TI中文支持网我将rfwsnNode中的 sendDmPacket（）移植到rfwsnconcentrator中，并用按键控制，本意是想按一次键发一次数据，可是每次按键都会发送失败，显示[Cortex_M3_0] EasyLink_transmit failed 。并且我试过用sendack发送，也是失败。请问这是什么有原因呢？
void buttonCallback(PIN_Handle handle, PIN_Id pinId)
{/* Debounce logic, only toggle if the button is still pushed (low) */// CPUdelay(8000*50);
if (PIN_getInputValue(Board_BUTTON0) == 0){//Semaphore_pend(radioAccessSemHandle, BIOS_WAIT_FOREVER);txdata++;nodeaddress=knownSensorNodes[txdata].address;PIN_setOutputValue(ledPinHandle, Board_LED1,!PIN_getOutputValue(Board_LED1));/* Send ack packet */sendDmPacket(dmSensorPacket, NODERADIO_MAX_RETRIES, NORERADIO_ACK_TIMEOUT_TIME_MS);//Semaphore_post(radioAccessSemHandle);}

你用这个芯片，应该有供应商与你们公司合作吧。供应商那边一般有技术支持的，打电话问问。
