Get Started: Installation LoRa module is a wireless transceiver which provides an easily controllable CMD interfaces(CLI/UART) that the user would send data quickly with wireless communication protocol. Prepare only one usb cable, users could use any kind of terminal utilities such as TeraTerm, Putty and HyperTerminal to access the CMD interfaces(CLI/UART). 1. Hardware introduction As the following figures, you can see a LoRa module mounted on a debugger board.
3. Get the comport information After connected micro USB cable to PC, user can check the COM number in "Device Manager", for instances, below figure indicates the COM number is 3. 4. Execute the terminal utility(PuTTY) The connection information of LoRa Module is Baud Rate 9600, Data bits 8, Parity none, Stop bits 1 and Flow control none. Here is an example using PuTTY to access UART interface. Click the Open button, then, click the Enter button on the keyboard.
Sending data This section provides command examples that used for sending user data. Example 1: Send a two-byte data 0x1234 senddata 1234 After perform this command, user will see a success state which indicates the command is correct. Due to the minimum transmission period(default is 60 seconds), user data will not be sent immediately. It can only be sent at the 60, 120, 180… second of system time. As you can see in above figure, the user data is sent at the 60 second of system time.
Commands Usage: senddata Description: Sending user data by transmission period(default period is 60 seconds) : continuously hexadecimal value without the “0x” or “0X” prefix. The length of bytes capable of being transmitted is dependent upon the data rate.
Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
Integration instructions for host product manufacturers Applicable FCC rules to module FCC Part 15.247 Summarize the specific operational use conditions The module is must be installed in mobile device.
