Question
no radio Rx timeout after Radio.Rx() called
Hi,
I use STM32WLE5CBU6. I created SubGHz Phy project. Device entered stop 2 mode, exit stop 2 mode when the alarm B interrupt issue then the Radio.Rx(3000) is called to receive data.
my RTC Alarm interrupt function below,
void HAL_RTCEx_AlarmBEventCallback(RTC_HandleTypeDef *hrtc)
{
UTIL_LPM_SetStopMode((1 << CFG_LPM_LoRa_Id), UTIL_LPM_DISABLE);
DebugPuts("\rAlarm B.");
/* Radio Receive */
DebugPuts("\rRadio Receive.");
Radio.Rx(3000);
}my SubGhz App Init() function below,
void SubghzApp_Init(void)
{
/* USER CODE BEGIN SubghzApp_Init_1 */
DebugPuts("\rSMETER.");
/* Get SubGhz-Phy APP version */
DebugPrint("\rAPPLICATION_VERSION: V%X.%X.%X", (uint8_t)(APP_VERSION_MAIN), (uint8_t)(APP_VERSION_SUB1), (uint8_t)(APP_VERSION_SUB2));
/* Get MW SubGhz-Phy info */
DebugPrint("\rMW_RADIO_VERSION: V%X.%X.%X", (uint8_t)(SUBGHZ_PHY_VERSION_MAIN), (uint8_t)(SUBGHZ_PHY_VERSION_SUB1), (uint8_t)(SUBGHZ_PHY_VERSION_SUB2));
/* USER CODE END SubghzApp_Init_1 */
/* Radio initialization */
RadioEvents.TxDone = OnTxDone;
RadioEvents.RxDone = OnRxDone;
RadioEvents.TxTimeout = OnTxTimeout;
RadioEvents.RxTimeout = OnRxTimeout;
RadioEvents.RxError = OnRxError;
Radio.Init(&RadioEvents);
/* USER CODE BEGIN SubghzApp_Init_2 */
/*calculate random delay for synchronization*/
random_delay = (Radio.Random()) >> 22; /*10bits random e.g. from 0 to 1023 ms*/
/* Radio Set frequency */
Radio.SetChannel(RF_FREQUENCY);
/* Radio configuration */
DebugPuts("\r---------------");
DebugPuts("\rLORA_MODULATION");
DebugPrint("\rLORA_BW=%d kHz", (1 << LORA_BANDWIDTH) * 125);
DebugPrint("\rLORA_SF=%d", LORA_SPREADING_FACTOR);
Radio.SetTxConfig(MODEM_LORA, TX_OUTPUT_POWER, 0, LORA_BANDWIDTH,
LORA_SPREADING_FACTOR, LORA_CODINGRATE,
LORA_PREAMBLE_LENGTH, LORA_FIX_LENGTH_PAYLOAD_ON,
true, 0, 0, LORA_IQ_INVERSION_ON, TX_TIMEOUT_VALUE);
Radio.SetRxConfig(MODEM_LORA, LORA_BANDWIDTH, LORA_SPREADING_FACTOR,
LORA_CODINGRATE, 0, LORA_PREAMBLE_LENGTH,
LORA_SYMBOL_TIMEOUT, LORA_FIX_LENGTH_PAYLOAD_ON,
0, true, 0, 0, LORA_IQ_INVERSION_ON, true);
Radio.SetMaxPayloadLength(MODEM_LORA, MAX_APP_BUFFER_SIZE);
/* USER CODE END SubghzApp_Init_2 */
}the radio status is RF_RX_RUNNING everytime.
Please support me.
Thanks.
