LoRa611Pro-100mW MESH LoRa Wireless Transceiver Data Transmission Module
The Lora Pro module is a new series of upgraded networking wireless communication modules from Wireless. It is based on Semtech's SX127X chip and uses advanced LoRaTM spread spectrum modulation frequency hopping technology to achieve high sensitivity. The penetrating power and communication distance are far superior to the current FSK and GFSK products and have stronger anti-interference. In order to meet the application needs of different customers, we design the module software of this series as an all-in-one way. Users can switch between different working modes through the PC software configuration module. In MESH mode, the routing module has automatic routing. Function, the user can form a network transmission without a blind zone without distance limitation by means of multi-module combination. At the same time, users can also encrypt AES128 wireless data through PC software or serial port instructions, making data transmission more secure. The Lora611Pro module is designed for 100mw output power and is available in TTL/RS232/RS485 levels. It is widely used in wireless remote transmission control. Note: The Lora Pro series can be configured to be compatible with our previous Lora data transmission modules.
Feature and application:
Transmission distance in open area up to 8000 meters @ 91bps
AES128 Data encryption
MESH & Node working mode
Sensitivity: -139 dBm
Max output power: 500mW/1W（+30/+27dBm）
Working voltage: 3.3 ~ 6.5 V
Working temperature: -40 ~ +85 °C
Remote control telemetry
Remote meter reading
Industrial data acquisition
Wireless data communication
Typical application circuit:
1) Power-on Reset
Standard supply voltage of 5V (ordinary lithium battery of 4.2V is also applicable)，After powered on reset, the TX LED (Red) and RX LED (Blue) will blink 3 times,(If no lights, the module may be damaged), The total reset time is around 2s.
2) Working Mode
The CS and SET Pin is internally pulled up. Pull CS pin high or leave it open will make the module enter into working mode.
In working mode, LoRa611 stay in receiving mode and wait for the series signal and RF signal.
The module can connect with any device which is a standard TTL/RS232/RS485 interface.
When the series signal comes, the module will check the input series signal if there is any error, and then transmit the received data out via RF automatically if no errors found.
When RF signal comes, the module will check the input RF signals if there is any error, and then transmit the received data out via series port automatically if no errors found.
When one packet is transmitted successfully, the Red LED will blink once.
When one packet is received and verified with no problem, the Blue LED will blink once.
The upgraded LoraPro series can be compatible with all versions of our LORA data before. The user can use PC software to configure the module to work mode according to his application needs. Now the comparison between several versions is as follows:
Pin and dimension:
Normal mode PC settings——( Work Mode = Normal + disable Encryption )
AES mode PC settings——( Work Mode = Normal + Enable Encryption )
MESH mode PC settings——( Work Mode = MESH ;Mode = Router or Node)
When set as ROUTER, in working mode, the module can repeat the RF signal in the same network automatically to extend the distance.
Normally, the Router module is connected with the external power supply to keep a long time in receiving mode and repeat the signal to extend the range.
3) Setting mode
In working mode, pull low the SET pin to force the module into setting mode. When using USB
bridge board, simply put on the short cap to enter into setting mode.
Why module cannot communicate properly?
a) Check if the band, channel, rate, NET ID has set to the same;
b) Check if there is a power connection error;
c) Check if the module is enabled (CS high);
d) Check if the antenna connection is not correct;
e) Check if the module is damaged.
Why transmission distance is not as far as it should be?
a) Power supply ripple is too large;
b) The antenna types do not match, or not properly installed;
c) The surrounding environment is harsh, strong interference sources;
d) Surrounding co-channel interference;
Why receiving data incorrect?
a) Improper parameter settings;
b) The module data interface is bad.
