CC2564 - Interrupt on port stops bluetooth

Arun Kumar27

Hi,

We have created a custom board with MSP430BT5190-CC2564MODN.

We are using SPPDemo for bluetooth stack. 

We are able to discover, connect, transfer and receive data

But BT stops working if i enable any other interrupt except UART (used for bluetooth), 

And i have also observed, if we initialize other interrupts before BT Stack initialization, BT initialization fails.

Because of this i have been forced to use polling for all the features.

But i want to implement power-off feature for the MCU (by sending MCU to Low power mode), this is not possible without an interrupt ( to wake the MCU from LPMode).

What might be the problem?

Thanks

Arun

    Arun,

    1. Which MSP430 SDK version are you using?

    2. What's the smallest amount of code you can add that causes the failure?

    3. Can you isolate the problem to a single line of code using SPPDemo?

    4. Is the HAL.c:CTS_ISR() interrupt function still being called? You can verify it is by using the SetBaudRate function, which causes the CC256x to toggle the CTS line.

    5. Is the HCITRANS.c:UartInterrupt() function still being called? You can verify it is by doing any HCI communication, for example the SetLocalName command will trigger HCI Tx and Rx.

    6. Is the HAL.c:TIMER_INTERRUPT() function still being called? It should run at all times except when the processor is in low power mode.

    7. Is the HAL.c:DEBUG_UART_INTERRUPT() function sill being called? You can trigger this interrupt by typing characters into the console.

    Thanks,
    Samuel
