lora-rfm95-stm32's Issues

bug detected

There is misstake like misstype in RF95_write_burst.
You left wrong LoRa_buff instead of data in HAL_SPI_Transmit.


HAL_StatusTypeDef RF95_write_burst(char reg, uint8_t* data)
{
	int length = 0;
	uint8_t cmd = W | reg;
	HAL_StatusTypeDef err;
	
	length = strlen((const char*)data);
	
	HAL_GPIO_WritePin(LoRa_CS_GPIO_Port, LoRa_CS_Pin, GPIO_PIN_RESET);
	HAL_SPI_Transmit(&hspi_lora, (uint8_t*)&cmd, 1, 100);
	err = HAL_SPI_Transmit(&hspi_lora, (uint8_t*)data /*&LoRa_buff*/, length, 100);
	HAL_GPIO_WritePin(LoRa_CS_GPIO_Port, LoRa_CS_Pin, GPIO_PIN_SET);
	
	return err;
}

How you are verifying that Lora is further transmitting after SPI transmission is completed?

I'm using STM32F030R8T6 controller to interface with RFM96 I've used this library as a middle layer, but I'm not receiving any data on the receiver side. Any help would be great.
