Point-to-point UART Lora module
Support various power consumption mode and broadcast
Super small size encapsulation
Long communication distance, low power consumption, anti-interference and high sensitivity
Smart metering/Agricultural monitoring/Automation/Smart oil field
Basic function:
Point-to-point protocol version WH-L101-P
Realize point-to-point data transmission between two serial devices by two L101-P modules
Functional diagram:
Frequency band:
WH-L101 supports high frequency band version and low frequency band version, it also supports point-to-point protocol version and concentrator protocol version.
SX127X solution:
Ultra-low power demand design
Powerful anti-interference capacity
Low power consumption:
Greatly extend battery life, be adaptive to connection rate and sleep current can be only 3μA@3.3V.
Reduce power consumption
Long communication distance:
Long transmission distance and powerful penetrating power.
Data transmission is more stable than traditional mode.
Be suited to long-distance data collection.
Anti-interference High receiving sensitivity:
Unique signal frequency spectrum amplification
Receiving sensitivity can reach -138.5dBm
Watchdog:
Software watchdog design which can realize 24 hours stable operation.
Security:
Use AT command to control data encryption transmission to provide security communication mechanism
To realize three elements of security: confidentiality, security and availability.
Work mode:
Transparent transmission mode
Realize point-to-point data transmission between two serial devices by two L101-P modules
AT command mode
Support serial AT command to query/set parameters
Fixed-point transmitting mode
In fixed-point transmitting mode, WH-L101-P can change destination address and channel flexibly when WH-L101-P is transmitting data to realize flexibly changing object module.
