    HELP !!!! While developing the uart to bluetooth communication, like below UART <---> CC2540 Keyfob <--- Bluetooth RF --> CC2540 USB dongle We met some problems 1. The default "hal_board_cfg.h" implied to use "UART DMA" mode, and will conflict if we add other...

  • Forum Post: Using UART0 on P1 (.alt2) not success

    Enid Juan
    For remaining debug ports and using uart, we are trying to use UART0 with ALT2 : P1 1. We comment out the "HAL_UART_DMA" definition in Hal_board_cfg.h to make sure we are using "HAL_UART_ISR=1" 2. We modified the _hal_uart_isr.c ==> #if (HAL_UART_ISR == 1) /* #define...

    Anna Mannila
    I would like write a logging script that would save data sent from the keyfob to my PC. For this I would need to modify HostTestRelease somewhat and to connect to the dongle via UART with an application I've written myself, not with BTool. However, at the moment I am having two problems. 1. I...

    Nicolas MICHEL
    Hello, I create a µC Firmware to Command a CC2540 with BLE-CC2540-1.1 Beta the µC send a HCI command via UART to CC2540 and CC2540 respond via UART. Since That I use BLE-CC2540-1.1, the CC2540 don't respond via UART. CC2540 have a good reception of the UART command , it made the Bluetooth...

  • Forum Post: CC2540 UART Boot loader?

    Jerome Baron
    Hi, Does anyone know where I can found a UART bootloader for the CC2540? Or any version that I could do a conversion for the CC2540? I know we can upgrade through the Debug Interface, but in my application, I already have a UART connected between the CC2540 and another microcontroller, so it...

  • Forum Post: CC2540 UART and Low Power Mode

    Nick Close
    I am currently working on a project that includes a CC2540 and an MSP430 in the design. The two devices are connected together via a UART. The MSP430 will be sending data to the CC2540 over the UART interface once a second and the CC2540 will use this data to transmit over BLE when connected to a...

  • Forum Post: RE: CC2540, loosing data on UART

    Graham Lodge
    Our findings are that either using POWER SAVING, or HCI_EXT_ENABLE_CLK_DIVIDE_ON_HALT, results in corrupted bit behaviour (the UART loses/switches its clock source half way through sending / receiving a byte - it's easy to see this behaviour if you monitor the TXD waveform). Having sorted out the...

    Hi, I am trying to transfer data to a CC2540 device through the UART link and I observe data loss during the transfer. My hardware setup is a CC2540EM plugged into a SmartRF05 rev 1.8.1 evaluation board. The evaluation board is connected to a PC through a serial cable. I slightly modified the...

    Kezhou Guan
    Hi I am currently developing a BLE device for the research industry, and I wish to allow users to flash their software onto the CC2540 Dongle. Since the dongle already has an USB port, I am wondering if it is possible to flash to device just using the USB, instead of using the debugger. Thank you...

  • Forum Post: Correct SPI pins map is in the KeyFob CC2540 reference design or CC2540 chip datasheet?

    Younes Rashidi
    Hi TI experts, I looked at KeyFob CC2540 reference design and it shows SPI MOSI, MISO, SSN and SCK are P0_2, P0_3, P0_4, P0_5 respectively but in the CC2540 chip datasheet (Table 7_1), they are P0_3, P0_2, P0_4, P0_5. It means there is something wrong because MISO and MOSI in the both resources should...
