CC2650: Bluetooth CC2650-boostxl is not working with EVM430FR6047

Part Number: CC2650
Other Parts Discussed in Thread: EVM430-FR6047, , BLE-STACK

Hi,

I am not receiving any signal over the UART connection from the booster pack after sending a reset signal for the CC2650 board.I am using cc2650-boostxl with my application which is based on EVM430-FR6047 launchpad with latest versions of bluetooth SDK and TI-RTOS.  Please help me to resolve the issue.

Thanks,

Jaya Koduru

    Hi Jaya,

    I'm sorry, there is not enough information here for me to help you. Please explain you situation in detail and answer the following questions:

    1. What software is running on the CC2650 booster pack?

    2. What version of the BLE-Stack are you using?

    3. How is the CC2650 supposed to communicate over UART

    4. How does the EVM430-FR6047 launchpad read the UART signals

    5. Please run the software with an active debug session. Please configm that the CC2650 is able to reach the BIOS_Start statement.

    Hello Marie,

    Thank you for reaching out.

    1. The cc2650 boosterpack is running the file "simple_np_cc2650bp_uart_pm_xsbl_2_02_01_18a_merge.hex" sourced from the sdk_ble_plugin_3_20_00_24

    2. The ble stack is running the sdk_ble_plugin_3_20_00_24 but modified it to work with the MSP430 by using the code and building with the project_zero example code on CCS 9.1

    3. The cc2650 boosterpack is communicating with a UART to my board and also uses two handshake lines called "MRDY" and "SRDY" both are active low. The "SRDY" is an input signal for my board and the MRDY is an output signal indicating the master is ready to transmit.

    4. The EVM430-FR6047 is using UART A3 for communicating with the boosterpack, I have verified with a scope and also within the CCS registers to check transmit for the UART is working fine. However, the RX is where I am see trouble, there is no signal coming back from boosterpack. I am using the TI-RTOS for the drivers and the UART is in callback mode for both read/write

    5. I am not sure how to run the cc2650 in active debug. I am able to run my EVM430-FR6047 (which is the master) in active debug. However, I did verify the function of the cc2650 boosterpack by testing it out on a 3220sf board and running an out of the box example.

    A few things I noticed while trying to debug the EVM430-FR6047, the "SRDY" line which is an active low line from the slave (cc2650) is only 1.8 V however the same line is 3.3V with the 3220sf board. Not sure if it is of consequence or can have any bearing. Some pointers to debug would be great. Thank you!

    Hi Jaya, 

    Thanks for providing more details on your issue. 

    Can you confirm that you have reached BIOS_Start statement with the CC2650 device?

    Thanks,
