Learn Modbus with full protocol stacks, or get all data from your remote Modbus RTU devices by defining your full modbus map, or use your mobile devcie to simulate Modbus devices or sensors.

This Modbus App has three Apps in one:
(1) Modbus Client (Master)
(2) Modbus Server (Slave)
(3) Modbus TCP Sensors Server

Four Interfaces:
(1) Bluetooth SPP & BLE
(2) Ethernet
(3) Wi-Fi
(4) RS232/485 USB Serial ports via USB OTG

Eight Protocols to choose from:
(1) Modbus TCP
(2) Enron/Daniels TCP
(3) Modbus RTU over TCP
(4) Modbus UDP
(5) Modbus RTU over UDP
(6) Modbus TCP Slave/Server
(7) Modbus RTU
(8) Modbus Serial ASCII

Push data to cloud:
> MQTT
> Google Sheets
> ThinkSpeak

Sensor Server:
Explore Sensor Server: Remotely monitor mobile device's sensors using Modbus Protocols

Import/Export:
Import in CSV format. Export data to CSV format every second, minute, or hour. Export configuration data via email or log to ThinkSpeak or Google Sheets Cloud platforms
