LORA MESH Network RF module-100mW 1W 5W-LoRa-MESH series Mesh network modules
Lora-MESH series are ultra long-distance MESH network data transceiver modules, which adopts the high-performance SX1276/1278 from Semtech. They have NODE and ROUTER working modes, can be as smart repeaters automatically. It is easy to build a network without a blind area or distance limitation. When used as a repeater, just put the module in the area where the signal is weak to extend the range. To avoid interference, Lora-MESH provides 40 frequency channels. Lora-MESH is flexible but easy to use. It comes with many parameters, such as frequency, data rate, output power, Node ID. Users can configure the parameters through a PC or customer’s own device.

Functional Description:
Operation
1) Power on Reset
After powered on reset, the TX LED (Red) and RX LED (Blue) will blink 3 times, 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 modules enter into working mode, the serial and RF are both in receiving mode then.
In NODE working mode, LORA-MESH module stays in receiving mode and wait for the series signal and RF signal.
LORA-MESH module can connect with any device which is the standard 232/485/TTL interface.
-
When the series signal comes, LORA-MESH 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 the RF signal comes, LORA-MESH 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.
(a) Parameter matching
The series parameter between the device and MESH module should be the same, frequencies, channels and RF parameters should be the same in Tx and Rx.
Note: the Default setting is: Baud rate=9600bps,data bit=8,stop bit: 1,parity bit: none。
(b) Delay Time
Data delay exists between series input of the transmitter and series output of the receiver. This Delay Time is different from the series data rate, RF data rate, and payload length.
(c) Package transmission
One packet cannot exceed 56 bytes. LORA-mesh can’t work when the payload length exceeds 56bytes.
3)Router mode
When set as ROUTER, in working mode, LORA-MESH module can repeat the RF signal in the same network automatically to extend the distance.
Normally, 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.
4)Setting Mode
In working mode, pull low the SET pin to force LORA-MESH module into setting mode. When using the USB bridge board, simply put on the short cap to enter into setting mode.

FAQ:
A. Why module cannot communicate properly?
1) Check if there is a power connection error;
2) Check if the module is enabled (CS / SET both high);
3) Check if the band, channel, rate, NET ID has set to the same;
4) Check if the module is damaged(light is on?)
B. Why transmission distance is not as far as it should be?
1) Power supply ripple is too large;
2) The antenna types do not match, or not properly installed;
3) The surrounding environment is harsh, strong interference sources;
4) Surrounding co-channel interference;
C. Why receiving data incorrect?
1) Check if the interface compatible with the device;
2) Improper parameter settings.
3) The module data interface is bad.
