CC2340R5: DSP_sendData stucked at ICall_abort()

YW Lin

Part Number: CC2340R5

Hi TI members,

Below is my building environment:

Software	Version
Code Composer Studio	12.3.0.00005
SimpleLink SDK	7.10.00.35
XDCtools	3.62.1.16_core

We are using data_stream project with UART enabled.

When we received messages from UART RX, we would like to send it to some other apps.

We tried to do this with something like this:

status = DSP_sendData(&uartReadBuffer, 128);

while uartReadBuffer was an uint8 array that we used UART2_read to store the messages from RX.

But when we ran in debug mode and tried to go through this line, it stucked at "ICall_abort() at icall_POSIX.c:0 0x00026AFC" and wouldn't either receive any messages or send anything.

Did we misuse the APIs or how would you recommend us to modify our codes?

Thanks.

Hi,

Can you share where you are calling the the sendData function? Is function being called from within an interrupt context? If so, then this will likely cause issues. This function must be called from a task context.

Hi Jan and Isaac

We found we can't call DSP_sendData directly in a freertos task, we need to call it indirectly by BLEAppUtil_invokeFunctionNoData() in a freertos task, any idea about this issue ?

BLEAppUtil_invokeFunctionNoData(SendUARTOverBLE);

void SendUARTOverBLE(){
    bStatus_t status = SUCCESS;

    status = DSP_sendData((uint8 *)uartReadBuffer, bytesRead);
    if ( status == SUCCESS )
    {
        Log_printf(LogModule_App1, Log_DEBUG, "DSP_sendData SUCCESS");
    }
    else
    {
        Log_printf(LogModule_App1, Log_DEBUG, "DSP_sendData FAIL");
    }
}

Hi,

The BLEAppUtil_invokeFunctionNoData() allows you to easily call functions within the BLEAppUtil framework. I believe this is expected. Are you able to implement the desired behavior when calling the function in this way?

Best Regards,

Hi Jan,

Yes, if we call DSP_sendData by BLEAppUtil_invokeFunctionNoData, cc2340 can send packets to air.

Hi,

Understood. If the function works well, then it should be okay to continue using the invoke function to trigger the packet transmission.

Best Regards,

Jan
