are a concentrator and a node, does it use ti15.4 stack?
    Does node send beacons without BLE stack?

    The dual mode examples use a tiny link layer on top of raw RF commands which is called EasyLink. In addition, they can send BLE beacons. They do not support bi-directional communication.

    Hi,

    we just released CC1350 to the market, which is a great dual-band device and the first to come with an integrated system offering solutions and arbitration between different  bands and modulation is done through a dual-band RF driver.

    While as of today the dual band functionality is supported through the RF driver and demonstrated via RF EasyLink examples, we obviously expand to add support for more things in the future. I can't disclose much more roadmap information on the public forum (please contact a TI representative for more information) however we see that both standard stacks networking solutions like 15.4 Stack and proprietary RF are both Sub-1 GHz technologies where the integration with BLE makes lot of sense for several use cases (like beaconing or commissioning). 

    Please stay tuned! More is to come.

    Thanks,

    Hi, is it possible to replace the Esaylink with Prop RF APIs such as RF_runCmd in the rfWsnDmNode demo project?
