	HM-TRLR-S series is a low cost, high performance transparent transceiver operating at 433/915MHz. It is LoRa/FSK/GFSK/OOK modulation variety. It features small size, high output power, high sensitivity, long transmission distance and most of the parameters can be set via the command. Receive and send data to automatically switch. Use generic UART interface. It is easy to realize the wireless data transmission if provided with the UART data. It is flexible for the users to set the parameters of UART baud rate, output power, data rate, frequency select, modulation mode select etc. It is your ideal choice for designing wireless data transmission products which can be widely used on wireless data transmission field.

			===Save parameters===
			When parameters changes with the AT commands, HM-TRLR will not save the parameters to the Flash Memory automatically, HM-TRLR will read the parameters Flash Memory after reset. Therefore it is necessary for the user to save the new parameter values; you can use this command to write the parameters changed previously in Flash Memory.
			Warning: Due to the time of writing Flash memory is limited, Flash Memory may be damaged if you keep rewriting, and you can rewrite no more than10000 times.
