  • Forum Post: TI_BLE_Demo does not read acceleration, battery level or sound buzzer

    Mike Westerfield
    Questions: 1. What are the correct UUIDs for use with BLE 1.2.1? Did any change other than the battery service? 2. Where is the source code for CC2540_keyfob_SimleBLEPeripheral.hex? 3. Why doesn't the accelerometer, buzzer or battery work in the TI_BLE_Demo app for the iPhone 4s? Background...

  • Forum Post: cc2540 mini DK additional accelerometer

    Flor
    Hi, I am using CC2540 mini DK v1.1 I have some questions regarding the hardware pin connections and the accelerometer connections. 1. In the schematic of the SoC debug/flash header on the keyfob it says that pin 8 is connected to P0_3/MISO and pin10 to P0_2/MOSI. That seems inconsistent...

  • Forum Post: CC2540 2 accelerometers

    Flor
    Hi, I need some help with the CC2540 programming. I am using CC2540 mini DK v1.1 and the KeyFobDemo sample project. Until now I have been editing the cma3000d.c file to be able to read data using SPI from an external accelerometer (exact same part number as the one on board). I have successfully...

  • Forum Post: cc2540 adding new attributes UUID

    Flor
    Hi, I am using the cc2540 and the Mini DK. I am trying to add a second accelerometer with the same part number as the one that is onboard and read from it using the other USART and some pins that are not used for anything else. My first try was to read separately from the external accelerometer. And...

    Radu Iorgulescu
    On the subject of the accelerometer found in the keyfob of the CC2540 Mini DK (BLE stack 1.2) I am able to read the Characteristic Value Handle for the UUIDs: ACCEL_ENABLER_UUID 0xFFA1 (0x0033) and ACCEL_RANGE_UUID 0xFFA2 (0x0033) unfortunately, when I try to discover the handles for ACCEL_X_UUID...

    Hi, I have develop an application where I read accelerometer samples and send values at 120 Hz. In my application I am using the CC2540DK. I have several of those kits and when programing exact same application on different boards I am observing different performance. I would like to know if that is...

    What are the new UUIDs? Or, better still, where can they be found?

  • Forum Post: Set data to UART using CC2540 based board?

    Armen Dzhagaryan
    How do I send data to UART pins using CC2540? I am using OLP425 BT LE board, which is based on CC2540, and want to send some data, like accelerometer data, to UART (TxD and RxD - P0_3 and P0_5). How can I do this? Are the hal commands to establish UART connection?

  • Forum Post: TI SDK sample code string issue

    Mark Hinds
    TI persons: The SDK sample code in "accelerometer.c" contains code similar to the following: static uint8 accelEnabledUserDesc[14] = "Accel Enable\0"; I assume that this saves 2 string terminators. Is this a (strange and bad) requirement of the underlying TI code, or just an...
