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.
