# Modbus assumptions, dependencies and constraints
|
|
|
|
1. Current implementation of Modbus has limitation: maximum frame size should be less than 120 bytes (default UART receive FIFO full threshold value).
|
|
This limitation is removed in ESP-IDF v4.2.
|
|
|
|
2. The only one instance of Modbus port can be initialized at the same time.
