esp32ModbusTCP

WORK IN PROGRESS

This is a async Modbus client (master) for ESP32.
It uses AsyncTCP for TCP handling.
While the API is async, this lib uses the sync WiFi client as backend. All the blocking calls are moved to a seperate task.

Status

• The lib is working. Use SyncTCP branch
• Currently only functioncode 03 (read holding registers) is implemented.

To do

• implement other function codes
• try to implement AsyncTCP
