Monitor Pro WH3 2BHCF-WH3 Lora Gateway
Product overview
The 4G LoRa Gateway is an ultra-long-range wireless data acquisition gateway dedicated to receiving the signals from our company’s LoRa-based temperature and humidity sensors. The 4G LoRa Gateway supports TCP, UDP, HTTP, RS485 and MODBUS-RTU interfaces and other communication interfaces.. The LoRa Gateway uses a high-performance 32-bit industrial processor and an industrial-grade wireless module, which are featured by high reliability, stability and data security. It supports local sound and light alarms, SMS alarms, GPRS alarms and other alarm methods. Unlike conventional ASK,FSK and GFSK, this gateway uses LoRa, a proprietary spread spectrum modulation technology to greatly improved the receiving sensitivity. A link budget up to 157 db has greatly increased the wireless communication distance. Combined with our LoRa sensors, the distance in open air can reach up to 5 km.

Command List
The following are ASCII commands, which can be configured via SMS or by serial port or 4G.
Note: $$$$$$ is the password and the default password is 000000.
- Attention: (1) The default configuration is to send a piece of GPRS data to the Tzone platform every 5 min;
If the SIM card needs a specified APN to use, please set the 011 command.
- Configure the RTC time of the LoRa gateway:
The machine cannot calibrate the time by itself, so when the server receives the machine data, the following information can be sent to the machine to modify the machine’s RTC time (The Tzone server already has this function):
- Format: @UTC,yyyy-MM-dd HH:mm:ss#
- Example: @UTC,2021-11-24 02:56:43#
Set the APN (Access Point Name)
- Format: *$$$$$$,011,APN,Username,Password,PDP_type,auth_type#
- Notes: The username and password can be empty.
- For example: *000000,011,cmnet,,,0,1#
- Explanation: China Mobile’s APN is “cmnet”, and the username and password are empty,PDP_type is IP,auth_type is PAP;
After you send the command via SMS, the mobile phone will receive the following message.
Receive:’011’OK *000000,011,cmnet,,,0,1#
If you send the command via serial port, the serial port will receive the following reply:
- CMD bytes: 18 *000000,011,cmnet,,,0,1#
- ComdType:011(SETAPN)
- APN number:cmnet
- Username:
- Password:
- APN Type:00
- Auth Type:01
