Tool/software:
Hello,
Environment:
| Hardware | LP-EM-CC2340R5 |
| Code Composer | 12.7.1.00001 |
| SDK |
Same phenomenon on SIMPLELINK-LOWPOWER-F3-SDK 7.40.00.64 8.10.00.55 |
I am using CC2340 for communication between a MCU(UART connected) and a phone.
The maximum message size is about 2058 bytes.
As title, there is possibility that CC2340 run into ICall_abort() when notifying.
I simplify the problem by modifying data stream example:
1. User connect to data stream and request MTU 517
2. Upon user writes the echo characteristic, the CC2340 starts to notify 2058 bytes each second. But even prolong period to 2 seconds, same problem happens.
3. After 200~400 notification, CC2340 run into ICall_abort(), call stack:
PDU config:
conn param: 
Of course, original example code that response inverse case character is replaced by calling start_tx_test() to start notify test.
main function is like:
#define TX_LEN_ (2058)static uint8_t tx_data[TX_LEN_];static sem_t sem_start_tx;static sem_t sem_tx_done;void start_tx_test(){ sem_post(&sem_start_tx);}static void VNG_UART_to_BLE(char *pData){ DSP_sendData(tx_data, TX_LEN_); sem_post(&sem_tx_done);}static void *UART_tx_Thread(void *arg0){ sem_wait(&sem_start_tx); uint8_t cnt = 0; while(1) { memset(tx_data, cnt, TX_LEN_); if(BLEAppUtil_invokeFunctionNoData(VNG_UART_to_BLE) != SUCCESS) { while(1){} } sem_wait(&sem_tx_done); cnt += 1; vTaskDelay(pdMS_TO_TICKS(1000)); }}void start_thread(){ if(sem_init(&sem_start_tx, 0, 0)) { while(1){} } if(sem_init(&sem_tx_done, 0, 0)) { while(1){} } pthread_t thread; pthread_attr_t attrs; struct sched_param priParam; int retc; /* Initialize the attributes structure with default values */ pthread_attr_init(&attrs); /* Set priority, detach state, and stack size attributes */ priParam.sched_priority = 1; retc = pthread_attr_setschedparam(&attrs, &priParam); retc |= pthread_attr_setdetachstate(&attrs, PTHREAD_CREATE_DETACHED); retc |= pthread_attr_setstacksize(&attrs, 1024); if (retc != 0) { /* failed to set attributes */ while (1) {} } retc = pthread_create(&thread, &attrs, UART_tx_Thread, NULL); if (retc != 0) { /* pthread_create() failed */ while (1) {} }}
Could someone enlighten me why ICall_abort() will be triggered just for notifying continuously?
Thank you very much
