CC2650: Where is HCI_LE_SetDataLenCmd?

Part Number: CC2650


Hi, I'm trying to use the TI Resource Explorer Development Tools for CC26xx Bluetooth Smart - v:2.01.00.44423. The version I downloaded is hci.h rev 44375 (Mon, 20 Jul 2015). 

Am I using a stale version of SensorTagStack? Where do I find HCI_LE_SetDataLenCmd? For reference github.com/ti-simplelink/ble_examples does exactly this, with the comment "This API is documented in hci.h". 

Thanks in advance!

    Hi Allan,

    The newest version of SensorTag can be found as part of BLE Stack 2.2.1 : www.ti.com/.../ble-stack if you take a look at hci.h, found in C:\ti\simplelink\ble_sdk_2_02_01_18\src\inc, you will find documentation for HCI_LE_SetDataLenCmd().

    Hi Marie, thanks for your prompt response! Your answer seems clear and correct, so I am going to verify it as answered. But the truth is that I am using an older version of Ble, the cc2650 SensorTagStack library available in resource explorer. I have only been able to use CCS Cloud, because I haven't been able to successfully import the resource explorer project into CCS desktop. 

    In any case, my question may not be relevant at this time because I don't see the new functionality supported by Android. I did find that the older functionality GATT_ExchangeMTU is supported from API 21, and I've incorporated that successfully as a workaround. 

    Again, thanks!

    Hello Allan,

    Some new handsets such as the Google Pixel and iPhone 7 support the DLE feature in a meaningful way. As new phones are announced, I would expect more devices support this v4.2 feature.

    Best wishes

    JXS, thanks for your reply!

    I'm guessing you're referring to your post here and github here.
    e2e.ti.com/support/wireless_connectivity/bluetooth_low_energy/f/538/t/542688
    github.com/ti-simplelink/ble_examples/README.md

    Unfortunately for me, I haven't been able to get ccs desktop to work correctly, and the TI resource explorer version is CC26xx 2.01.00.44423. Is there a simple way to get the ble_sdk_2_02_01_18 version of SensorTagStack into my ccs cloud workspace?

    Thanks!
