Read More…Lora DEMO Board is used to test wireless data transceiver module of Lora1276-C1/lora1278-C1 tranceiver module for testing system and distance,etc.Users can set the parameters of the RF module such as working mode /frequency / transmitter power / transmission data rate through the buttons, and measure the wireless communication distance
Users can set the parameters of the RF module such as working mode /frequency / transmitter power / transmission data rate through the buttons, and measure the wireless communication distance.
Working Mode There are 5 working modes in the DEMO.They are: Master mode, Slave mode,Tx Test mode, Rx test mode and Standby mode.Accordingly,they are displayed on the LCD as:Tx normal / Rx normal / Tx Test / Rx test / Standby. In Tx normal and Rx normal mode, the RF module works in the Lora mode, the digital close to DR is Coding rate and the digital close to FD is the spreading factor. In Tx test and Rx test mode, the RF module works in FSK mode, the digital close to DR is data rate and the digital close to FD is frequency deviation. In Tx normal and Rx normal mode, when one packet is transmitted, the Red LED will reverse, the number of Tx packets will increase; when one packet is received, the Blue LED will reverse, the number of Rx packets will increase:
1) Master Mode: Send 1 packet per second, and waiting for the acknowledge; 2) Slave Mode: Stay in Rx mode to wait for the data from the master, it will send back the acknowledged signal after received the data from the master. 3) Tx Test Mode: RF module continuously transmit signal; 4) Rx Test Mode: RF module is always in Rx mode; 5) Standby Mode: RF module is always in standby state.

Press [set] button, the digital close to PWR start to flash, press [up]button to change the value of output power (from 0-7)
Press [set] button, the digital close to DR start to flash, press [up]button to change the vale of coding rate (4/5,4/6,4/7,4/8)
Press [set] button, the digital close to FD start to flash, press [up] button to change Spreading Factor (6-12)
Press [set] button, the digital close to BW start to flash, press [up]button to change baud width (62.5kHz,125kHz,250kHz,500kHz)
Note: The DEMO board has FLASH memory inside, all the setting parameters will be saved automatically and keep unchanged even power-off.
